摘要 针对移动Agent本身的安全性问题,提出了一种基于软件防护的移动Agent保护协议??PDHA(aproto-coltodetectmalicioushosts’attacks),并对该协议进行了安全性分析和性能分析。该协议的核心思想是通过关联密钥链加密机制对移动Agent的数据进行加密,并应用参考状态分析机制对移动Agent的代码、状态进行保护,从而形成一种全面的移动Agent保护协议。实验表明,PDHA协议功能是可以达到的,安全性也更强。 Focusing on the security problems of mobile Agents, a new software protection based protocol-PDHA（a protocol to detect malicious hosts＇ attacks）is proposed. Security analyses and performance analyses for this protocol are surveyed. The key idea of PDHA protocol is to encrypt data of mobile Agents with the mechanism of interrelated keys chains encryption, to protect codes and states of mobiles Agents with the mechanism of reference states analyses, and to present a full protocol for mobile Agent protection. The simulation experiments show the functionality of PDHA protocol can be implemented,and its security is higher.
