摘要 基于LU矩阵的密钥预分配方案是无线传感器网络(WSN)进行密钥管理的有效方法,但它存在通信密钥不能正确建立和通信开销大的缺陷。为此,引入了密钥认证机制,提高了密钥协商的安全性和成功的几率;并对密钥协商过程进行优化,如减少发送无关信息。分析表明,相对于原LU方案,带认证的LU方案将密钥协商过程中的平均通信量降低了16.7%。最后给出Sun Spot传感器上的实现方案及其性能分析。 The key pre-distribution based on LU composition of symmetric matrix is an effective approach to the Key management in the Wireless Sensor Networks （WSN）. But there exists the possibility of failing to build the common communication key. To fix this defect and decrease communication traffic, a key pre-distribution scheme with authentication mechanism was proposed, which was based on the LU matrix scheme. Through optimizing the key pre-distribution scheme, we prove that the average communication traffic decreases by 16.7%. At last this scheme＇s implementation in the Sun Spot Sensor and a detailed performance analysis were given out.
