摘    要:提出了基于QR分解与二元多项式的密钥建立与分配方案。该方案以二元多项式的计算结果作为无线传感器网络的密钥。二元多项式的其中一个参数由对称矩阵进行QR分解生成,节点部署后交换Q矩阵的行信息再与R矩阵的列信息相乘生成多项式的参数。多项式的另一个参数由各自生成的随机数确定。分析结果表明:该方案可以提高存储效率、网络连通性、抗捕获性能,并能提供额外的通信链路验证。

关 键 词:无线传感器网络  OR分解  多项式  密钥

Abstract:A key establishment and distribution scheme based on QR decomposition and binary polynomial is presented. Computation result of binary polynomial is used as key of wireless sensor networks(WSNs). One of the parameters of the binary polynomial is generated through QR decomposition by symmetric matrix, and after deployment, nodes exchange row information of Q matrix, and then multiply column information of R matrix to generate parameters of polynomial. The other parameter is determined by random numbers produced by each one. The analysis result indicates that this scheme improves storage efficiency, network connectivity, performance of resistance to capture and also provides additional communication link verification.
Keywords:wireless sensor network(WSNs)  QR decomposition  polynomial  key
