....[9] Among these services authentication has been identified as the bottleneck. The compromise of the authentication service breaks down the whole security system, and we cannot proceed to provide the other services without the valid identities of communicating nodes being successfully established [35]. In this report, we focus on the authentication service in ad hoc wireless networks. Our work is based on asymmetric cryptographic techniques, specifically the de facto standard RSA [20] algorithms. Once the authenticated channels are established with proper access control between communicating ....

....communicate with, 4 and route packets for each other. It would be di#cult for each node to maintain a long list of trusted friends, potentially as large as the list contains all nodes in the whole network. Security function sharing has been a very active research area in cryptography research [12, 21, 22, 25, 26, 27, 30, 31, 35]. By distributing the functionality of the centralized CA server among a group of servers, the availability of such services is improved. The single point of failure can also be avoided. Threshold secret sharing [10] serves as a basic primitive for function sharing. The concept of proactive secret ....
