| 摘 要： | 为高效安全地保护移动代理路由,针对移动代理的选择式路由结构,利用基本加密签字技术,设计了一种基于移动代理的安全选择式路由协议,并对该协议的安全性和计算复杂度进行了分析.结果表明,新协议不仅满足移动代理选择式路由的所有安全性质,而且与已有的基于嵌套加密技术的惟一方案相比,计算复杂度得到了显著的降低,用户和路由主机的计算复杂度均从原来的O(n2)变为O(n);同时,新协议还具有很好的扩展性.

| Abstract: | In order to effectively and securely protect the route of mobile Agents,a securely alternative route protocol based on mobile agents is first presented by means of the atomic encryption and signature.Then,the security and computational complexity of the protocol are analyzed.The results show that the proposed protocol not only sa-tisfies all general security properties for alternative route based on mobile Agents but also reduces the computational complexity from O(n~2) to O(n) in both Agent owners and hosts,as compared with the only method based on the nested encryption,and that the new protocol is of good expansibility. |
