面向大规模网络应用的移动主体系统安全机制

A Mobile Agent System Security Mechanism for Large Scale Network Applications

从系统整体安全的角度,提出一种面向大规模网络应用的移动主体系统安全机制方案。该方案采用基于混合加密的双向认证技术解决移动主体系统的局部安全问题,通过各级移动主体安全管理平台完成密钥的分配与管理,并对移动主体的迁移进行合理的任务分配与调度,通过任务传递模式解决移动主体的跨网段安全迁移问题,这些措施较为全面的解决了当前移动主体系统的整体安全问题。而且由于采用层次化的系统结构和管理模式,使得该方案非常适合当前面向大规模网络的应用开发。

This paper presents a mobile agent system security mechanism for large scale network applications In this mechanism, we use a bidirectional authentication technology based on mixed encryption to resolve the mobile agent system local security problem. Mobile Agent Security Management Platforms （MASMP） working on different levels is applied to deal with the key distribution and management and control the emigration and task attribution of mobile agents. In order to resolve the problem of mobile agent security transference from one network to another, a task transfer model based on the credibility between two conjoint level MASMPs is designed. All these plans together resolve the mobile agent system security problem well. Because of its hiberarchy system structure and management model, this mechanism is very suit for large scale network applications,
