摘　　要：由于移动无线传感器网络支持节点的移动性,使其面临更加复杂的安全性挑战,很难防御一些极具破坏力的攻击,比如节点复制攻击和女巫攻击等。本文提出了在移动异构无线传感器网络模型下一种安全高效的密钥管理方法。所提方法采用椭圆曲线密码学加密算法实现移动节点位置信息到基站的安全上传,以及基于密钥哈希的消息认证码来实现消息源的身份认证。基站则对收集的移动节点位置信息进行统计分析来协助完成固定节点与移动节点间的身份认证及会话密钥建立。实验结果表明,所提方法在密钥建立过程节省了网络资源,同时可有效防御攻击者发起重放攻击、节点复制攻击和女巫攻击等,增强了网络安全性。Mobile wireless sensor networks(MWSNs)support the mobility of nodes,and face more complex security challenges.It is difficult to prevent attackers from launching some extremely destructive attacks,such as node replication attacks and sybil attacks.This paper proposes a safe and efficient key management method under the mobile heterogeneous wireless sensor network model.The proposed method adopts the elliptic curve cryptography encryption algorithm to realize the safe upload of mobile node location information to the base station,and uses the message authentication code based on key hash to realize the identity authentication of the message source.The base station performs statistical analysis on the collected location information of the mobile node to assist in completing the identity authentication and session key establishment between the fixed node and the mobile node.Experimental results show that the proposed method saves network resources during the key establishment process,and can effectively defend against attackers from launching replay attacks,node replication attacks,and sybil attacks,thus enhancing network security.
