中文摘要：

为解决标签与读写器之间的共享密钥因事先设置好而存在的安全缺陷问题,提出一种共享密钥无线生成算法。采用无线生成密钥的方式,将读写器产生的随机数通过字合成运算函数进行加密,通过动态的方法生成标签与读写器之间的共享密钥值,使得共享密钥值不需要事先进行设置。全面的安全性分析结果表明,该算法可以解决安全缺陷,在计算量及实现所需的门电路方面优于现有算法。

英文摘要：

To solve the existing security problem caused by the pre-set shared private key between the tag and the reader,a wireless generation algorithm for the shared private key was proposed.The wireless key generation was adopted,random number generated using the reader was encrypted using word synthesis arithmetic function.Through the dynamic generation method,shared key value between tag and reader was produced,hence the key value did not need to be set in advance to share.Results of comprehensive security analysis show that the proposed algorithm can solve the security defects and it is superior to the existing algorithms in terms of computational complexity and required gate circuits.
