Security support is a must for ad hoc networks.Especially in dynamic topology, key update is essential to provide security. Also it need to protect node's identity in wireless environment. However, existing key update or key agreement scheme for ad hoc networks doesn't consider these issues together. This paper propose ID-based private key update scheme and ID-based key agreement scheme in mobile ad hoc networks. These schemes are suitable for the infrastructureless mobile ad hoc networks.
