中文摘要：

在基于哈希函数的签名方案的基础上,提出了一种新的基于双向认证的哈希链签名方案,能够防止用户双方作弊及外部攻击。并对其签名和认证的速度进行了实验测试,相对于基于公钥算法的数字签名方案,该方案的执行速度有明显提高。

英文摘要：

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.
