摘要
移动Agent具有迁移计算的特性 ,安全性成为构造运行环境的重要组成部分。分析了Mo bileAgent环境下安全问题的构成和特点 ,并根据它提出了对系统的要求和对所开发的MobileAgent系统JMSAS中的解决方案。将安全模型建立于访问控制模型之上 ,并根据MobileAgent的特点加入了第三方认证体制。在安全机制的设计中围绕Agent的两种状态———运行态和迁移态进行讨论 ,对主要部件和协议做了详细的介绍。
Security is an important part in the construction of the software that runs the environment during the calculation of the itinerary of Mobile Agents. The formation and characteristics of the security for the environment under a Mobile Agent are analyzed. This analysis of the system is used to find out the requirements and the solutions to develop security for JMSAS in a Mobile Agent. The security model is built before the visit control model. In the meantime, the third party confirmation system is introduced according to the characteristics of the Mobile Agent. Both running state and the itinerary state of the Agent are to be considered during the design of its security mechanism.
