基于哈希函数的正弦投影身份认证方案
Sinusoidal Projection Identity Authentication Scheme Based on Hash Function
摘要
Abstract
This paper designs an identity authentication scheme for Wireless Sensor Network(WSN) based on SHA-1 function. By using the feature of multi-mapping, it is widely used in terminal node of WSN which has limited resources. The hash operation is done on the random number sent by the platform and the terminal node's key respectively, the results are integrated to be sinusoidal function variable which has larger value range, the variable is operated by sinusoidal projection, and a set of simpler projection values are obtained. Experiments on MICAz demonstrate that the scheme not only can improve the security of SHA-1, avoid traditional attack, but also can achieve better performance such as less memory space and energy.关键词
