具有结构化密钥管理的专用RFID身份验证通过多个标签共享组密钥，以对数顺序安全地分隔RF标签。但是，如果系统中的某些标签被关联的篡改组密钥泄露，则会降低标签的隐私程度。在保持快速认证速度的同时提高标签的隐私程度，相当于降低组密钥的相关概率。为此，我们提出了基于随机跳过图的身份验证（RSGA），该方法在匿名性方面显著提高了标签的隐私性，并且密钥存储成本合理。仿真结果表明，该方案达到了设计目标。
Private RFID authentication with structured key management securely singulates RF tags in the logarithmic order by having group keys shared by several tags. However, the degree of tags’ privacy will decrease should some tags in the system be compromised by correlating tampered group keys. Improving the degree of tags’ privacy in keeping with fast authentication speed is equivalent to reducing the correlation probability of group keys. To this end, we propose Randomized Skip Graphs-Based Authentication (RSGA) that significantly improves the tags’ privacy in terms of anonymity with reasonable amount of key storage cost. The simulation results demonstrate that the proposed scheme achieves it design goals.
