Abstract Authentication is critical to secure communication in Ad hoc networks. This paper discusses the shortcomings of distributed authentication schemes in Ad hoc networks with flat structure and the advantages of adopting clustering structure. A zone authentication scheme is proposed to enhance the efficiency of authentication services with less communication cost. The scheme adopts the clustering structure and divides the networks into independent authentication areas, and fits well in the large Ad hoc networks with better scalability and security.
