Ad hoc networks are a new wireless networking.However, these kinds of networks do not have an underlying fixed infrastructure as well as tend to be vulnerable to a number of attacks due to dynamic network topology and the lack of centralized network management functionality.In this paper, we have proposed a new scheme that will allow two ad hoc nodes to establish a pair-wise shared key on the fly (dynamic) during any stage of the network operations based on cellular automata (CA) rules without requiring the use of on-line key distribution centre.Our proposed scheme consists of a simple, but strong to provide a secure communication against node compromise due to pair-wise key establishment.In addition, the proposed scheme is computationally efficient because it only relies on simple symmetric key cryptography with high randomness, and meets desired levels of high reliability with low storage requirements.
