摘要
欲阻止恶意主机攻击移动代理,代理中的代码信息和数据信息必须被隐藏起来。同时,还要使它们对于执行环境来说是可访问和可执行的。现有措施大都采用软件方法(如密码技术),但并不足以解决恶意主机问题。一个完全不同的方法就是使用可信赖的且可抵御攻击的JavaCard来保护移动代理。本文讨论用JavaCard保护移动代理的机理,同时给出我们所设计的一个JavaCard的安全模型。
To prevent a malicious host from attacking a mobile agent, the information contained in the code and data of the agent must be hidden. At the same time, it must be accessible and executable for the agent execution environment. Most of the existing measures use software methods, such as encryption techniques, but they are not enough to solve the malicious host problem. A completely different approach is to use trusted and tamper proof JavaCard to protect mobile agents. This paper discusses the mechanism of protecting mobile agents using JavaCard, and gives a security model based on JavaCard.
