摘要
文章提出了一种基于密钥预分配无线传感器网络中的加密方案,该方案在加密过程中使用了计数器和消息认证码,从而较好地满足了传感器网络的安全需求。同时,考虑到传感器节点资源有限的特点,方案中相关的协议和算法都比较简单,并完全避开了代价昂贵的公钥运算,从而使得方案的计算、存储和通信开销都比较小,执行效率大大提高。
This paper proposes an encryption scheme based on key predistribution for wireless sensor network (WSN), which fulfills perfectly all the security requirements in WSN using the counter and message authentication code during the encryption process. Furthermore, the related protocols or algorithms are very simple and no expensive public-key operation is required in view of resource-starved sensor nodes, which minimizes the storage, computation, communication overhead and improves the efficiency of our scheme.
