CAST-256 - Wikipedia, the free encyclopedia In cryptography, CAST-256 (or CAST6) is a block cipher published in June 1998 and submitted as a candidate for the Advanced Encryption Standard (AES). It is an extension of an earlier cipher, CAST-128; both were designed according to the "CAST" design methodology invented by Carlisle Adams and Stafford Tavares. Acceptable key sizes are 128, 160, 192, 224 or 256 bits. en.wikipedia.org /wiki/CAST-256   (179 words)

CAST-128 - Wikipedia, the free encyclopedia The algorithm was created in 1996 by Carlisle Adams and Stafford Tavares using the CAST design procedure; another member of the CAST family of ciphers, CAST-256 (a former AES candidate) was derived from CAST-128. According to some sources, the "CAST" name is based on the initials of its inventors, though Bruce Schneier reports the authors' claim that "the name should conjure up images of randomness" (Schneier, 1996). Although Entrust holds a patent on the CAST design procedure, CAST-128 is available worldwide on a royalty-free basis for commercial and non-commercial uses. en.wikipedia.org /wiki/CAST-128   (289 words)

Business Wire: Entrust Technologies' CAST-256 Encryption Algorithm Accepted as Official Candidate for Advanced ... The original CAST design procedure, engineered to deliver high software performance on general-purpose computers, was co-invented in 1988-89 by Carlisle Adams, then pursuing graduate studies at Queen's University in Kingston, Canada, and his thesis supervisor Dr. Stafford Tavares. "The CAST design procedure combines security, flexibility, speed and simplicity within a solid theoretical framework that incorporates design principles which are generally agreed to be cryptographically important among the leading researchers in the cryptologic community," said Dr. Carlisle Adams, Senior Cryptographer, Entrust Technologies. CAST is several times faster than DES in software and can be tuned to provide even higher performance, if required, in applications such as session-based encryption or other areas where efficient bulk encryption is required. www.findarticles.com /p/articles/mi_m0EIN/is_1998_August_4/ai_20982634   (804 words)

Cryptographic Algorithms CAST is patented by Entrust Technologies, which has generously released it for free use. The first version of LOKI to be released was broken by differential cryptanalysis and was shown to have an 8-bit complementation property (this means that the number of keys that need to be searched in a brute force attack is reduced by 256). While bitslicing is generally used to encrypt multiple blocks in parallel, the designers of Serpent have embraced the technique of bitslicing and incorporated it into the design of the algorithm itself. www.baltsoft.com /files/ee/Cryptographic_Algorithms.htm   (2820 words)

Zeke's Gallery: More on Steve Kurtz The U.S. District Attorney attempted to cast the issue as one of public health and safety in a public press conference called without the knowledge of either defendant's lawyers, thus eliminating the chance of rebuttal. During the conference, parts of which were broadcast on local Buffalo news channels, U.S. Attorney William Hochul and U.S. District Attorney Michael Battle repeatedly alluded to "dangerous" and "bio-hazardous material," even though the charges have nothing to do with such issues, and scientists universally regard the materials in question as safe. Many believe the attempt to cast the $256 technicality as a public health and safety issue is a face-saving measure by the government, which has already expended an enormous amount of time and money in their fruitless pursuit of this case. zekesgallery.blogspot.com /2004/06/more-on-steve-kurtz.html   (679 words)

Standard Cryptographic Algorithm Naming The "provable security" referred to in the paper is in the sense of a proven reduction from predicting the keystream generator, to breaking Rijndael-256 as a one-way function. The design procedure that was used to obtain the CAST S-boxes is patented by Entrust Technologies, Inc.. Dumping several times more than 256 bytes from the output stream (twice or three times this number) appears to be just as reasonable a precaution. www.users.zetnet.co.uk /hopwood/crypto/scan/cs.html   (6436 words)

CAST   (Site not responding. Last check: 2007-09-05) 128, 160, 192, 224 or 256 bits (CAST-256). The CAST encryption algorithm is a DES-like Substitution-Permutation Network (SPN) cryptosystem which appears to have good resistance to differential cryptanalysis, linear cryptanalysis, and related-key cryptanalysis. This cipher also possesses a number of other desirable cryptographic properties, including avalanche, Strict Avalanche Criterion (SAC), Bit Independence Criterion (BIC), no complementation property, and an absence of weak and semi-weak keys. www.networksorcery.com /enp/data/cast.htm   (98 words)

Continuing Investigation of Steve Kurtz   (Site not responding.

The charges concern technicalities of how Ferrell helped Kurtz to obtain $256 worth of harmless bacteria for one of Kurtz's art projects. The laws under which the indictments were obtained—Title 18, United States Code, sections 1341 and 1343, covering mail and wire fraud—are normally used against those defrauding others of money or property, as in telemarketing schemes. www.ncac.org /issues/kurtzindictment.htm   (680 words)
