RESEARCH AND DESIGN OF A WSN SMALL DATA DISTRIBUTION SECURITY SCHEME

提出一种无线传感器网络WSN(Wireless Sensor Network)小数据分发安全的方案,用以解决WSN中节点相关参数更新的安全问题。该方案使用基于TCP SYN-Cookie改进的双向认证技术,密钥协商以及LED轻量级加密算法,实现普通节点和簇头节点之间通信的安全。该方案和同量级方案在安全性、计算效率以及存储效率方面进行比较,安全性和效率都更高。并且,该方案能够使WSN中小数据分发的安全问题得到更加有效的解决,使WSN能够抵御DDOS攻击以及中间人攻击。

This paper presented a scheme of small data distribution security in Wireless Sensor Network( WSN) to solve the security problem of node-related parameter update in WSN. This scheme used the improved two-way authentication technology based on TCP SYN-Cookie,key agreement and LED lightweight encryption algorithm to realize the communication between common node and cluster head node. By analyzing the security of the scheme,the efficiency of the calculation and the efficiency of the storage,the scheme had higher security and efficiency than other similar programs. Moreover,the solution could effectively solve the security problem of distributing the small data in the WSN,so that the WSN could resist DDOS attacks and man-in-the-middle attacks.
