摘要
移动代理是一种可以在计算机网络中进行自主异步传输的程序,具有很好的应用前景;但移动代理安全性问题的存在,严重阻碍了它在实际中的应用。保护代理免受恶意主机的攻击是移动代理系统独有的安全问题。由于代理必须在主机环境中运行,有效解决该问题比较困难。提出一种基于代码控制流混乱和时间核查技术的移动代理保护方案,该方案在实际网络管理系统中进行了验证,能够有效识别恶意主机,移动代理的保护率达95%以上。
Mobile agent (MA)which has a good application prospect is a program that travels autonomously through a computer network in order to perform some computation or gather information. But security is an important issue for the widespread deployment of mobile agents application,especially the protection of mobile agent avoiding attack from malicious host is a unique security problem. It is difficult to solve this problem because agent is completely exposed in remote host and it is easy to be isolat- ed and attacked by the malicious host. A protection scheme of mobile agent based control flow obfuscation and time checking technology is presented in this paper. The protection scheme is tested in actual network management environment ,which can effectively identify the malicious node. The protection ratio of mobile agent reaches over 95%.
