Ad Hoc Networks key cluster management solution based on the hash function

On the basis of the characteristics of Ad Hoc Networks, from the perspective of the authentication and key agreement between nodes, this paper puts forward Ad Hoc Networks key cluster management solution based on the hash function. By introducing a clustering technology, this solution reduces the amount of computation and communication between nodes, improves the efficiency of authentication, and achieves effective communication between nodes authentication, digital signatures and other functions.
