基于多径路由的安全消息传输协议 MODSMT 的设计

摘要

Existing secure message transmission protocols based on multipath routing in mobile Ad hoc network are difficult to ensure both data availability and confidentiality simultaneously .A modified secure message transfer ( MODSMT) protocol is proposed .What the MODSMT protocol concerns is the data confidentiality and availability .It extends a safe optimisation based on SMT protocol , derives the encryption keys on each path by dynamic computation using the one-way function associated with secret share .After encryption , each encode piece is transmit-ted its encrypted data and its corresponding key parameter separately , and through multipath to its destination node .Simulation demonstrates that the MODSMT protocol can reconcile the availability and confidentiality of data .%移动自组网中现有的基于多径路由的安全消息传输协议在机密性和可用性方面不能同时得到保证。提出一种安全增强的数据传输协议MODSMT（ Modified Secure Message Transmission ）。 MODSMT协议关注的是数据的可用性和机密性，它在SMT协议基础上进行安全优化，每条路径上的加密密钥是通过采用秘密值关联的单向函数动态地计算而得出，编码片段加密后分开传输加密数据和对应密钥参数，并通过多径传输到目的节点。仿真表明，MODSMT协议对数据的可用性和机密性能够同时兼顾。
