Abstract: This paper presents a new Kerberos assisted Authentication Mechanism in Mobile Ad-hoc Networks named KADH,KADH migrates a number of features from traditional, wired Kerberos environments to the Ad-hoc environment and provides secure extensions to support the more challenging demands of ad-hoc network. Due to the mobility and short range of the nodes, we introduce measures like replication, elections and optional check to ensure maximum connectivity of the clients with the servers and minimize the risk of malicious attacks from within the network.

摘要： 提出了基于Kerberos的移动Ad-hoc网的安全认证机制KADH，它继承了传统Kerberos系统中一些在Ad-hoc网络环境中实用的特性。同时针对结点的移动性和简短性，引入了复制、选择和校验机制确保了连接的安全性，同时使来自网络内部的恶意攻击的危险性降到最低。
