Permabit Uses Secure Hashing Technology in Accordance with Federal Standards.CAMBRIDGE, Mass. -- National Institute of Standards and Technology National Institute of Standards and Technology, governmental agency within the U.S. Dept. of Commerce with the mission of "working with industry to develop and apply technology, measurements, and standards" in the national interest. Reiterates Approval of SHA-256 Hashing Algorithm See hash function. in Light of Recent MD5 Vulnerabilities Permabit(TM), the storage software company that is setting the standard for content addressed storage A storage technique from EMC for content that is in its final form (fixed content). CAS assigns an identifier to the files so they can be accessed no matter where they are located. (CAS), today reiterated that the company uses the SHA-256 hashing algorithm for secure hash-based naming across their entire Permeon software product line. SHA-256, developed by the National Security Agency, is a part of a family of federally recommended security standards (FIPS (Federal Information Processing Standards) A series of publications issed by the U.S. National Institute of Standards and Technology (NIST) that specifies information security guidelines for federal government departments and agencies. 180-2) for information security in archival storage systems. SHA-256 produces a fingerprint fingerprint, an impression of the underside of the end of a finger or thumb, used for identification because the arrangement of ridges in any fingerprint is thought to be unique and permanent with each person (no two persons having the same prints have ever been 256 bits in length, twice as long as that produced by MD5, a prevalent hash function An algorithm that turns a variable-sized amount of text into a fixed-sized output (hash value). Hash functions are used in creating digital signatures, hash tables and short condensations of text for analysis purposes (see hash buster). used in other archiving products. The security of a hash against a random collision increases exponentially with the number of bits, making SHA-256 one hundred trillion trillion times more resistant to an accidental duplication of a fingerprint than MD5. As long ago as 1994, MD5 was considered to have some algorithmic weaknesses. More serious weaknesses in MD5 were demonstrated recently at the CRYPTO 2004 Conference. No vulnerabilities have yet been demonstrated for SHA-256 despite years of analysis by top cryptographers. "Our engineering team determined years ago that SHA-256 was the optimal hashing algorithm for Permeon," stated Jered Floyd, Vice President of Technology at Permabit. "The SHA-2 family of cryptographic hashes contains features that resist attacks which have recently penetrated the security of MD5. We are happy to offer customers a more secure and trusted means for archiving electronic records in accordance with federal standards." About FIPS 180-2 FIPS 180-2 is a compulsory and binding standard for federal agencies. Federal agencies implementing a hashed-based system for information security are required to purchase a system that uses hashes specified in FIPS 180-2. SHA-1 and the stronger hash functions This is a list of hash functions, including cyclic redundancy checks, checksum functions, and cryptographic hash functions. Cyclic redundancy checks
Name Length Type Adler-32 32 bits sum , including SHA-256, are all approved by the National Institute of Standards and Technology (NIST (National Institute of Standards & Technology, Washington, DC, www.nist.gov) The standards-defining agency of the U.S. government, formerly the National Bureau of Standards. It is one of three agencies that fall under the Technology Administration (www.technology. ). Due to advances in technology, NIST plans to phase out SHA-1 and other cryptographic algorithms of similar strength to SHA-1, in favor of the larger hash functions (SHA-224, SHA-256, SHA-384 and SHA-512) by 2010. About Permabit Permabit, the storage software company that is setting the standard for content addressed storage (CAS), enables companies to efficiently and cost-effectively store and retrieve archived electronic content for compliance and reference purposes. By utilizing Permabit's Permeon software, customers can securely retain and quickly access archived records such as email, instant messages, financial statements and office documents, as well as digitized images and media files. Permeon software enables enterprises to comply with even the most stringent government regulations for record retention and verification.
