摘要
由于无线传感器网络的许多特性,使其安全方案必须兼顾安全与性能两方面的因素。由此提出了一种全新的分组加密安全协议,以线性同余发生器LCG为基础,适合构建可靠安全并资源有限的无线传感器网络。具体来说,分组加密是给原始数据包加入LCG生成的随机噪声和随机序列,以此来提高安全性。而且这种方式能够满足无线传感器网络的安全需求,并且开销低、效率高。
Because of their own characteristics,Wireless sensor networks should take account of both the security and the system performance.In this paper,we propose a new block cipher security protocol,which based on a Linear Congruential Generator(LCG).The security protocol is suitable for constructing reliable,safe and resource-constrained Wireless sensor networks.Specifically,our proposed block cipher is to add LCG random noise and random sequence to the original data messages,in order to improve security.Moreover,this approach based on our proposed can satisfy the security requirements of Wireless sensor networks,low overhead and high efficiency.
