Abstract: The security of Ad hoc network is a prominent problem. This is exactly the obstacle that the Ad hoc network develops to commerce field. This paper proposes a kind of safety strategy ISAODV on identity-based cryptosystem based on the AODV route algorithm. The identity-based cryptology does not need a certificate in system while the user’s identity such as name, IP address, E-mail address etc can be used as the public key and the public key certificate does not need to be stored. The simulation proves that the ISAODV can simplify the miscellaneous and trivial administration process of the secret key on certificate-based password system.

Key words: Ad hoc network, security, identity-based cryptosystem

摘要： Ad hoc网络安全问题阻碍了其向商业领域的发展。针对该问题，在原有AODV路由算法的基础上，采用基于身份的密码体制设计一种安全路由方案ISAODV。仿真结果表明，在基于身份的密码学系统中，不需要证书，可以使用姓名、IP地址、电子邮件地址等用户标识作为公钥，不需要存储公钥证书，能够简化基于证书的密码系统繁琐的密钥管理过程。
