摘　　要：无线信道具有开放性,节点间建立配对密钥是无线传感器网络安全通信的基础。在大部分基于身份加密(I-dentity-Based Encryption,IBE)的传感器网络密钥协商方案中,使用双线对运算建立配对密钥,能耗高且耗时长。基于BNN-IBS身份签名提出了一个新的无线传感器网络密钥协商方案,节点通过Diffie-Hellman协议建立配对密钥,所需的密钥参数通过广播获得。与基于IBE的传感器网络密钥协商方案(IBE-based Key Agreement Scheme,IBEKAS)进行量化比较,结果表明本方案不仅提供了与IBEKAS同层次的安全性与可扩展性,且在能耗与时耗方面具有较明显的优势。For the openness of wireless channel,establishing pairwise key between sensor nodes is the basis of the secure communication in wireless sensor networks.In most of existing IBE-based key agreement schemes,the pairwise key was established using Tate pairing with high energy consuming and time consuming.In this paper,authors proposed a key agreement scheme based on BNN-IBS signature,sensors broadcast the parameters required for establishing pairwise key and compute the key using Diffie-Hellman key exchange technology.Compared with the IBE-based key agreement scheme,the proposed scheme has patent advantages in energy consuming and time consuming with the same security and scalability.
