摘要
移动代理是一种软件程序,它漫游在计算机网络中,经过不同的主机代替用户执行一定的任务。它被认为在未来的电子商务中将起到很重要的作用,但安全问题一直是移动代理得到实际应用的一个很大障碍。本文利用二元Merkle树结合Hash函数给出了一个安全的基于Merkle树的移动代理路由协议。相比原有的嵌套签字加密协议,它显著地降低了移动代理主人的计算复杂度。
Mobile agents are software programs that can autonomously migrate from host to host to fulfill their goal- s. It is believed to be playing an important role in future e-commerce systems, but the security problems have been an obstacle for mobile agents to be practical. Based on Merkle trees, a route protection of mobile agents is presented in this paper which reduces the computation cost of the agent owner compared with the protocol based on nested encryp- tions.
