SECURITY OF CRYPTOGRAPHIC ALGORITHM SHA AND MD5 (Pages : 28 - 33)

Cryptography is a system of secret communication to improve the security of information. There are three kinds of cryptographic algorithm. They are hash functions algorithm, secret key functions algorithm and public key functions algorithm. Hash functions algorithms such as MD4, MD5, SHA, RIPEMD, TIGER, RIPEMD-160 are most widely used in commercial as well as defense applications. Since their design paradigm is based on “trial-and-error” process, they need to have good cryptanalysis effort. Among hash algorithms, SHA and MD5 are most popular. In this paper, a postmortem analysis has been done on two popular hash functions cryptographic algorithms SHA and MD5. This paper shows the security measure and different kinds of attacks on these two algorithms.Download
