摘要
针对已有RFID网络所有权转移协议的计算、存储成本较高的问题,提出一种低成本的多标签、多所有者安全转移算法。首先,第三受信任方生成一个伪随机数并将标签的秘密信息传递至新所有者,所有者对收到的信息进行验证;然后,第三受信任方将秘密信息发送至各标签,标签对秘密信息进行验证。本方法仅采用一个XOR运算与128位的伪随机数生成操作,可满足被动标签的计算负载,并且具有较好的隐私性与安全性。仿真结果表明,本算法具有较低的端到端延时。
Concerned at the problem that the existing ownership transferring protocol has high computational and storage cost, a low cost ownership transferring protocol of multi-tags and multi-owners is proposed. Firstly, a pseudo-random number is generated by the third trusted party and the secret is delivered to new owner, the secret is verified by new owner; then, the secret is deliv- ered to all tags, the secret is verified by each tag. Only one XOR operation and 128 bit-wise pseudo-random number generation operations are used in the proposed method and the computational load of passive tag is satisfied, and the proposed method shows good privacy and security performance. Simulation results show that the proposed method performs lower end-to-end delay.
