Cracks In Cryptography: Codebreaking Has Moved On Since Turing's Day. After decades of cracking, the cracks are appearing in cryptography. infobunny, CC BY By Bill Buchanan, Edinburgh Napier University We have always been been intrigued by keeping secrets and uncovering the secrets of others, whether that’s childhood secret messages, or secrets and codebreaking of national importance. With a film, The Imitation Game, reprising the life of Alan Turing and his role in breaking the Nazi’s Enigma cipher of World War II, how does one codebreak, then and now? It’s all in the cipher Imagine that Bob and Alice wish to secretly communicate, and Eve, who wishes to listen in. Here “plain text” refers to the original message, and “cipher text” as the coded message.

Secret messaging, ciphers, and those listening in.Bill Buchanan, Author provided There are two ways of creating the cipher text: In the first case, to read their messages Eve will have to crack the cipher – to work out what method it uses to change plain text to cipher text. Code breaking Enigma Add salt to taste. Future of Cryptography | Techie News. Cryptography has been around since the times of the Roman Empire and has been protecting secret information through the ages. From simple mono alphabetic substitution cipher to some of the most advanced cipher like the Advanced Encryption Algorithm (AES), cryptography has been the primary means of preserving confidentiality, integrity, non-repudiation and authenticity of data.

Most of the algorithms of the old ancient times have been broken and the hashing and encryption algorithms of modern times are proving to be a little more insecure as each day passes by. According to various reports hashing algorithms MD5 and SHA-1 have either been cracked or have started showing weakness and it has been proved by various researchers that the these algorithms might not be capable of providing the security that is desired of them. This may turn out to be far easier as processing power of computers double every two years based on Moore’s law. Cryptography Embedded in Stargate: Universe Hides A Security Lesson. Fascinating, even the math that's way beyond me. And SG:U, yet another show cancelled before it had a chance to succeed or fail on its own. I disagree. They gave them plenty of chances - but the SGU writers were determined to follow the BSG pattern.

It was all so humorless and depressing! Completely unlike SG1 and SGA. The best episodes of the series were the last ones, where we had McKay and O'Niell show up. I mean think about it - the majority of SG shows were a bit like Revenge of the Nerds - the scientists and engineers were the ones who saved everybody. SG:U had a substantially different tone than the earlier offerings in the franchise. Personally, I see it as a matter of taste and style, not an inherent quality difference. I was more upset about them not finishing the SG:A story. While I agree I'd like to add fan spite to this. More than a few fans were livid at the cancellation of SGA to route funding to Universe. I liked SGU. I'll never understand the SGU hate. It was great. TOP SECRET: From Shakespeare to the NSA. A page from the Voynich Manuscript, which has stumped scholars for hundreds of years.

Or, to put it plainly: “Calling all codebreakers.” If you’re ready for something more challenging — much more challenging — than sudokus and crossword puzzles, check out “Decoding the Renaissance,” the new exhibit that opens Tuesday at the Folger Library. Shakespeare noted that uneducated folks “know not how/ To cipher what is writ in learned books,” but these learned books are a cipher to everybody. Among the unfathomable mysteries on display is the Voynich Manuscript. Strange as it might seem among the antique manuscripts at the Shakespeare library, you’ll also find a SIGABA code machine from the NSA’s National Cryptologic Museum. In fact, it’s the curious connection between the Folger and the NSA that inspired curator Bill Sherman to create this show.

He couldn’t have found more fertile ground. Mai Jia: “La criptología convierte a los genios en locos” < literatura espías secretos cifrado censura...

A. Mai Jia es el nombre artísitico de Jiang Benhu (Fuyang, Zhejiang, China, 1964). Fue esta etapa la que le sirvió de inspiración para escribir años más tarde ‘El don‘ (2002, Destino), la primera de sus cuatro novelas, que sale ahora de China tras conseguir unas ventas internas de 15 millones de ejemplares y convertir a su autor en uno de los mayores fenómenos literarios de aquel país.

La historia de ‘El don’ es fundamentalmente la de Rong Jinzhen, un joven huérfano de infancia atormentada y dotado de un don para las matemáticas que le llevará a trabajar para el servicio secreto chino, descifrando mensajes durante la II Guerra Mundial. . – ¿Qué relación existe entre los sueños y los secretos? – Los sueños forman parte también de los secretos. Encryption essential for cyber security: A million reasons to encrypt sensitive data.

Why should all the sensitive data on your computers be encrypted? You can find the answer to that question by Googling these three words: data breach unencrypted. Even a cursory glance at the long list of search results will show you how much trouble organizations can get into when they don’t encrypt sensitive information, particularly personally identifiable information (PII). What kind of trouble does a lack of encryption bring? Well, apart from bad publicity and lost business from customers who decide you can’t be trusted with their data, you could also be looking at a million dollars in fines, possibly more. We’re talking budget-busting costs that could have been avoided by spending just a fraction of that on a basic program of encryption for all company computers. Consider Concentra, a company you probably never heard of before, at least not until April when it reached a $1,725,220 settlement with the OCR.

Fortunately, encryption is no longer the IT pain it used to be. People Want Safe Communications, Not Usable Cryptography. MIT. Security and privacy expert Micah Lee recently described how he helped set up cryptographically protected communications between whistleblower Edward Snowden and the journalists Glenn Greenwald and Laura Poitras, who would share what he had learned about the NSA’s surveillance programs with the world.

Lee’s tale of how the three struggled to master the technology was an urgent reminder of a problem that has bugged me for a while and has implications for anyone who wants to ensure the privacy of personal or professional matters. The cryptographic software we have today hobbles those who try to use it with Rube Goldberg-machine complexity and academic language as dated as a pair of Jordache jeans. Snowden, Poitras, and Greenwald’s tussles with that problem could conceivably have foiled Snowden’s attempts to communicate safely, leaving the world in the dark about U.S. surveillance practices and their effects on our security and privacy. Why is encryption software so horrid to use?

GCHQ launches educational cryptography App. The Cryptoy app by GCHQ aims to encourage children to take up STEM career paths by giving them a fun way to play with cipher systems. The Government Communications Headquarters (GCHQ), the UK's primary intelligence and security organisation, has launched an Android app with which it hopes to encourage children to learn about ciphers and encryption. Dubbed Cryptoy, the GCHQ's latest public software release was created by students on an industrial year placement at the secretive organisation. Originally built to demonstrate various classic encryption techniques at the Cheltenham Science Festival, but is now getting a general release in an effort to encourage more children into science, technology, engineering and mathematics (STEM) careers. 'Building maths and cyber skills in the younger generation is essential for maintaining the cyber security of the UK and growing a vibrant digital economy.

The Criminalization of Cryptography. Introduction to Cryptography. Steven M. Bellovin. .pdf. An Overview of Cryptography. As an aside, the AES selection process managed by NIST was very public. A similar project, the New European Schemes for Signatures, Integrity and Encryption (NESSIE), was designed as an independent project meant to augment the work of NIST by putting out an open call for new cryptographic primitives.

NESSIE ran from about 2000-2003. While several new algorithms were found during the NESSIE process, no new stream cipher survived cryptanalysis. As a result, the ECRYPT Stream Cipher Project (eSTREAM) was created, which has approved a number of new stream ciphers for both software and hardware implementation. Similar — but different — is the Japanese Government Cryptography Research and Evaluation Committees (CRYPTREC) efforts to evaluate algorithms submitted for government and industry applications.

They, too, have approved a number of cipher suites for various applications. A digression: Who invented PKC? 3.3. Let me reiterate that hashes are one-way encryption.

Since the dawn of the Web and ubiquitous free e-mail services over the past two decades, the need to secure personal information online has been evident but often ignored. Last month’s exposure of the U.S. National Security Agency’s PRISM program for collecting data on individuals suspected of plotting terrorist attacks, spying or other forms of malfeasance (pdf) has helped bring privacy issues back into the spotlight.

In fact, the news about PRISM even encouraged some prominent Internet pioneers to condemn the practice and call for renewed efforts among Internet users and their service providers to encrypt more data, to protect it from prying eyes. Vint Cerf, Google’s chief Internet evangelist and co-developer of the TCP/IP communications protocol that makes the Internet tick, recently told The Times of London that computer scientists should devise an anti-snooping solution for the Web using encrypted communication. The catch is that users have to actively set up these programs. A List Of Online Encryption Tools That The NSA Has Already Foiled. Encryption For Beginners In an Era of Total Surveillance.

By @AnonyOdinn If you’ve read the news lately, you’ve pretty much caught the drift of what’s going on. Surveillance is fast spreading to become a universal problem, governments are becoming the largest sponsors and purchasers of intrusive malware, and for all intents and purposes, all so-called “secure” systems are, simply put, not secure – at least not from governmental intrusion, and certainly not from the steady increase of corporate intrusion – a growing problem in a world where the concept of an open and free net is more at risk than ever. The purpose of this simple tutorial is to provide some encryption for beginners. No lies here, the process of setting up software that helps protect your privacy, is not as easy as just using facebook or installing an ordinary browser.

It takes a little (but not much) work. This is not a tutorial on hacking. A couple of points before you proceed. Let’s Begin The Tor Project Perhaps you’ve heard of this. The Tor Project: Tor Tails Start Fresh. Crypto Tools For Everyday Use. .pdf. A Study of advanced encryption tools for data security. .pdf. A (relatively easy to understand) primer on elliptic curve cryptography. Author Nick Sullivan worked for six years at Apple on many of its most important cryptography efforts before recently joining CloudFlare, where he is a systems engineer. He has a degree in mathematics from the University of Waterloo and a Masters in computer science with a concentration in cryptography from the University of Calgary.

This post was originally written for the CloudFlare blog and has been lightly edited to appear on Ars. Readers are reminded that elliptic curve cryptography is a set of algorithms for encrypting and decrypting data and exchanging cryptographic keys. Dual_EC_DRBG, the cryptographic standard suspected of containing a backdoor engineered by the National Security Agency, is a function that uses elliptic curve mathematics to generate a series of random-looking numbers from a seed. This primer comes two months after internationally recognized cryptographers called on peers around the world to adopt ECC to avert a possible "cryptopocalypse. " A toy RSA algorithm.

Properly implemented strong crypto systems are one of the few things that you can rely on.

Unfortunately, endpoint security is so terrifically weak that NSA can frequently find ways around it.— Edward Snowden, answering questions live on the Guardian's website The NSA is the biggest, best funded spy agency the world has ever seen. They spend billions upon billions of dollars each year doing everything they can to vacuum up the digital communications of most humans on this planet that have access to the Internet and and the phone network.

Defending yourself against the NSA, or any other government intelligence agency, is not simple, and it's not something that can be solved just by downloading an app. Table of Contents Threat Model The NSA is a powerful adversary.

Can quantum cryptography work in the real world? By William JacksonOct 28, 2013 Battelle Memorial Institute has built what it claims is the nation’s first production system for quantum distribution of cryptographic keys and announced plans to create a 400-mile link enabling quantum-key distribution (QKD) between Columbus, Ohio, and Washington, D.C., by 2015. The project links two facilities in central Ohio and is a demonstration of the R&D organization’s faith in the ability of the emerging technology to future-proof cryptography threatened by increasingly powerful computers. “Practical QKD systems have existed for about 10 years,” said Don Hayford, director of research at Battelle. But limitations in the range and scalability of the systems have so far restricted their use in this country primarily to research.

Although new in the United States, banks and government agencies in Europe have been using QKD for several years. Not everyone is so sanguine about the current capabilities of QKD.
