摘　　要：安全问题一直是基于移动代理计算应用中的一个关键问题 .一个基于“承诺”机制的代理交互安全模型主要从理论上针对代理在交互过程中的欺骗行为的防止而提出的 .在检测机制有限的环境中 ,代理的非法性不能得到很好的确定 ,因此需要新的机制来控制代理的恶意行为 .“承诺”机制是指在代理的交互过程中 ,要求代理提供一定数量的利益保证 ,利用该利益保证值可以实现对代理恶意行为的抑制 .通过证明合理的利益保证值的存在性 。Security is the key issue for broadly applying mobile agent technology to distributed computing environment. The promise based security model is theoretically proposed towards preventing the malicious behaviors of agents in the interaction process from the point of view of probability. In the environment with ability limited detecting mechanism, it is hard to determine the illegibility of a malicious agent, so there is the need for extra mechanism preventing the malicious behaviors of agents. Promise based mechanism means that in the agent interaction process, an agent is required to provide some amount of assurance cost so that the malicious behaviors of agents can be restrained. It can be proved that the rational assurance cost is feasible.
