摘　　要：针对移动Adhoc网络中GRID协议的广播特性易遭受恶意节点网络攻击的缺点,在安全网格路由协议SGRP的基础上,提出基于优化TESLA的改进方案。采用椭圆曲线数字签名算法完成节点的身份认证,提出通过调整数据包发送顺序的方法减小节点存储开销。对改进协议进行形式化安全分析和性能分析,分析结果表明,该方案相比SGRP具有存储开销小、认证延迟低等优势。To solve the shortcoming of GRID protocol ’s broadcast characteristics in mobile Ad hoc networks that it is vulnerable to malicious node network attacks,an improved scheme based on optimized TESLA on the basis of the SGRP (security GRID routing protocol) was proposed.The Elliptic curve digital signature algorithm was adopted to complete the node ’s identity authentication.The method of reducing the node ’s storage overhead by adjusting the data packet sending order was proposed.The formal security analysis and performance analysis of the improved protocol show that the solution has advantages such as smaller storage overhead and lower authentication delay compared to SGRP.
