摘要: 移动代理技术是新一代分布处理的关键技术之一,由于其自身所具有的优异特性,已经在很多新兴领域得到了广泛应用。但是安全问题一直是移动代理技术面临的一个很大障碍。文中对Dom ingo J.等提出的一个基于Hash函数碰撞的移动代理路由协议进行了分析,指出其不能抵制路由主机的联合攻击。在此基础上,提出了一个安全的基于Hash函数碰撞的移动代理路由方案。该方案弥补了原有协议的安全缺陷,并对其计算复杂度进行了分析。

Abstract: The characteristics of mobile agents make them ideal for electronic commerce applications in open networks.But the security problems have been an obstacle for mobile agents to be practical.In this paper,Domingo J.’s mobile agents route protections based on Hash functions collision was analyzed.It was pointed out that the protocol could not be against collusion of malicious hosts.Then a secure route protocol of mobile agents based on Hash functions collision was given.The method not only satisfied all security properties but also kept the computational complexity of hosts lower.

Key words: mobile agents, Hash functions collisions, route protocol, computational complexity
