Cryptography: Crash Course Computer Science #33
 
12:33
Today we’re going to talk about how to keep information secret, and this isn’t a new goal. From as early as Julius Caesar’s Caesar cipher to Mary, Queen of Scots, encrypted messages to kill Queen Elizabeth in 1587, theres has long been a need to encrypt and decrypt private correspondence. This proved especially critical during World War II as Allan Turing and his team at Bletchley Park attempted to decrypt messages from Nazi Enigma machines, and this need has only grown as more and more information sensitive tasks are completed on our computers. So today, we’re going to walk you through some common encryption techniques such as the Advanced Encryption Standard (AES), Diffie-Hellman Key Exchange, and RSA which are employed to keep your information safe, private, and secure. Note: In October of 2017, researchers released a viable hack against WPA2, known as KRACK Attack, which uses AES to ensure secure communication between computers and network routers. The problem isn't with AES, which is provably secure, but with the communication protocol between router and computer. In order to set up secure communication, the computer and router have to agree through what's called a "handshake". If this handshake is interrupted in just the right way, an attacker can cause the handshake to fault to an insecure state and reveal critical information which makes the connection insecure. As is often the case with these situations, the problem is with an implementation, not the secure algorithm itself.

Gambling with Secrets: Part 5/8 (Encryption Machines)
 
09:48
Explore how the one-time-pad was applied during WW2 with the use of rotor encryption machines. The German's Enigma machine would have been nearly impossible to break if it didn't rely on human operators making "random" choices. This video purposely ignores many details of the Enigma (such as the plug-board) and how it was broken. The goal is to explain the strength of the machine in terms of the key space. Also, pseudorandom sequences (no matter how you generate them) require a random initial seed. This will be fleshed out in the final chapter on Public Key Cryptography.

Криптография (Cryptography) Шифрование данных и дешифровка Encryption and Decryption RSA
 
02:03
Криптография - это наука об обеспечении безопасности данных. Она занимается поисками решений четырех важных проблем безопасности - конфиденциальности, аутентификации, целостности и контроля участников взаимодействия. Шифрование - это преобразование данных в нечитабельную форму, используя ключи шифрования-расшифровки. Шифрование позволяет обеспечить конфиденциальность, сохраняя информацию в тайне от того, кому она не предназначена. ➤ Для удобства участникам передачи зашифрованного сообщения дают следующие имена: Алиса — отправитель, Боб — получатель, Ева — пассивный перехватчик, Меллори (Man-in-the-middle) — активный перехватчик, может не только перехватывать передачу, но и подменять содержимое. ➤ Криптография не занимается: защитой от обмана, подкупа или шантажа законных абонентов, кражи #ключей и других угроз информации, возникающих в защищенных системах передачи #данных. ➤ Криптография — одна из старейших наук, её #история насчитывает несколько тысяч лет. Ещё в древнем Риме Гай Юлий Цезарь, который совершенно не доверял гонцам, опасаясь что те прочтут его письма, прибегал к #шифрам. Для того, чтобы избежать вероятности того, что гонец всё же осмелится и захочет прочесть послание Цезаря, он, отправляя письма генералам, менял каждую букву на D, каждую B на E, и так далее. И лишь те, кто знал правило «сдвига на 3» мог расшифровать его послание. Проблема защиты информации и сегодня является наверное одной из самых актуальных. Шифрованием, кодированием и многими другими методами, созданными для обеспечения конфиденциальности информации занимается одна из древнейших наук – криптография. Какие шифры бывают и есть ли системы шифрования,которые невозможно взломать и раскрыть? Какие методы и системы защиты информации использует криптография? Как можно защитить себя от атаки хакеров? Об этом расскажут: кандидат психологических наук - Сергей Николаевич Ениколопов, кандидат физико-математических наук - Иван Владимирович Чижов и доктор физико-математических наук - Владимир Сергеевич Анашин ➤ Изначально криптография изучала методы шифрования информации — обратимого преобразования открытого (исходного) текста на основе секретного #алгоритма или ключа в шифрованный #текст (шифротекст). Традиционная #криптография образует раздел симметричных криптосистем, в которых зашифрование и расшифрование проводится с использованием одного и того же секретного ключа. Помимо этого раздела современная криптография включает в себя асимметричные криптосистемы, системы электронной цифровой подписи (ЭЦП), хеш-функции, управление ключами #key, получение скрытой информации, #квантовую криптографию. ► ► ► ► ► ► ► ► ► ► ► ► ► ► ► ► ► ► ►► ► ► ► ► ► ► ► ► ► ► ICOTRACKER.NET специализируется на оценке компании с запланированным ICO "ИКО".

Most DIFFICULT Codes That Were Ever CRACKED!

Check out the Most DIFFICULT Codes That Were Ever CRACKED! From breaking famous uncracked codes to some of the most mysterious ciphers finally solved using computer science, this top 10 list of incredible codes & ciphers that were finally figured out will amaze you! Follow us on instagram! https://www.instagram.com/katrinaexplained/ Subscribe For New Videos! http://goo.gl/UIzLeB Watch our "REAL Mermaid Sightings Around The World!" video here: https://youtu.be/ChM0CBRmVsM Watch our "Most Amazing Cities Found UNDERWATER!" video here: https://www.youtube.com/watch?v=rUqxhYJqGhU Watch our "Most EXPENSIVE Private Jets Owned By BILLIONAIRES!" video here: https://www.youtube.com/watch?v=nyqlXe3-jrA 10. The Zimmerman Telegram During times of war, messages are often sent in code to prevent the enemy from finding out about secret plans. Spies are everywhere, and if the message is ever decoded by an unintended recipient, it can change the course of history… and that’s exactly what happened in 1917. 9. The Battle of Midway The Battle of Midway, which took place between the 4th and 7th of June, 1942, was one of the American military’s biggest victories over the Japanese navy during the second world war. In this battle over 3,000 Japanese sailors lost their lives and 4 aircraft carriers were destroyed, while the Americans lost 300 sailors and one carrier. It could have all been different, though, had US cryptographers not intercepted and decoded Japanese transmissions. 8. The Babington Plot The Babington plot was an attempt, in 1586, to assassinate Queen Elizabeth the First, protestant daughter of King Henry VIII. The goal was to replace her on the throne with Mary Queen of Scots, who was her Roman Catholic cousin. On July 6th that year, Anthony Babington, encouraged by support from abroad (mostly Spain) wrote a long letter to Mary, who at the time was already in prison. 7. Olivier Levasseur According to legend, the notorious French Pirate, Olivier Levasseur, managed to acquire a huge fortune during his piracy across the Caribbean and West Africa- most notably in 1721 when he and his crew captured a Portuguese treasure ship that had become grounded on a sandbar during a storm- an act that is said to be one of the greatest paydays in the history of piracy. 6. Poe’s Challenge Edgar Allan Poe was a renowned writer and poet, known for his stories of mystery… but he was also fascinated with ciphers and codes. He even wrote a story, The Gold Bug, about the solution to one. In 1840, he wrote an article for Graham's magazine called ‘A Few Words on Secret Writing' in which he invited readers to send him coded messages for him to decipher. 5. Linear B In 1900, among the ruins of a Bronze age palace in Knossos, Greece, archaeologists found a script that resembled nothing that had ever been seen before. Containing images of swords, chariots, and countless other small pictograms, this system of writing became known as Linear B and would prove to be a mystery for the following 50 years. 4. Frank Sidebottom Frank Sidebottom was the papier-mâché headed comedy persona of English musician Chris Sievey. Throughout his career in the 80s and 90s, he fronted tv and radio shows and even reported for the local news. He created numerous newsletters and writings over this time, too, and these were often accompanied by symbols around them… ones that people long suspected had a meaning, but they couldn't work out what it was. 3. Chaocipher The Chaocipher was created by John Francis Byrne in 1918 and was what he described as being unbreakable… yet simple. So simple, in fact, that it only required two rotating discs that were small enough to fit into a cigar box and could be operated by a ten-year-old. He offered a cash reward to anyone who could crack it, but this is something that would never be claimed. 2. The Copiale Cipher Created in the 1730s, the Copiale cipher is a 105-page manuscript that has baffled researchers ever since…That is until 2011 when it was finally decoded. Consisting of 75,000 handwritten characters; including arrows, shapes, runes, math symbols, roman letters, and Greek letters… there were only two examples of plain text in the entire book. 1. The Enigma Code The Enigma was an enciphering machine used by the German armed forces during the second world war to send secure messages. Early on, Polish mathematicians had figured out how to read these messages, but once the Germans realized this, they began to change the cipher system daily, making it virtually impossible to decipher.

Braille Box for Escape Rooms- Can you find the clue?
 
05:50
This is a puzzle built primarily for Escape Rooms. It will be customized to a 4 digit or 4 letter sequence that you provide The goal for your guests is to find the secret code. When discovered , the code can be used in whatever manner the Escape Room desires, such as perhaps the combination to a lock or door. Or perhaps a 4 letter word that is needed in the next puzzle challenge. The box 6” x 6” x 3” box is solid and will not open. It is also empty. On the bottom size is a hole large enough to easily fit a finger. Around the outer sides of the box are the digits 0 to 9 with their braille equivalent. Your quests will no doubt wonder what an empty box is for! There is a secret inside the box though… The bottom of the box has the numbers 1 to 4 laser engraved at 90 degree intervals around the center hole. If one sticks a finger in the box and feels under each of these locations, a series of raised dots can be felt. Eureka! However, now those raised dots must be interpreted to numbers using just your finger senses combined with braille table glued to the sides of the box. This is a fun and unusual way for your guests to find a code. The design was the result of an Escape Room owner asking us if we could build something so that a blind person could actively participate in the Escape Room Experience. Though a sighted person can solve this; the edge would certainly go the person who can read braille with their fingertips!

Differential Cryptanalysis for Dummies - Layerone 2013
 
38:49
This talk is an introduction to finding and exploiting vulnerabilities in block ciphers using FEAL-4 as a case study. Attendees will learn how cryptanalysis can be used to break ciphers by finding the key with less computational effort than exhaustive search. After an introduction to block cipher components and structure, we will study the incredibly broken FEAL-4 algorithm. By exploiting statistical biases in the cipher, attendees will learn how to build a differential attack and ultimately recover the key. Attendees should have a basic understanding of binary operations like XOR and a general familiarity with bits and bytes. Jon will guide attendees through the fundamentals of modern cryptanalysis while keeping the math to a minimum. That said, this talk is focused on the nitty gritty details of cipher vulnerabilities and how differential cryptanalysis can be applied to them. Jon is also able to provide overviews of other cryptanalytic attacks (linear, boomerang, impossible differential, slide, etc..) if time permits and there is interest. About the speaker: Jon King is an active-duty member of the US Navy that enjoys breaking security as a hobby. He primarily focuses on finding vulnerabilities in high-security locks and tamper-evident devices. Additionally, Jon studies cryptanalysis with a focus on implementing realistic attacks against modern block ciphers. Despite having very little math background, he has digested the writings of the academic cryptography world and is available to translate their esoteric math-talk.

Bitcoin 101 - Modelling the Price of Bitcoin - Is a $100,000 bitcoin possible?
 
26:45
Can the price of Bitcoin reach two thousand dollars, ten thousand, or more? Even if you consider the blockchain as the fundamental innovation of Bitcoin, price matters, and indeed, the higher the price, the more Bitcoin is protected. In this video we focus on price, specifically in the attempt to model the price of Bitcoin. Big investors make price models for assets. Trouble is they keep this information private. Models may not predict the price, but the certainly provide a better understanding. In this video, James walks you through the concepts and challenges of modelling the price of Bitcoin. From velocity, transaction volume, supply, to all the big markets Bitcoin proposes to disrupt (hedge funds, gold, e-commerce, money supply, remittances etc). Better still we walk you through the alpha version of our open-source model. The live model: http://worldbitcoinnetwork.com/BitcoinPriceModel-Alpha.html GitHub code: https://github.com/wobine/blackboard101/blob/master/BitcoinPriceModel-Alpha.html Great post by Robert Sams: http://cryptonomics.org/2014/02/18/can-we-value-bitcoin/ By playing around with the model, you'll find yourself understanding the concept in a richer way, and soon you'll be walking and talking bitcoin price like a pro.

Adam Young, Malicious Cryptography - Exposing Cryptovirology (February 27, 2004)
 
55:51
From the CISR video library (http://www.cisr.us) Dr. Adam Young, Cigital Malicious Cryptography - Exposing Cryptovirology February 27, 2004 at the Naval Postgraduate School (http://www.nps.edu) ABSTRACT Cryptography is commonly regarded as an enabling technology. It allows for confidential information transmission over untrusted networks as well as the ability to prove the origin of messages. It is a technology that is critical in an on-line world. However, cryptography is also a very powerful disabling technology. In recent years there has been a significant amount of research into using well-known cryptographic paradigms and tools for the purposes of undermining the security of computer systems once internal access is acquired. This talk will give an overview of a new book that details this dark side of cryptography. The book is entitled "Malicious Cryptography: Exposing Cryptovirology," and is authored by Adam Young and Moti Yung (published by John Wiley & Sons). Some of the more noteworthy attacks that are described in the book are the following. It is shown how to use public key cryptography to mount reversible denial-of-service attacks. A virus attack is detailed in which the virus asymmetrically encrypts host data (that has not been backed-up). The effects of the attack can only be reversed if the attacker agrees to use his or her own private decryption key. It is shown how to devise a cryptovirus that steals data from a host machine without revealing that which is sought, even if the virus is under constant surveillance. It is shown how to design a password snatching cryptotrojan that makes it virtually impossible to identify the author when the encrypted passwords are retrieved. Furthermore, it is intractable to determine if the cryptotrojan is encrypting anything at all when all even when all of its actions are recorded and analyzed. Finally, cryptotrojans are described that attack industry-standard cryptosystems. By design, these Trojans give the attacker covert access to the private keys of users and are extremely robust against reverse-engineering. When implemented in tamper-resistant devices the theft cannot be detected by anyone save the attacker. The book also covers various countermeasures that can help protect against these attacks. About Dr. Adam Young Dr. Adam Young is a Research Scientist at Cigital. He is responsible for researching and developing software and techniques to help support the research goals for Cigital's research contracts. In his first year at Cigital, Adam has served as a primary investigator on a research project for the DoD. Adam Young recently worked for Lockheed Martin Global Telecommunications. Prior to this he was a Member of Technical Staff (MTS) at Lucent Technologies in the Secure Systems Research Division. Before joining Lucent he worked as a cryptography consultant for CertoCo (a spin-off of Banker's Trust). Dr. Young holds a BS in Electrical Engineering from Yale University, an MS in Computer Science from Columbia University, and a PhD in Computer Science from Columbia University that was awarded with Distinction. He gives invited talks regularly and will be giving an upcoming talk at the Palo Alto Research Center (PARC) on his forthcoming book [[i]]. He will also be giving an invited talk at the Sixth International Joint Meeting of the AMS and the Sociedad Matematica Mexicana (SMM), Special Session on Coding Theory and Cryptography, in Houston. The session is being held by Neal Koblitz. Dr. Young has also given invited talks at NYU, Bell Labs, and Sandia National Labs. He has taught computer science courses at Columbia University and is a member of the International Association for Cryptologic Research (IACR). He has published numerous papers on cryptography, computer security, and algorithmic number theory and his next paper will be presented in the Cryptographer's Track of the RSA Conference, 2004 [[ii]].

Enigma Morph Encoder
 
09:18
Google (and probably other email providers too) read every single email that is sent to a Gmail account in order to place "relevant" advertising around your email. In recent times there has been a hoo-hah about the NSA reading emails too. Or maybe you just would like to keep personal emails that you receive at work confidential from your employer. The Enigma Morph Encoder is for use to encrypt you messages such as your emails to prevent others who do not know the Key Phrase and/or do not have access to the Enigma Morph Encoder from reading them. An encoded message once decoded will retain all punctuation and spaces. Curly quotes (" ") and (' ') are converted to plain quotes (" ") and (' '). Tab characters ( ) and multiple spaces ( ) are converted to a single space ( ). Any unrecognized punctuation (including letters with accents) are converted to the Registered Trademark symbol (®). Formatting is not retained so new lines are usually converted to double Registered Trademark symbol (®®). All Alphabetic characters are encoded as UPPERCASE letters. The following two messages are examples to demonstrate how the Enigma Morph Encoder works. In each case the message has been encoded with just the default Key Phrase (Type your Key Phrase here.) with the default Encryption Depth of 1. Example#1 Message#1 Dear Jane, I hope you are well. Encoding#1 SPET38PK2P VJ1656E9PK YJPAYGYFJZ LFB40R3MVI You will notice that where identical letters in the message are encoded they are rarely encoded as the same character each time, and where they are it is purely coincidental. I.e. in the above example the 2nd and 9th characters of Message#1 is an "e", but the 2nd and 9th characters in the encoding are "P" and "2". You will also note that the 17th character of the message is also an "e" and that the 17th character of the Encoding is "E" (spaces in the encoding are only padding and are ignored when decoding a message) - this is not a flaw. During the Second World War the British cryptographers at Bletchley Park were able to exploit a weakness in the German Enigma codes because they knew that no letter could be encoded as itself and this weakness aided them in cracking the German codes. That weakness cannot be used with the Enigma Morph Encoder. Example#2 Message#2 Dear Jane, I hope you are well. From John. Encoding#2 J1Z66AHAN1 5YID7LQ9B5 72NOA23G1N 3CTFXU0V6K 2WJKD5NKN0 P01E89FMAC In the second example you will notice that the first 31 characters (74%) of Message#2 are identical to Message#1 in Example#1, and yet despite this the Encoding#2 is completely different from Encoding#1, and it would be impossible to look at these two encodings and deduce that the first 74% of Message#2 is identical to Message#1 even though they both used exactly the same Key Phrase and encryption depth - Morphing in action! Often encoding programs or machines (such as the German Enigma machines used during the Second World War) would encode those first 31 characters the same if identical settings where used; this does not happen with the Enigma Morph Encoder. Please note that in the future changes may be made to the Enigma Morph Encoder in order to improve it, when this happens the improved version may not be compatible with older versions. It will be necessary to ensure that all parties using the Enigma Morph Encoder are using the same version. [email protected] Download from:- http://www57.zippyshare.com/v/80072273/file.html

Think Like a Spy? New NY Museum Tests your Skill
 
01:45
(15 Feb 2018) Hello, recruit. Your mission, should you choose to accept it -- learn about the elements of spying, its history, and find out what kind of spy you could be. That's the order of the day at SPYSCAPE, a new attraction opening Friday in Manhattan, where visitors can get a glimpse of spying's past and present, from the code-breaking machines of World War II to the most famous names in espionage and their deeds of derring-do or in some cases, dastardly deception. Visitors can also take a series of tests that gauge everything from their powers of observation to their willingness to take risks, to see what spy role they'd be suited for. (Don't worry, there's no secret agency recruiting station at the exit.) "At Spyscape, we're really here to show you what the real world of spying is like," said Shelby Prichard, chief of staff at SPYSCAPE. "I think a lot of people are going to find that spying involves maybe a little bit more politics and patience than what you see in the movies." The exhibition space in the midtown Manhattan location is divided into different galleries. They focus on specific areas -- encryption, deception, hacking, cyber warfare, intelligence, surveillance and special ops. In each of the galleries, visitors can see artifacts related to that area, like an actual Enigma machine used by the Germans to encrypt their messages during World War II, or masks worn by members of the global hacking group Anonymous with some signed with the code name of the person who wore it. In the surveillance section, part of the exhibition showcases how tools used by governments can also be used by other organizations, by incorporating material from The Associated Press' Pulitzer Prize-winning expose, "Seafood from Slaves." The stories traced how fish caught by slave labor in Southeast Asia ended up on American plates. Reporting it involved using satellite technology to track a cargo ship that was moving the seafood caught by the enslaved men, as well as surveillance of the fish as it was offloaded and moved to other facilities. The exhibit at SPYSCAPE features the tools of the trade like a reporter's notebook and laptop, as well as video from the journalists involved. "We're really focused on showing how every person uses spy skills in their day to day lives. Each of us, in a lot of ways, operates like a spy," Prichard said. The exhibits don't just focus on the past, either _ there's a segment talking about messaging programs like WhatsApp, and how long messages on it will remain encrypted, as well as an area offering tips on how to limit your cyber exposure. An art exhibit is made up of video cameras representing some of the most well-known and widely used social media sites, like Facebook, Twitter and Instagram. The interactive tests that visitors can take to build up their profiles are varied. In one section, they're asked to answer logic puzzles to rate their IQ, while in the deception section they're taught about different physical signs of lying and asked to determine whether someone being questioned is being truthful or not. In the surveillance section, they have a set amount of time to look at a range of screens and answer questions about what they're seeing. The most physical interactive is the Special Ops area, where people take a run through a laser beam maze, trying to hit targets along the way. Several years in the making, SPYSCAPE's advisors and consultants included former spies and members of intelligence agencies, as well as hackers-turned-security consultants.

Cryptography (or cryptology; from Greek κρυπτός, kryptos, "hidden, secret"; and γράφω, gráphō, "I write", or -λογία, -logia, respectively)[1] is the practice and study of hiding information. In modern times, cryptography is considered a branch of both mathematics and computer science, and is affiliated closely with information theory, computer security, and engineering. Cryptography is used in applications present in technologically advanced societies; examples include the security of ATM cards, computer passwords, and electronic commerce, which all depend on cryptography.

Cryptography process seeks to distribute an estimation of basic cryptographic primitives across a number of confluences in order to reduce security assumptions on individual nodes, which establish a level of fault-tolerance opposing to the node alteration. In a progressively networked and distributed communications environment, there are more and more useful situations where the ability to distribute a computation between a number of unlike network intersections is needed. The reason back to the efficiency (separate nodes perform distinct tasks), fault-tolerance (if some nodes are unavailable then others can perform the task) and security (the trust required to perform the task is shared between nodes) that order differently. Hence, this paper aims to describe and review the different research that has done toward text encryption and description in the block cipher. Moreover, this paper suggests a cryptography model in the block cipher.

Better_call_saul Ransomware removal

http://www.anti-spyware-101.com/remov... Better_call_saul Ransomware’s objective is to infect your computer and encrypt your personal files using the RSA-3072 algorithm. This algorithm’s key length is 3072 bits. Thus, it is considered as tough and may be impossible to decrypt. And, as far as we know, currently, no third-party software can decrypt the files once they have been encrypted with it. Our malware researchers have found that this malware is currently being distributed using email spam that contains a malicious self-extracting archive or Word document that has enabled macros that inject this ransomware. Once your computer is infected with Better_call_saul Ransomware, it will change your desktop wallpaper with a message that says “All the important files on your disks were encrypted.” Furthermore, it will disable Internet Explorer and then encrypt various files types capable of carrying personal information (e.g. .docx, .jpg, .gif, .mp4.) After the encryption is complete Better_call_saul Ransomware will add the .better_call_saul file extension and drop a .txt file. Then, it will demand that you pay a ransom for the decryption key. However, you might not receive the key even when you pay the ransom. Therefore, at this point, your only option is to delete Better_call_saul Ransomware using our instructional video and recover your files from external drives and other storage media.
