The Surprising Power of Modern Cryptography
Modern cryptography is surprisingly powerful, yielding capabilities such as secure multi-party computation, computing on encrypted data and hiding secrets in code. Currently, however, some of these advanced abilities are still too inefficient for practical use. This research aims to continue expanding the capabilities of cryptography and its applications and bringing these advanced capabilities closer to practice. In this talk, Stanford PhD. candidate, Mark Zhandry focuses on a particular contribution that addresses both of these objectives: establishing a shared secret key among a group of participants with only a single round of interaction. The first such protocols requires a setup phase, where a central authority determines the parameters for the scheme; unfortunately, this authority can learn the shared group key and must therefore be trusted. He discusses how to remove this setup phase using program obfuscation, though the scheme is very impractical due to the inefficiencies of current obfuscators. He then describes a new technical tool called witness pseudorandom functions and shows how to use this tool in place of obfuscation, resulting in a significantly more efficient protocol.

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.

Broadcasting Explained - Tensors for Deep Learning and Neural Networks
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.

WWII Codebreaking and the First Computers, Malcolm A.H. MacCallum
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.

SpyTools: One-Time Pad
SpyTools is a simple free MacOS application intended to provide some basic tools to hide your secret information with recreational purposes. One-Time Pad encryption refers to the action of processing plaintext with a modular addition according to a secret key of the same length of the text. This encryption process has been proven to be unbreakable if used correctly. SpyTools also allows keys smaller than the length of the text although it should be noticed that the smaller the key is the easier to break the algorithm is also. If you want more information on the algorithm look for: One-Time Pad. Please note that this is a project under development and may and does have some bugs so use this application with caution.

How Bitcoin Works.  (Technical)
Smartcard security for your Bitcoins - http://ledgerwallet.org How does Bitcoin work? This is a question that often causes confusion. Here's a quick explanation! The basics for a new user As a new user, you can get started with Bitcoin without understanding the technical details. Once you have installed a Bitcoin wallet on your computer or mobile phone, it will generate your first Bitcoin address and you can create more whenever you need one. You can disclose your addresses to your friends so that they can pay you or vice versa. In fact, this is pretty similar to how email works, except that Bitcoin addresses should only be used once. Balances - block chain The block chain is a shared public ledger on which the entire Bitcoin network relies. All confirmed transactions are included in the block chain. This way, Bitcoin wallets can calculate their spendable balance and new transactions can be verified to be spending bitcoins that are actually owned by the spender. The integrity and the chronological order of the block chain are enforced with cryptography. Transactions - private keys A transaction is a transfer of value between Bitcoin wallets that gets included in the block chain. Bitcoin wallets keep a secret piece of data called a private key or seed, which is used to sign transactions, providing a mathematical proof that they have come from the owner of the wallet. The signature also prevents the transaction from being altered by anybody once it has been issued. All transactions are broadcast between users and usually begin to be confirmed by the network in the following 10 minutes, through a process called mining. _________________________________________________________ See also bitcoin smartcard ledger wallet nano: https://www.youtube.com/watch?v=5Ss7xnFP9AM _________________________________________________________ Don't forget Subsribe to our channel: https://www.youtube.com/channel/UC-K35rC3yZRiL4kCsua812g _________________________________________________________ This video: http://youtu.be/jFgDfEawAVU

How to establish a random encryption key securely with the Quantum Key Distribution scheme ?
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.
