【摘要】：射频识别技术是取代传统的条形码的一种自动识别技术,通过无线射频获取用来标识实体的标签数据,从而实现实体信息的自动采集功能,具有识别速度快、标签数据存储能力强、标签可多次使用以及环境适应能力强等特点,逐渐在供应链、资产管理、产品溯源等领域得到越来越广泛的运用,提高工作效率的同时减少了相关成本。在基于射频识别技术的应用系统中,本文将RFID数据模型、读写器与应答器之间的身份合法性认证作为主要研究内容,根据RFID数据特点,对数据进行了模型化,并对读写器与标签之间的认证作了深入的研究。与普通数据相比,RFID数据具有时态性或者面向历史性、隐含语义性、批量性等特点给RFID数据的存储、管理等带了挑战。为了解决这些问题,针对RFID数据的特点,改进了一种适合在关系数据库中存储的数据模型,并且在关系数据库中实现了这种数据模型;在RFID数据的基础上,引出了RFID事件的相关概念,并且对基于规则的事件处理做出了相关介绍。在现有的批量认证基础上,针对现有方案存在的安全性和效率不高的问题,提出了一种新的批量认证方案机制,该方案在满足安全和隐私性的前提下,充分考虑了低成本电子标签的计算能力有限、存储空间不足和通信范围受限制等特性。在该认证机制中,标签被分成若干个组,同一组中的标签共用一个GroupKey。在本文提出的认证机制中,充分使用了GroupKey与每个电子标签的私有密钥之间的相互关系。同时,该方案利用了聚合哈希函数来减少阅读器与服务器之间的通信代价,取得了良好的效果。
[Abstract]:Radio frequency identification (RFID) technology is an automatic identification technology that replaces the traditional bar code. The tag data used to identify entities can be obtained by radio frequency, which can realize the function of automatic collection of entity information. Label data storage ability, label can be used many times, and the ability to adapt to the environment, and so on, gradually in the supply chain, asset management, product traceability and other fields have been more and more widely used, improving work efficiency while reducing related costs. In the application system based on RFID technology, the RFID data model, the authentication of identity legitimacy between reader and transponder are taken as the main research contents. According to the characteristics of RFID data, the data is modeled. The authentication between the reader and the tag is studied deeply. Compared with ordinary data, RFID data has the characteristics of temporal or historical, implicit semantic, batch and so on, which brings challenges to the storage and management of RFID data. In order to solve these problems, according to the characteristics of RFID data, this paper improves a data model suitable for storing in relational database, and implements this data model in relational database. The concept of RFID event is introduced, and the rule-based event processing is introduced. Based on the existing batch authentication, a new batch authentication scheme is proposed to solve the problems of low security and low efficiency of the existing scheme, which satisfies the security and privacy. The characteristics of low cost tag are considered, such as limited computing power, insufficient storage space and limited communication range. In this authentication mechanism, tags are divided into groups, and tags in the same group share a GroupKey. The authentication mechanism proposed in this paper makes full use of the relationship between GroupKey and the private key of each tag. At the same time, the aggregate hash function is used to reduce the communication cost between the reader and the server, and good results are obtained.
