Mutual authentication based hash chain signature scheme in mobile environment
移动环境下的一种基于双向认证的哈希链签名方案*

Digital signature scheme based on public key algorithm was difficult to implement in mobile networks due to the high computation complexity of public key algorithm.So a new mutual authentication-based hash chain signature scheme was proposed.Research indicates this scheme can effectively resist user fraud and external attack.And its performance is greatly improved compared with that of the public key scheme.
