摘要: 分析一种基于二次剩余的认证协议并对其进行改进,提出基于二次剩余的增强型无线射频识别(RFID)安全认证协议。改进协议中的阅读器和标签都产生随机数,并利用Hash函数和二次剩余理论对传输的数据进行加密,从而增强系统的安全性。分析结果表明,该协议可满足RFID系统对安全和隐私的要求,且计算量和存储量较少。

Abstract: This paper analyzes the scheme proposed by Chen et al and presents an improved protocol based on quadratic residue and Hash function. In the improved protocol, random numbers are generated both by reader and tags. The transmitted information is encrypted by quadratic residue and Hash function. Analysis result demonstrates that the improved protocol not only can resist various attacks and ensure privacy, but also needs less computation and storage in the tags and server compared to other improved scheme.

Key words: Radio Frequency Identification(RFID), authentication protocol, Hash function, quadratic residue, impersonation attack, Denial of Service(DoS) attack
