摘要:

针对现有无线射频识别群组标签所有权转移协议中出现的后向隐私泄露、暴力破解等安全问题,提出一种改进的所有权转移协议。通过字合成、循环移位简单位运算加密随机数,以抵抗攻击者的暴力破解攻击。利用可信第三方的参与,在不经过原所有者的条件下直接向新所有者和标签下发初始密钥,进而同步更新密钥,保证协议的后向隐私安全性。使用标签所有权归属标识位定义群组标签归属权,防止出现双重所有权,同时给出协议的GNY逻辑证明。分析结果表明,该协议具有安全、低成本特性。

Abstract:

Aiming at the security issues such as backward privacy leakage and violent cracking in the existing Radio Frequency Identification(RFID) group label ownership transfer protocol,an improved ownership transfer protocol is proposed.The word randomization and cyclic shift simple bit operation are used to encrypt the random number to resist the attacker’s brute force attack.With the participation of Trusted Third Parties(TTP),the initial key is issued directly to the new owner and the label without the original owner,and then the new owner and the label synchronize the update key to ensure the backward privacy security of the agreement.The tag ownership attribution bit defines the group tag ownership,preventing double ownership and giving the GNY logic proof of the agreement.Analysis results show that this protocol is secure and low cost.
