基于电子货币技术的移动代理系统安全保护机制的研究

Research on Mobile Agent System Security Mechanism Based on Electronic Currency Technology

移动代理系统提供了一个新的计算方式,程序以软件代理的形式出现,它能在一台主机上停止它的执行,通过移动到另一台主机上恢复执行。随着移动软件混合性的增加,也伴随着对安全的威胁。尤其是对拒绝服务攻击这类消耗系统资源的攻击,目前还没有什么好的方法。提出了将电子货币引入系统来抵御这类攻击,并给出了一个应用模型。

Mobile agent technology offers a new computing paradigm, in which a program, in the form of a software agent, can suspend its execution on a host computer, transfer itself to another agent-enabled host on the network, and resume execution on the new host. As the sophistication of mobile software has increased over time, so do the associated threats to security. Especially, there is no good way to resist such the attacks as denial of service. This paper applies the electronic currency technology to a mobile agent system to resist such attacks and gives a model.
