基于间隔检测和信誉度的移动Agent安全机制

USING ALTERNATE DETECTION AND REPUTATION FOR MOBILE AGENT SECURITY

移动代理技术是一种新型的分布式网络计算技术,得到广泛的研究。其中的安全性问题,特别是移动代理遭受恶意主机攻击的问题制约了移动代理技术的广泛应用。人们提出了基于参考状态的思想,但目前提出的方法开销都较大,并且只能检测是否存在攻击,而对攻击行为没有采取任何措施。本文综合运用参考状态、间隔检测和信誉度,提出一个新的检测方法:ADR,该方法能对检测到的攻击行为采取矫正措施,并重生移动Agent的正确状态。

As a new technology of distributed network computation, mobile agent becomes a focus of researches. The security problems, especially the problems of the agent being attacked by malicious hosts block the wide use of mobile agent technology. A method based on reference states is suggested, but the overhead of this method is too large, and the attack only been checked while nothing have been done to it. In this paper,based on the reference states,alternate detection and reputation a new method named ADR（ Using alternate detection and reputation for mobile agent security）has been built up. Thismethod can detect and amend the attack,revise the correct states of the mobile agent.
