| 摘 要： | 针对Ad Hoc网络没有管理中心,资源受限等特点,解决了Ad-Hoc网络面临的新的安全问题,使Ad-Hoc网络得到更广泛的应用.结合基于身份加密和门限秘密共享两个基本理论,提出了一个适用于Ad-Hoc网络、没有管理中心的分布式密钥分发和认证方案.其优点是:减少了运算量,节省了存储空间和带宽,并无需在网络形成之前假设密钥已经分发完毕,从而有效解决了Ad-Hoc网络安全中密钥管理的问题.

| Abstract: | According to infrastructure-less and Low resource availability property of Ad-Hoc network,the solution of new security problems which Ad-Hoc faces is proposed and its practical applications is improved.Using recently developed concepts of identity-based cryptography and threshold cryptography,a distributed key distribution and authentication approach in Ad-Hoc networks is constructed for Ad-Hoc and no infrastructure.The most significant advantage of the scheme lies in the enhancement of security while reducing the communication overhead and resource consumption and saving network bandwidth.The security of the key management in Ad-Hoc network is efficiently resolved. |
