摘　　要：传统局域网密钥共享方法忽略了对异地密钥对协商机制的构建,导致密钥存在被破解风险。为解决上述问题,提出新的无线局域网多安全域间的密钥异地共享方法。通过四元对称多项式将部署节点与节点ID绑定,构建异地密钥对协商机制。将无线局域网多安全域间划分为多个逻辑组,设定位置中心,构建分组部署模型,在不同密钥空间上构建组内节点和组间节点的异地共享密钥,实现密钥高安全度异地共享。仿真结果表明,所提方法能够有效降低破解密钥比例以及密钥共享能耗。Traditionally, some methods ignore the construction of remote key pair agreement mechanism, leading to the risk of cracking keys. Therefore, a method of sharing keys between multiple security domains in WLAN was presented. Firstly, a quaternionic symmetric polynomial was used to blind the deployment nodes to node ID,thus constructing the remote key pair agreement mechanism. Moreover, multiple security domains of WLAN were divided into multiple logical groups, and then the location center was set. Furthermore, a grouping deployment model was constructed. Finally, the remote sharing keys of intra-group node and inter-group node were constructed in different key spaces, thus realizing the remote sharing for keys with high security. Simulation results show that the proposed method can effectively reduce the proportion of cracking keys and the energy consumption of key sharing.
