基于移动agent的网格环境的安全技术研究

Research on secure technology based on Mobile Agent in Grid network

本文阐述了网格环境的特点、安全需求和移动agent。针对移动agent引入到网格环境中的应用需求所产生的安全问题进行研究,提出了基于移动agent的网格环境的安全体系结构模型。并用一次网格作业执行过程对该模型进行安全性分析,采用数字签名技术保护移动agent的通信过程,实现了单点登录,为多个管理域、多种安全策略,以及主体动态变化的条件下提供网格统一的安全方案。

The article firstly describes the mobile agent, characteristics and the need of security in grid environment. In the paper, research on security problems based on the applications of grid network is also made. We introduced a mobile agent security architecture model based on in Grid network. Use a process of grid work to analysis security problems, and protect the process of mobile agent communication with the help of digital signature. We provide a unified security solution method at last. The method can achieve a single sing-on, and suit an environment with multiple domain management, different security policy and dynamic changes of main conditions.
