摘要
针对文献[1]提出的使用源主机检测主机执行移动代理时间的安全协议的不足,进行了改进。通过运行在可信主机上的协作Agent,限制移动Agent在主机上的运行时间,设计了一个安全有效的协议,以防止恶意主机对Agent代码和数据的篡改以及拒绝服务攻击。
O.Esparza introduced a protocol of using the origin host to verify if there are incoherences in the execution or transmission times in the hosts. This paper presents an improved protocol to offset the inadequacies of O,Esparza＇s protocol. By using the perfect cooperation of a sedentary agent running on a trusted third host, it aims to design a new secure protocol, which can detect manipulation attacks performed during the agent＇s execution and the attack of denial of service.
