【摘要】 对等计算技术为Internet上海量节点之间计算和信息资源的共享提供了基础平台.对等节点的协作可以有效利用分布于各对等节点上的资源以解决单节点难以完成的复杂任务.然而对等计算环境的动态性、不可预测性等特征也为顺利的协作带来了困难.提出一种基于多移动Agent的对等计算动态协作模型,利用多Agent技术构建P2P平台的协作层,将对等节点之间的协作转换为Agent之间的协作,再通过移动Agent来动态部署针对具体任务的功能组件.还给出了该动态协作模型在密码分析中的应用示范和对比实验数据结果,对该模型的实用价值进行验证.更多还原

【Abstract】 The Peer-to-Peer Computing(P2P)technology is able to provide the foundational platform for computing and information sharing among peers of Internet.The cooperation among peers makes it easy to utilize resources resided on each peer to accomplish complex tasks which are too difficult for any single peer to implement.However,the dynamic and unpredictable P2P environment makes it hard for peers to collaborate successfully.This paper proposes a flexible and dynamic collaboration model of P2P system based on the mobile multi-agent technology.The collaboration layer of P2P is constructed with multi-agents,which converts the collaboration relation from peers to agents.And the functional components for a certain task are deployed by mobile agents dynamically.In the last part of this paper,the cryptanalytic application of the collaboration model and the performance test results are given,which prove the practical value of this model.更多还原
