The Web Security Password Authentication based the Single-block Hash Function

Abstract

I The paper puts forward the Web security password authentication scheme based on the single-block hash function. The scheme can solve the problem effectively that exists in the traditional password authentication or digital signature in the Web authentication of user's identity to realize the defect. It can resist replay attacks, eavesdropping, modification of messages and common attacks, and low cost, high efficiency, satisfying security and efficient needs of structural features for identifiable authentication in the network service. Generally, MD5 or SHA1 is used. But these algorithms are too cumbersome for the Web authentication of user's identity, and the amount of computation is also too huge. The experimental results show that the scheme guarantees safety at the time, and increases the efficiency of the security authentication.
