A scheme to enhance security of RFID middleware

Radio Frequency Identification (RFID) systems have become popular for automated identification and supply chain applications, This article focuses on the problem of privacy and security, propose a security scheme to deter unauthorized users from accessing the tag and other problems that could lead to the violations of information stored in the tag, ensuring the safety transmission of data. Then the paper presents the security implementation based on the architecture of the scheme. Finally make an evaluation to the scheme both in the security and in the efficiency.
