中文摘要：
随着EPC物联网的出现和应用,为公安情报信息获取提供了新的平台,有效地延伸和拓展了公安情报信息采集的时间和空间,但EPC物联网中更加复杂的信息实体对公安数据的管理及安全性提出了极高的要求。文章针对这种现状,在综合分析了大量安全协议的基础上,提出了一个适用于低成本标签的并且满足可扩展性的安全认证协议,即一个基于假名的可扩展的RFID安全认证协议,通过利用后端数据库的存储空间降低后端数据库搜索标签的次数和计算次数,不仅保护用户数据隐私,而且优化后端数据库标签假名的更新,实现了可扩展性。
英文摘要：
With the appearance and application of the EPC Internet of things, for the public security information acquisition provides a new platform, effectively and extend the public security information acquisition time and space, but EPC Internet of things in more complex information entity of public security data management and security challenges. This article in view of this situation, in a comprehensive analysis of a large number of security protocol based on, puts forward a suitable for low cost tag and satisfy extensible authentication protocol, namely the one based on the pseudonym of scalable RFID security authentication protocol, through the use of a back-end database storage space and reduce the number of back-end database search tags and calculation of frequency, not only to protect the privacy of user data, and optimization of the back-end database label pseudonym update, achieving scalability.
