The RFID mutual authentication scheme based on ECC and OTP authentication

In the RFID environment with limited storage and computing resources, it is necessary to adopt appropriate and effective lightweight authentication technologies to ensure the security of RFID operating environment. After studying existing RFID authentication scheme and analyzing its security, a mutual authentication scheme based on ECC and OTP authentication is proposed. In this scheme, authentication information introduces a random number and a time stamp based on the traditional OTP authentication, and ECC is used to encrypt the authentication process for the its information confidentiality. The safety analysis shows that it meets basic security requirements and resists tracking, replaying, counterfeiting and other kinds of attacks. At the same time, it achieves mutual authentication between the tags and the database sides, which improves the security of RFID environment well.
