What is BROADCAST ENCRYPTION? What does BROADCAST ENCRYPTION mean? BROADCAST ENCRYPTION meaning - BROADCAST ENCRYPTION definition - BROADCAST ENCRYPTION 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 Broadcast encryption is the cryptographic problem of delivering encrypted content (e.g. TV programs or data on DVDs) over a broadcast channel in such a way that only qualified users (e.g. subscribers who have paid their fees or DVD players conforming to a specification) can decrypt the content. The challenge arises from the requirement that the set of qualified users can change in each broadcast emission, and therefore revocation of individual users or user groups should be possible using broadcast transmissions, only, and without affecting any remaining users. As efficient revocation is the primary objective of broadcast encryption, solutions are also referred to as revocation schemes. Rather than directly encrypting the content for qualified users, broadcast encryption schemes distribute keying information that allows qualified users to reconstruct the content encryption key whereas revoked users find insufficient information to recover the key. The typical setting considered is that of a unidirectional broadcaster and stateless users (i.e., users do not keep bookmarking of previous messages by the broadcaster), which is especially challenging. In contrast, the scenario where users are supported with a bi-directional communication link with the broadcaster and thus can more easily maintain their state, and where users are not only dynamically revoked but also added (joined), is often referred to as multicast encryption. The problem of practical broadcast encryption has first been formally studied by Amos Fiat and Moni Naor in 1994. Since then, several solutions have been described in the literature, including combinatorial constructions, one-time revocation schemes based on secret sharing techniques, and tree-based constructions. In general, they offer various trade-offs between the increase in the size of the broadcast, the number of keys that each user needs to store, and the feasibility of an unqualified user or a collusion of unqualified users being able to decrypt the content. Luby and Staddon have used a combinatorial approach to study the trade-offs for some general classes of broadcast encryption algorithms. A particularly efficient tree-based construction is the "subset difference" scheme, which is derived from a class of so-called subset cover schemes. The subset difference scheme is notably implemented in the AACS for HD DVD and Blu-ray Disc encryption. A rather simple broadcast encryption scheme is used for the CSS for DVD encryption. The problem of rogue users sharing their decryption keys or the decrypted content with unqualified users is mathematically insoluble. Traitor tracing algorithms aim to minimize the damage by retroactively identifying the user or users who leaked their keys, so that punitive measures, legal or otherwise, may be undertaken. In practice, pay TV systems often employ set-top boxes with tamper-resistant smart cards that impose physical restraints on a user learning their own decryption keys. Some broadcast encryption schemes, such as AACS, also provide tracing capabilities.

Modern symmetric encryption, tweakable PRPs, shuffling, a lecture by Thomas Ristenpart. The topic of the 4th Annual Bar-Ilan Winter School on Cryptography held in January 2014, was Symmetric Encryption in Theory and in Practice. The winter school studied symmetric encryption in theory and in practice, and included a study of the theoretical foundations of symmetric encryption on the one hand, and practical constructions and cryptanalysis on the other hand. As every year, the event organizers were Prof. Yehuda Lindell and Prof. Benny Pinkas, of BIU's Department of Computer Science. This year,the Winter School featured speakers from such institutions as the Royal Holloway at the University of London , and the University of Wisconsin - Madison.

Bitcoin Transaction Details - Part 1
 
15:47
A look at how a transaction is constructed This video is part of a larger online course, "From Barter to Bitcoin: Society, Technology and the Future of Money" run by Prof. Bill Maurer and Prof. Donald J. Patterson In addition to the video on YouTube there is a variety of other content available to students enrolled in the class. "In 2008, a person calling himself or herself or themselves Satoshi Nakamoto released a paper suggesting a system for an anonymous, peer-to-peer alternative money. Bitcoin was born. Although not the first digital currency ever proposed, nor the first challenger to fiat money, bitcoin is the first to have captured the broad imagination of speculators, coders, regulators, criminals and the mass media. This course puts Bitcoin in context: how do we understand money as a social, political and technological phenomenon? From discussions of ancient transactions to the rise of state-issued currencies, we will explore the social and technical aspects of bitcoin, its predecessors and potential successors, and how its features echo aspects of many different historical transaction systems. No prior knowledge of economics or computing is required. There is little academic writing on bitcoin. And this may be the first truly academic class on the topic. We want to put bitcoin in a wider perspective, to reflect on what it means for society, politics and economics, as well as how it helps us think about money both a social and a technical phenomenon. This class is not an advanced seminar on bitcoin--we will not be delving deeply into the inner workings of the system, but instead providing a bird's-eye overview with enough technical detail for you to be able to put media stories, hype and hope around bitcoin in perspective. Similarly, this is not a class in monetary economics--we won't go too deeply into monetary theory or policy, the money supply, or inflation. Instead the class invites you to think more deeply about one of the oldest systems of technology on the planet, and most ubiquitous: money, whether coin, cash, credit card or cryptocurrency, we humans have been making money for most of the past 10,000 years. How we do so in the future is a question bitcoin just maybe helps us answer."

WWII Codebreaking and the First Computers, Malcolm A.H. MacCallum
 
01:08:01
COPERNICUS FESTIVAL, May 6-11, 2014, Kraków http://www.copernicusfestival.com This is the story of why and how the first computers came into being. They were built to assist British codebreaking during World War II, specifically to make possible automated codebreaking of the German teleprinter codes which the British called "Tunny". The story of Tunny is much less well-known than that of the Enigma machines. The General report on "Tunny" was published only in 2000 and some parts of the Tunny story are still classified. It has less Polish connection than Enigma, where three Polish mathematicians played a crucial role by breaking a pre-war version of the Enigma machine: Marian Rejewski, Henryk Zygalski and Jerzy Jerzy Różycki. Like Enigma (where the UK built on the Polish work), the Tunny codes were broken by mathematicians at Bletchley Park, the wartime home of the UK's "Government Code and Cipher School". During the war Bletchley Park was called "Government Communications Headquarters" (GCHQ), so as to give only a vague idea of its purpose. After the war, that became the official name of the UK Government's signals intelligence agency. Because the messages were of high strategic value, the breaking of Tunny was very successful although it decrypted many fewer messages than from Enigma. (27631 Tunny messages were intercepted and 13508 were broken.) As examples, Bletchley decrypted messages direct from Hitler himself in 1944, allowed the British to forewarn the Russians of the German attack around Kursk in July 1943, gave the Allies the German dispositions before D-Day, and showed them the value of the rather slow Italian campaign in tying down German forces. Colossus - machine used for breaking Tunny code - deserves to be called the first computer, although it was not a general purpose computer, but a special purpose cryptographic device. So one has to choose qualifying adjectives a bit carefully. (Many histories say the American ENIAC was the first computer. This just reflects the British ability to keep a secret). Not all features of later machines were present in Colossus: for example it did not have electronically stored programs. But many were: for example, Tommy Flowers introduced the term Arithmetic-Logic Unit (ALU) for the core processing parts and Jack Good's experience with it led him to develop the idea of microprogramming. There is also an interesting comparison of Colossus with the first generation IBM PC. Its first break of a message was on 5 February 1944. By the end of the war there were 10 Colossi. At the end of the war Churchill ordered the destruction of the Colossi. All but two Colossi were broken up and designs destroyed. The remaining two are alleged to have been kept in case the Russians started to use captured German Tunny machines: those Colossi were destroyed around 1960. Information about the machines' existence only emerged in the 1970s due to Brian Randell in particular. Photos were released in 1975, and Flowers was allowed to publish the hardware design of the first Colossus in 1983 (without the explanation of what it was used for). In 1996 the US published the information it had about the machines and, due to Donald Michie, the "General report on Tunny" was published in June 2000. The general report on the Testery's work is still classified. There is a working reconstructed Colossus at Bletchley Park, built by Tony Sale and a team of volunteers. *** Professor Malcolm AH MacCallum is a British cosmologist , astrophysicist and applied mathematician - an Emeritus Professor of Applied Mathematics at the Queen Mary University of London, Deputy President of the International Society on General Relativity and Gravitation, member of the London Mathematical Society, and a chairman of the advisory Board of Mathematics Department at University of York. His field of interests covers most aspects of classical non-Newtonian gravity theory as well as computer algebra applied to differential equations.
The Cryptographic Transformation of Money
 
03:46
The Third Wave of the Informational Transformation of Money has just kicked off. Some 500 years ago money lost its utility per-se, and became data, albeit impressed upon a parchment or a sheet of paper. This was The First Wave. In the 2nd part of the last century money transformed into bitty data nesting in ever faster, inter-communicating computers. This was the 2nd wave. It has brought about dramatic new efficiencies but with it emerged a daunting vulnerability: the bits carried value only, unlike the paper money that was marked with an identifying serial number. This shortcoming invited crowds of criminals and fraudsters that cast a dark shadow on the otherwise shiny vista of online banking, and frictionless payment. In the early years of this century the money bits have been re-invented into per-se digital sequences where value and identity are cryptographically fused together. The 'serial number' feature of the First Wave was re-established. This very step is the onset of the Third Wave, roaring towards us, as we speak. Money, identity-marked, may be paid without the payer and the payee having to mutually identify themselves -- what a relief for our sense of privacy, and what an opening for money launderers . Money where every digital bill is different from all others, may be tethered to its intended purpose: issued for grocery -- you cant gamble with it, Tethered to Alice -- Bob cannot spend it; issued per contract -- can only be spent per contract. This is our chance to build robust financial security, super-efficient globe-spanning payment protocols, ultra tech banking, personal freedom, well-balanced anonymity, and wide-spread prosperity. This course, now offered by The Department of Electrical Engineering and Computer Science at Case Western Reserve University, brings to light the technology and the applications of this Third Wave of the Informational Transformation of Money. Following a brief historic review, we shall discuss the ground reasons for today's ramping financial cyber thefts, and digital heists -- how the 'patching' strategy falls short, as evidenced by our daily headlines: J.P. Morgan, Home Depot, Target, Heartland. But the main focus of this course will be the technology and the functionality of crypto digital money. We shall analyze the various categories, versions, nuances, claims as to what this money can do, and how the underlying cryptography makes it happen. We shall present bold visions for the future of money (e.g. The InterMint). From Bitcoin, through Ripple, DigiCash, M-pesa, and BitMint -- what is out there, how it operates, what does it do. And how does the future look like, staring ahead. This course is designed for two categories of students and participants: computer science students will dive into the mathematical foundation of the technology, and the rest would study the functionality, the novelty, the implementation routes, and the appraisal of the various concepts, about to be sorted out by the marketplace. When this course ends, early December 2015, you will be in the know and ready to surf the rumbling third wave of the informational transformation of money. The 3 credits course is open for graduates and undergraduate students in the university, and to external registrants, against a Certificate of Participation. The course will be broadcast online, allowing registered participants to catch class anywhere on cyberspace. Contact the instructor Gideon Samid: [email protected]

How to establish an encryption key securely with the Quantum Key Distribution scheme ?
 
03:54
BB84 protocol is a quantum key distribution scheme developed by Charles Bennett and Gilles Brassard in 1984. It is the first quantum cryptography protocol. The protocol is provably secure, relying on the quantum property that information gain is only possible at the expense of disturbing the signal if the two states one is trying to distinguish are not orthogonal. It is a method of securely communicating a private key from one party to another for use in one-time pad encryption. So how to establish a random encryption key securely with the Quantum Key Distribution scheme ? Alice creates a random bit of 0 or 1 and then randomly selects one of her two bases (rectilinear or diagonal) to transmit it in. She then prepares a photon polarization state depending both on the bit value and basis. So for example a 0 is encoded in the rectilinear basis (+) as a vertical polarization state, and a 1 is encoded in the diagonal basis (x) as a 135° state. Alice then transmits a single photon in the state specified to Bob, using a quantum channel. This process is then repeated from the random bit stage, with Alice recording the state, basis and time of each photon sent. As Bob does not know the basis the photons were encoded in, all he can do is to select a basis at random to measure in, either rectilinear or diagonal. He does this for each photon he receives, recording the time, measurement basis used and measurement result. After Bob has measured all the photons, he communicates with Alice over the public classical channel. Alice broadcasts the basis each photon was sent in, and Bob the basis each was measured in. They both discard photon measurements (bits) where Bob used a different basis, which is half on average, leaving half the bits as a shared key. Quantum key distribution is only used to produce and distribute a key, not to transmit any message data. This key can then be used with the one-time pad cipher with a secret random key.

Broadcasting Explained - Tensors for Deep Learning and Neural Networks
 
11:20
Tensors are the data structures of deep learning, and broadcasting is one of the most important operations that streamlines neural network programming operations. Over the last couple of videos, we’ve immersed ourselves in tensors, and hopefully now, we have a good understanding of how to work with, transform, and operate on them. If you recall, a couple videos back, I mentioned the term “broadcasting” and said that we would later make use of it to vastly simplify our VGG16 preprocessing code. That’s exactly what we’ll be doing in this video!

How to establish a random encryption key securely with the Quantum Key Distribution scheme ?
 
01:57
BB84 protocol is a quantum key distribution scheme developed by Charles Bennett and Gilles Brassard in 1984. It is the first quantum cryptography protocol. The protocol is provably secure, relying on the quantum property that information gain is only possible at the expense of disturbing the signal if the two states one is trying to distinguish are not orthogonal (see no-cloning theorem). It is usually explained as a method of securely communicating a private key from one party to another for use in one-time pad encryption. Alice creates a random bit of 0 or 1 and then randomly selects one of her two bases (rectilinear or diagonal) to transmit it in. She then prepares a photon polarization state depending both on the bit value and basis. So for example a 0 is encoded in the rectilinear basis (+) as a vertical polarization state, and a 1 is encoded in the diagonal basis (x) as a 135° state. Alice then transmits a single photon in the state specified to Bob, using a quantum channel. This process is then repeated from the random bit stage, with Alice recording the state, basis and time of each photon sent. As Bob does not know the basis the photons were encoded in, all he can do is to select a basis at random to measure in, either rectilinear or diagonal. He does this for each photon he receives, recording the time, measurement basis used and measurement result. After Bob has measured all the photons, he communicates with Alice over the public classical channel. Alice broadcasts the basis each photon was sent in, and Bob the basis each was measured in. They both discard photon measurements (bits) where Bob used a different basis, which is half on average, leaving half the bits as a shared key. Quantum key distribution is only used to produce and distribute a key, not to transmit any message data. This key can then be used with the one-time pad cipher with a secret random key.

Prof. Alex Halderman of University of Michigan at Technion TCE Summer School 2013 Challenging Security Assumptions Part 1 — Challenging Crypto Assumptions: From Cold Boot Attacks to Censorship Resistance The first part of my tutorial will focus on attacks and defenses that are enabled by invalidating the assumptions behind widely deployed cryptography. I'll explain the mechanics behind the cold boot attack, which exploits physical properties of RAM to reveal cryptographic keys and compromise applications such as full disk encryption. We'll use this attack as a vehicle to explore how computing abstractions can conceal important threats. Next, I'll turn to the problem of state-sponsored Internet censorship and show how we can construct a robust censorship resistance scheme by creatively repurposing the TLS cryptographic protocol.

Bitcoin Miner - What is a Bitcoin Miner? Win FREE Bitcoins here: http://win-free-bitcoins.com ... Today !! https://wiki.archlinux.org/index.php/Bitcoin Bitcoin is a decentralized P2P electronic cash system without a central server or trusted parties. Users hold the cryptographic keys to their own money and make transactions directly with each other, with the help of the network to check for double-spending. Bitcoins, usually denoted by BTC (i.e. '144 BTC'), can also be exchanged for traditional currencies like US dollars. The Bitcoin network runs on peer-to-peer networking, digital signatures and cryptographic proof to make and verify transactions. Nodes broadcast transactions to the network, which records them in a public record of all transactions, called the block chain. A block is a record of some or all of the most recent Bitcoin transactions that have not yet been recorded in any prior blocks. In order to preserve the integrity of the block chain, each block in the chain confirms the integrity of the previous one, all the way back to the first one, using hashing. New bitcoins are generated by the network through the process of mining. Mining involves inserting a new block into the current block chain, this is difficult because it requires generating a valid hash (in this case a large integer). A variation in difficulty is achieved by requiring that this integer is below a certain threshold - the data in the block is perturbed by a nonce value, until the data in the block hashes to produce an integer below the threshold - which takes a lot of processing power. The threshold is set by the number of people currently mining for bitcoins so as to achieve a general speed of about 1 block every 10 minutes.

What is Draft Encryption Policy ? [EXPLAINED]
 
03:20
WHAT IS ENCRYPTION ? Encryption is the most effective way to achieve data security. To read an encrypted file, you must have access to a secret key or password that enables you to decrypt it. Unencrypted data is called plain text ; encrypted data is referred to as cipher text. All messaging services like WhatsApp, Viber, Google Chat, Yahoo messenger use encrypted services. For instance, when a WhatsApp message is sent, it’s automatically encrypted or turned into scrambled text, which is then unscrambled for the recipient. This encryption happens automatically using keys at both ends of the conversation and users don’t play a role in this. Banks and e-commerce sites also use encryption to protect financial and private data including passwords. What is the draft encryption policy? According to the terms of the new draft encryption policy, “user shall reproduce the same Plain text and encrypted text pairs using the software/hardware used to produce the encrypted text from the given plain text. All information shall be stored by the concerned B/C business/citizen entity for 90 days from the date of transaction and made available to Law Enforcement Agencies as and when demanded in line with the provisions of the laws of the country.” This means The Government will have access to all encrypted information, including personal emails, messages or even data stored on a private business server, according to the draft of a new encryption policy. The Draft National Encryption Policy wants users to store all encrypted communication for at least 90 days and make it available to security agencies, if required, in text form. It also wants everyone to hand over their encryption keys to the government. What Concerns are Raised ? Almost everyone using the Internet will find themselves in violation of these rules. It is hence detached from the ground realities. This policy has been drafted for the PC era and does not take into consideration the mobile revolution in the country PLEASE WRITE YOUR VIEWS ABOUT THIS POLICY IN THE COMMENT SECTION AND ALSO COMMENT WHETHER THIS POLICY SHOULD BE APPLIED OR NOT.
