摘要
无线传感器网络的数据传输存在着诸多安全威胁。为了满足无线传感器网络对于信息源身份认证的需求,在TelosB平台上外接Cyclone II-EP2C5T144最小系统板,设计并实现了基于ECC加密算法的身份认证系统。对ECC模块的底层运算单元采用并行处理的方法进行了优化设计。实验结果表明,优化设计后的认证速度相比传统设计方法提高了近一倍。
There are many security threats in data transmission o f wireless Sensor Networks. In order to meet the requirements of Wireless Sensor Network for data origin authentication, the Ellipse Curve Cryptography authentication scheme is implemented on TelosB hardware nodes by external CycloneII- EP2C5T 144 System. The basic arithmetic unit o f ECC is optimized by using parallel processing algorithm. The experimental results show that the speed o f authentication is nearly doubled after optimization compared to traditional method.
