摘要
分析了当前Ad Hoc网络密钥管理方面的若干方案,根据椭圆曲线密码体制(ECC)可以使用较短的密钥满足较高的安全性需求特点,提出了一种新的基于ECC的分布式密钥管理方案,详细给出了该方案包括主密钥产生、新节点加入和私钥产生等在内的具体实施步骤,并以证书更新服务为例对证书服务性能进行了模拟测试.结果表明,该方案具有较高的安全性,证书服务的有效性和较好的鲁棒性.
We briefly survey the recent works regarding key management of Ad Hoc network,and then analyze elliptic curve cryptography（ECC） that is appropriate for Ad Hoc network mainly owing to its smaller key size and a high security level.Following this lead,we further propose a practical distributed CA-based key management scheme for Ad Hoc network based on ECC,which includes key generation,new node entry and share refreshing.Finally,share refreshing of this scheme is simulated.The simulation proves that the scheme can improve the security,efficiency and robustness of Ad Hoc network.
