RFID不确定数据的隐匿方法

The Anonymous Method of RFID Uncertain Data

RFID不确定性数据可通过查询概率值等方式获取或优化,进而达到识别不确定性数据的目的。然而,通过使用RFID不确定性处理方法,管理人员或者查询者很容易得到不确定性数据的真实情况,不确定性数据被识别以后,原有的针对RFID数据所使用的RFID安全协议将不再起作用,攻击者可以很轻松地获取当前标签的隐私数据。针对这一问题,从数据位置、隐匿范围、数据路径等三个方面提出RFID不确定数据的隐匿方法,以此保护潜在的隐私数据。

The uncertain data of RFID can be obtained or optimized by the probability of query, and then to achieve the purpose of identifying uncertain data. However, through this type of method to process the RFID data, the manage- ment of query users can get the actual circumstances of the uncertain data easily; after the uncertain data are identified, the security protocol used originally in protecting RFID data will be invalid, and the adversary can get the private data of current RFID labels easily. In order to solve this problem, this article puts forward the hiding methods of RFID uncer- tain data from the data location, hiding scope, data path to protect the potential private data.
