中文摘要：
认证是保证Ad hoc网络通信安全的重要技术。该文针对分布式认证方案分别运用在平面Ad hoc网络和分簇结构中的优缺点进行了比较研究,提出了一种区域认证方案,该方案采用分簇结构,将Ad hoc网络分割为相互独立的认证区域,既减少了网络开销,又增强了认证服务效率,且安全性和可扩展性较好,适用于大规模Ad hoc网络。
英文摘要：
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.
