摘　　要：由于Ad hoc网络的特殊性,基于数字证书的安全机制在其中的应用面临很多困难,其中最大的挑战是:在网络节点无法在线访问CA的情况下,如何实现证书的撤销。在对Ad hoc网络环境下现存的证书撤销机制进行分析后,提出了一种基于单向哈希函数的证书撤销机制,这种机制具有执行效率高、节约网络带宽、计算开销低等优点,非常适用于Ad hoc网络环境。Using security scheme based on digital certificates in Ad hoc network poses many difficulties due to its special nature. Among those difficulties ,the greatest challenge is how to address the certificate revocation issues without the availability of online access to centralized CAs. thie paper analyzes several proposed certificate revocation schemes for Ad lroc networks and presents a certificate revocation scheme based on one-way hash function. Our scheme has such advantages as high efficiency, reduced bandwidth utilization,low computional cost etc, so it is very suitable for Ad hoc networks.
