The newly improved protocol needs no clock synchronization mechanism between principals and can be efficiently implemented by using an efficient evidence management scheme called evidence chaining.

新的改进使协议不需要时钟同步机制，还能通过使用一种称为证据链的证据管理机制使协议实现效率更高。

Experimental results show that, this protocol can effectively avoid the problem of clock synchronization when only use timestamp, and good anti-replay attack capacity.

实验结果表明，该协议能避免单纯采用时间戳所带来的时钟同步问题，具有较好的抗重放攻击能力。
