Abstract: With the features of convenience and flexibility,Ad hoc network becomes one of the most valuable next-generation networks.However,it has many secure defects because of its lack of inherent infrastructure.The possible secure defects of Ad hoc network were analyzed,and an improved routing protocol with encryption and authentication for Ad hoc network was brought forth,which can prevent both active and passive attacks.The security and efficiency of this protocol were also evaluated.
