Unboxing The White-Box: Practical Attacks Against Obfuscated Ciphers
 
56:50
by Eloi Sanfelix & Job de Haas & Cristofaro Mune White-Box Cryptography (WBC) aims to provide software implementations of cryptographic algorithms that are resistant against an attacker with full access to the internals. Therefore, the key must remain secure even if the attacker is able to inspect and modify the execution of the cryptographic algorithm. This is often referred to as "security in the White-Box context." In a vanilla implementation of a cryptographic algorithm, access to intermediate results directly leads to extraction of the key. To achieve security in the white-box context, data encoding schemes and strong obfuscation are typically applied. This type of implementation is commonly seen in DRM systems, and is currently gaining momentum in the mobile payment market. Assessing the security of WBC implementations is a challenge both for evaluators and for WBC designers, as it often requires a powerful mix of reverse engineering and applied cryptanalysis skills. In this presentation, we show how attacks typically used to attack hardware cryptosystems can be ported to the white-box settings. We will introduce generic yet practical attacks on WBC implementations of the TDES and AES ciphers. Additionally, we will analyze the requirements for each attack and discuss potential countermeasures. We have applied these attacks to recover cryptographic keys from commercial as well as academic implementations. During the presentation, we will demonstrate several attacks on open source WBC implementations using custom tools. If you are tasked with evaluating the attack resistance of a WBC-based solution, this presentation will provide a better understanding of what White-Box Cryptography is and how to evaluate its robustness against different key extraction attacks. If you are a WBC designer, you will obtain a better understanding of what the most common weak points of such schemes are. Our results highlight the importance of evaluating WBC implementations with respect to these generic attacks in order to provide correct judgment about their level of security.

What is VISUAL CRYPTOGRAPHY? What does VISUAL CRYPTOGRAPHY mean? VISUAL CRYPTOGRAPHY meaning - VISUAL CRYPTOGRAPHY definition - VISUAL CRYPTOGRAPHY explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Visual cryptography is a cryptographic technique which allows visual information (pictures, text, etc.) to be encrypted in such a way that decryption becomes the job of the person to decrypt via sight reading. One of the best-known techniques has been credited to Moni Naor and Adi Shamir, who developed it in 1994. They demonstrated a visual secret sharing scheme, where an image was broken up into n shares so that only someone with all n shares could decrypt the image, while any n - 1 shares revealed no information about the original image. Each share was printed on a separate transparency, and decryption was performed by overlaying the shares. When all n shares were overlaid, the original image would appear. There are several generalizations of the basic scheme including k-out-of-n visual cryptography. Using a similar idea, transparencies can be used to implement a one-time pad encryption, where one transparency is a shared random pad, and another transparency acts as the ciphertext. Normally, there is an expansion of space requirement in visual cryptography. But if one of the two shares is structured recursively, the efficiency of visual cryptography can be increased to 100%. Some antecedents of visual cryptography are in patents from the 1960s. Other antecedents are in the work on perception and secure communication. Visual cryptography can be used to protect biometric templates in which decryption does not require any complex computations.

Top 10 Cyber Security Facts | Cryptography, Data Breach, Decryption, Firewall, Crudware, Honeypot
 
04:05
Top 10 facts about Cyber Security On number 10 there is Cryptography A Cryptography involves creating written or generated codes that allows information to be kept secret. Cryptography converts data into a format that is unreadable for an unauthorized user, allowing it to be transmitted without anyone decoding it back into a readable format, thus compromising the data. On number 9 there is Data Breach A data breach is an incident that involves the unauthorized or illegal viewing, access or retrieval of data by an individual, application or service. It is a type of security breach specifically designed to steal and/or publish data to an unsecured or illegal location. A data breach is also known as a data spill or data leak. On number 8 there is Backdoor A backdoor is a technique in which a system security mechanism is bypassed undetectably to access a computer or its data. The backdoor access method is sometimes written by the programmer who develops a program. A backdoor is also known as a trapdoor. On number 7 there is Encryption Encryption is the process using an algorithm for tagging information to make it unreadable for unauthorized users. This cryptographic method protects sensitive data such as credit card numbers by encoding and transforming information into unreadable cipher text. This encoded data may only be decrypted or made readable with a key. Symmetric-key and asymmetric-key are the two primary types of encryption. On number 6 there is honeypot A honeypot is a decoy computer system for trapping hackers or tracking unconventional or new hacking methods. Honeypots are designed to purposely engage and deceive hackers and identify malicious activities performed over the Internet. Multiple honeypots can be set on a network to form a honeynet. On number 5 there is Crudware A Crudware is a type of freeware and software marketing tactic in which large quantities of beta, trial, freeware or limited software versions are freely distributed or promoted on websites, social networks and related online communities. Crudware is used to lure and motivate prospective customers into purchasing a complete or paid version of the software, or even malware. On number 4 there is Vulnerability A vulnerability is a cyber-security term that refers to a flaw in a system that can leave it open to attack. Vulnerability may also refer to any type of weakness in a computer system itself, in a set of procedures, or in anything that leaves information security exposed to a threat. On number 3 there is Hacktivism A Hacktivism is the act of hacking a website or computer network in an effort to convey a social or political message. The person who carries out the act of hacktivism is known as a hacktivist. On number 2 there is Firewall A firewall is software used to maintain the security of a private network. Firewalls block unauthorized access to or from private networks and are often employed to prevent unauthorized Web users or illicit software from gaining access to private networks connected to the Internet. A firewall may be implemented using hardware, software, or a combination of both. On number 1 there is Decryption A Decryption is the process of transforming data that has been rendered unreadable through encryption back to its unencrypted form. In decryption, the system extracts and converts the garbled data and transforms it into texts and images that are easily understood not only by the reader but also by the system. Decryption may be accomplished manually or automatically. It may also be performed with a set of keys or passwords. ▶DONT CLICK THIS - https://goo.gl/p9DRXs

Crypto Defenses for Real-World System Threats - Kenn White - Ann Arbor
 
01:36:58
Modern encryption techniques provide several important security properties, well known to most practitioners. Or are they? What are in fact the guarantees of, say, HTTPS TLS cipher suites using authenticated encryption, IPSec vs. SSL VPNs, Property Preserving Encryption, or token vaults? We live in an era of embedded Hardware Security Modules that cost less than $1 in volume, and countless options now exist for encrypting streaming network data, files, volumes, and even entire databases. Let's take a deep dive into the edge of developed practice to discuss real-world threat scenarios to public cloud and IoT data, and look closely at how we can address specific technical risks with our current encryption toolkits. Advanced math not required. Bio: Kenneth White is a security researcher whose work focuses on networks and global systems. He is co-director of the Open Crypto Audit Project (OCAP), currently managing a large-scale audit of OpenSSL on behalf of the Linux Foundation's Core Infrastructure Initiative.

Welcome to Indian Statistical Institute (ISI), a unique P. C. Mahalanobish institution devoted to the research, teaching and application of statistics, natural sciences and social sciences. Founded by Professor P.C. Mahalanobis in Kolkata on 17th December, 1931, the institute gained the status of an Institution of National Importance by an act of the Indian Parliament in 1959. The Headquarters of ISI is located in the northern fringe of the metropolis of Kolkata. Additionally, there are four centres located in Delhi, Bangalore, Chennai and Tezpur. Research in Statistics and related disciplines is the primary activity of the Institute. Teaching activities are undertaken mainly in Kolkata, Delhi and Bangalore. Offices of the Institute located in several other cities in India are primarily engaged in projects and consultancy in Statistical Quality Control and Operations Research'. Indian Statistical Institute (ISI) is an academic institute of national importance as recognised by a 1959 act of the Indian parliament. It grew out of the Statistical Laboratory set up by Prasanta Chandra Mahalanobis in Presidency College, Kolkata. Established in 1931, this public university of India is one of the oldest and most prestigious institutions focused on statistics, and its early reputation led it to being adopted as a model for the first US institute of Statistics set up at the Research Triangle, North Carolina by Gertrude Mary Cox. Mahalanobis, the founder of ISI, was deeply influenced by wisdom and guidance of Rabindranath Tagore and Brajendranath Seal. Under his leadership, the institute initiated and promoted the interaction of Statistics with natural and social sciences to advance the role of Statistics as a key technology by explicating the twin aspects – its general applicability and its dependence on other disciplines for its own development. The institute is now considered as one of the foremost centres in the world for training and research in Computer science, Statistics, Quantitative Economics and related sciences. ISI has its headquarters in Baranagar, a suburb of Kolkata, West Bengal. It has four subsidiary centres focused in academics at Delhi, Bangalore, Chennai and Tezpur, and a branch at Giridih. In addition, the Institute has a network of units of Statistical Quality Control and Operations Research at Vadodara, Coimbatore, Hyderabad, Mumbai and Pune engaged in guiding the industries, within and outside India, in developing the most up–to–date quality management systems and solving critical problems of quality, reliability and productivity. Primary activities of ISI are research and training of Statistics, development of theoretical Statistics and its applications in various natural and social sciences. Originally affiliated with the University of Calcutta, the institute was declared an institute of national importance in 1959, through an act of Indian parliament, Indian Statistical Institute act, 1959. ISI functions under the Ministry of Statistics and Programme Implementation (MOSPI) of the Government of India.Key areas of expertise of ISI are Computer science, Statistics, Mathematics, Mathematical economics, Operations Research and Information Science and it is one of the few research oriented Indian schools offering courses at both the undergraduate and graduate level.

DEF CON 23 - Ryan Castellucci - Cracking CryptoCurrency Brainwallets
 
42:49
Imagine a bank that, by design, made everyone's password hashes and balances public. No two-factor authentication, no backsies on transfers. Welcome to "brainwallets", a way for truly paranoid cryptocurrency users to wager their fortunes on their ability to choose a good password or passphrase. Over the last decade, we've seen the same story play out dozens of times - a website is broken into, the user database is posted online, and most of the password hashes are cracked. Computers are now able make millions, billions or even trillions of guesses per second. Every eight character password you can type on a standard keyboard and every combination of five common english words could be tried in less than a day by today's botnets. Can people come up with passphrases able to stand up to that when money is on the line? Let's find out. For this talk, I will be releasing my high speed brainwallet cracker, "Brainflayer". I'll cover a history of brainwallets, safer passphrase-based wallet generation, passphrase security, in-the-wild cracking activity, and how I accidently stole 250 Bitcoins (and tracked down the owner to give them back). Ryan Castellucci has been interested in cryptography since childhood when his parents gave him a copy of "Codes, Ciphers and Secret Writing". He soon learned to program and wrote a tool to crack simple substitution ciphers. More recently, he co-spoke with Dan Kaminsky at DEF CON 22 and was a finalist in the 2014 Underhanded Crypto Contest. For his day job at White Ops, he finds new and exciting ways to tease out the subtle differences between bots and human-controlled web browsers.
