Abstract :
We design an architecture of distributed certification authority (MeCA) for wireless mesh networks (WMNs). In MeCA, the secret key and functions of certification authority are distributed over several mesh routers. For secret sharing and redistribution, we develop the fast verifiable share redistribution (FVSR) scheme. MeCA adopts the multicasting based on Ruiz tree, which is optimal in reducing the operation overhead. It can update, revoke, and verify certificates of WMN nodes in a secure and efficient manner. Simulation results show that MeCA does not disclose its secret key even under severe attacks while incurring low overhead compared to other existing schemes in mobile ad hoc networks.
