摘　　要：AdHoc网络是一种多跳自适应网络,特点是拓扑结构动态变化、移动终端具有局限性、无线信道容易受到攻击等。基于Ad Hoc网络的特点,在Ad Hoc网络多播技术中提出了两种不同的基于安全锁的密钥管理方案,这两种方案分别利用了拉格朗日插值法和B-样条函数插值法。在Ad Hoc网络多播中使用安全锁技术进行密钥管理,有下列优势:①进行多播的发送方发送一个信息包时只需发送一次;②解密算法效率较高;③每个节点只需保存少量的密钥。Ad hoc network is a multi-hop, self-adaptive network. Its topology structure changes dynamically. The end-points and the wireless channel are constrained. Two kinds of key management schemes were given based on security lock in ad hoc network, one is based on Lagrange Interpolation formula and the other is based on B-stripe interpolation formula. There are the following predominance to use the security lock technology in ad hoc multicast technology： 1. The sender can send a packet one time when it is multicasted; 2. The decryption algorithm has a better performance; 3. Every node can save very few keys.
