摘要 提出了一种基于椭圆曲线密码的传感网络密钥管理体制.该体制使用公钥密码技术来保护会话密钥协商,保证了网络的安全性、连通性和可扩展性.另一方面,在每次密钥协商时,将DH(Diffie-Hellman)交换的私钥重用作为签名所需要的一次性随机数k,实现了数字签名和密钥交换的集成.同时,响应方发送的第三条消息不使用签名而是简单地用带密钥哈希消息认证码来认证,使得双方的通信数据量和计算量大大减少,从而提高了体制的效率,满足了传感网络对计算能力和存储量的苛刻要求. With the development of related technology, public key cryptosystem can also be utilized to build the security mechanism of WSN. With the integration of signature and key exchange of ECC, we propose an efficient key management scheme for WSN. An analysis shows it is of high security and efficiency. It can also guarantee the connectivity and flexibility of the network. Moreover, it meets the requirement of the limited computation and storage resource of the WSN node.
