    基于移动代理的一个鲁棒路由协议

    A Robust Itinerary Protection Based on Mobile Agents

    • 摘要: 移动代理是一种能在异质网络里各计算机间自主迁移的程序.尽管移动代理技术很适合分布式应用,但是安全问题一直是它得到更广泛应用的主要障碍之一.首先对已有的移动代理路由协议进行分析,然后提出了一个基于基本签字基本加密的移动代理路由协议,并对其安全性和计算复杂度进行了详细分析.结果表明,该协议满足路由协议的所有安全性质,而且相比原有的嵌套签字嵌套加密协议,具有更低的计算复杂度.最后,在此基础上提出了一个基于移动代理的鲁棒路由协议,该协议不需要在主机中配备安全的代理创建环境,对路由主机的配置要求不高,具有更广泛的应用性.

       

      Abstract: A mobile agent is regarded as a piece of software roaming the network on behalf of user. Over the recent years, mobile agent technologies have been receiving a great deal of interest. It seems to be the solution to many of the problems in the area of distributed systems. But there are some security issues that have been regarded as the obstacle of application of mobile agent. Route protection is one of them. It is important to protect the routes of a mobile agent if it will visit a list hosts or if it will dispatch some mobile agents to other hosts. In this paper, a secure itinerary protection based on atomic encryptions and atomic signatures is presented which satisfies a set of general security properties for agent route protection. Compared with that based on nested encryptions and nested signature, the protocol reduces the computational cost of route protection. After that, a secure and robust route for mobile agents is given. It can make mobile agents bypass unreachable hosts and continue to finish the task of owner while secure environments existing in hosts to generate mobile agents are not required.
