无线传感器网络中一种基于共享密钥的节点鉴别机制

Node authentication mechanism based on shared key in wireless sensor network

在无线传感器网络中,信息的传输需要保证通信双方的节点是本次通信的节点,而不是网络中的其他节点或者一些恶意节点,这就需要对通信双方的身份进行身份鉴别。提出了一种基于共享密钥的节点鉴别机制,实现了网内节点间在通信前确认彼此身份的合法性和有效性。分析表明,该方案有效抵御了传感器网络中一些常见的安全威胁,例如女巫攻击等。同时,该方案还具有很强的攻击容忍性。

In wireless sensor network, what is guaranteed in the transmission of information is that the node should be the communication node, rather than the other malicious nodes in the network, which requires the authentication of the identity of the two parties involved. In this paper, a node authentication mechanism based on shared key is given to confirm the legitima- cy and effectiveness of each node before communication. The analysis shows that the program effectively protects against some common security threats in wireless sensor networks such as witch attack and so on. At the same time, the program also has a strong attack tolerance.
