Since the current RFID systems have potential security problems in privacy, an improved method based on the random Hash lock is proposed following the analysis of several typical RFID methods. It can effectively prevent location tracking, eavesdropping, replaying and so on. In addition, it has many other advantages, such as s low computation complexity, low label cost and high security.
In order to solve the contradiction between information sharing and security privacy in the ubiquitous computing environment, a novel context policy management framework based on ontology is presented. The semantic specification of policy and dynamic policy implementation are described. And the usefulness and flexibility of our proposed framework are demonstrated by a typical ubiquitous computing...
The RFID technology is recently predicted to spread in most of our daily lives. However, it is very much vulnerable as it faces some major security challenges and threats. Thus, RFID technology also provides the solutions for the security threats concerned with security, privacy, and authentication. This paper not only addresses security privacy and authentication but also proposes a lightweight mutual...
