Ad Hoc network is a kind of independent of any fixed infrastructure, there is no central control node, a new type of wireless mobile network limited computing resources. Based on ECC (elliptic curves cryptography), proposed a new suitable for Ad Hoc network has a password authentication and Shared password in the evolution of various key agreement scheme. A function is as a Shared password authentication information of the mobile node key, another feature is the interaction between mobile node as the symmetric key encryption information. Shared password evolutionary mechanism to ensure every time authentication node key and session key agreement password the freshness and safety, which both reduces the burden of computation and storage of mobile node, and implements the mobile node between key authentication and information encryption. The new scheme can prevent middle attack, replay attack, key independent and forward security and other security features.
