As already announced at the 26C3 congress, Karsten Nohl, Erik Tews and Ralf-Philipp Weinmann have released details of their cryptanalysis of the proprietary and secret encryption algorithm used with DECT (DECT Standard Cipher, DSC) an encryption commonly used with cordless phones. The analysis was carried out by reverse engineering DECT hardware and descriptions from a patent document. . In their paper titled "Cryptanalysis of the DECT Standard Cipher", the authors describe the analysis and reconstruction of the algorithm, as well as practical ways of calculating the key from recorded key streams within a few hours. A C language implementation of the DSC completes the document. * Cryptanalysis of the DECT Standard CipherPDF, a paper by Karsten Nohl, Erik Tews and Ralf-Philipp Weinmann. Reverse engineer Andrzej Dereszowski closely analysed the malware installed via a PDF document on a customer's system, searching for specific security holes. He found that the freely available Poison Ivy "remote administration tool" had been installed to access infected systems. The link for this article located at H Security is no longer available. .

He's eaten guinea pig in Peru, whale in Japan, and tried insects in Australia. But security guru -- and part-time restaurant critic -- Bruce Schneier mostly steers clear of chain restaurants, which he finds oppressively uniform. When he's not sampling exotic cuisine, Schneier is best known as the developer of the Blowfish and Twofish encryption algorithms and as the bestselling author of Applied Cryptography, which has been called the bible for hackers. He's written other books that examine security and society, and he is a renowned security speaker, blogger, and columnist, as well as a popular media talking head who offers unique views on everything from encryption to post-9/11 security overkill. .

This is the second article in a two-part series looking at cryptographic filesystems. The first article in this series covered the background on cryptographic filesystems from the underlying concepts to some of the mechanics of those systems. This article will cover implementation. The focus will be on implementing the Microsoft's EFS under Windows 2000 and the Linux CryptoAPI. One point to clarify from the first article involves the note that Microsoft's EFS does not support using a password-based symmetric algorithm. This is due to the concern that such schemes are weaker because of their susceptibility to dictionary attacks. While technically accurate, the fact remains that the public portion of the user's X.509v3 certificate (which is used to encrypt the File Encryption Key, or FEK, used by EFS) is used to encrypt the FEK. To decrypt the FEK requires the use of password or passphrase and unless password-based logon is disabled completely this password or passphrase is typically the user's domain password. Microsoft's Windows 2000 product introduced the encrypting file system (EFS) to the Windows product line. While third party add-on encrypting software has been available for some time, EFS was the integration of such a concept into Windows 2000. Under Windows 2000, EFS supports the DESX algorithm only. With Windows XP that encryption algorithm now includes 3DES as well and will eventually include the Advanced Encryption Standard (AES) algorithm.

(Nasdaq: RSAS), the most trusted name in e-security®, today announced that a coordinated team of computer programmers and enthusiasts, known as distributed.net, has solved the RC5-64 Secret-Key Challenge. The distributed.net team solved the challenge in approximately four years, using 331,252 volunteers and their machines. Distributed.net receives a cash prize of $10,000 for solving the challenge. Established in 1997, RSA Laboratories' Secret-Key Challenge is offered to quantify the strength of symmetric encryption algorithms such as DES and the RC5® algorithm with various key sizes. By sponsoring an actual contest, RSA Laboratories helps the industry confirm theoretical estimates, and through this constant evaluation, vendors are motivated to continue to improve their security solutions. The distributed.net consortium utilized the idle time of computers throughout the world to search through the list of all possible 64-bit keys for RSA Security's RC5 algorithm to find the one secret key selected at random by RSA Laboratories that decrypts a given message correctly. RSA Laboratories sponsors a series of cryptographic challenges that allow individuals or groups to attempt to solve various encryption "puzzles" for cash prizes. The RC5-64 Challenge is one of a series of contests held to determine the difficulty of finding a symmetric encryption key by exhaustive search (trial-and-error). Previous contests include the DES Challenge, the RC5-40 Challenge and the RC5-56 Challenge. The link forthis article located at RSA is no longer available. .

IBM says the combination encryption/authentication technique is particularly suited to securing Internet protocols, storage area network protocols, fiber-optic networks and e-business transactions. But analysts say the new technique needs further study. The as-yet-unnamed security algorithm simultaneously encrypts and authenticates messages. That innovation significantly improves the speed of the security process over that of previous approaches, which perform encryption and authentication separately. The new algorithm works using symmetric cryptography, in which the same secret key -- or mathematical code -- is used to encrypt and decrypt a message. Another popular security technique, called public-key cryptography, uses two different keys, one to encrypt and one to decrypt. It is slower but is considered more secure.

IBM claims to have invented a new encryption algorithm which can encrypt and authenticate data in one step. The algorithm takes advantage of parallel processing hardware, to cut in half the time taken to encrypt data. However, the news has failed to impress everyone. IBM says the algorithm could be used to take some of the load off networks, but Bruce Schneier, the founder of Counterpane Technologies, says the speed-up is insignificant in the greater scheme of things. He invoked Moore's Law, commenting: "It's a factor of two. Wait a year, and you get that speed-up for free." The link for this article located at The Register is no longer available.

A year later in 1973 they tried again and got one response, from IBM. Then followed a bit of politicking, but by 1975 DES was born. DES was initially a FIPS (Federal Information Procurement Standard), but was quickly adopted around the world as the de facto standard for encryption. Certified for five years, DES and was checked regularly to make sure it was still strong enough. But in 1996 the US government decided it needed a new standard - an Advanced Encryption Standard or AES. It convened a meeting of cryptographers and industry figures and, in a rare example of democracy in action, it asked them what they wanted in an encryption algorithm.
