13 Nov 1997 RIPEMD-160 is a fast cryptographic hash function that is tuned towards soft- ware implementations on 32-bit architectures. It has evolved from the 256-bit extension of MD4, which was introduced in 1990 by Ron Rivest [20, 21]. Its main design feature are two different and independent parallel chains, the

Hash Functions. A hash function is many-to-one; many of the inputs to a hash function map to the same digest. However, for cryptography, a hash function must be one-way. • Given only a digest, it should be computationally infeasible to find a piece of data that produces the digest (pre-image resistant). A collision is a
2 Nov 2007 Abstract. The first designs of cryptographic hash functions date back to the late 1970s; more proposals emerged in the 1980s. During the 1990s, the number of hash function designs grew very quickly, but for many of these proposals security flaws were identified. MD5 and SHA-1 were deployed in an ever
Hash Function. A hash function (in the unrestricted sense) is a function which has, as a minmum, the following two properties compression - maps an input ? of arbitrary finite bitlength, to an output ав. ?. ? of fixed bitlength ¤. ease of computation - given and an input ?, ав. ?. ? is easy to compute.

24 Nov 2008 A hash function h compresses an arbitrary length input message to a fixed length message digest. Such a function should satisfy the following requirements: For any given messge m, the digest h(m) can be computed quickly. Given any possible digest y, it is computationally infeasible to find a message m

А?Жµ is the hash of Е. 2.2. Description of SHA-256. The SHA-256 compression function operates on a 512-bit message block and a 256- bit intermediate hash value. It is essentially a 256-bit block cipher algorithm which encrypts the intermediate hash value using the message block as key. Hence there are two main
