概要 Hash functions play an important role in a branch of information secret. The hash algorithm provides the services of information security, authentication, integrity, non-reputation and so on. As the g...rowth of computer technologies, the hash value has been become longer based on the complexity of calculation. It was known to be desirable that the output lengths of hash functions are more than 160 bits. The 1st edition of Hash Function Standard–160 of Korea, namely HAS-160, was published in 1998 and the revised edition was published in 2000. In this paper, we propose the three improved hash functions. First, we propose HAS-256, 384 and 512 that were based on SHA-256, 384 and 512. Second, we propose SHA-V using HAS-V proposed by P.J.Lee [12]. He proposed a new hash function with variable output length. Third, we propose the SHA-V with variable output length and another HAS-longer-version based on RIPEMD-256/320.続きを見る
