RFID lightweight mutual authentication using shrinking generator

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 authentication suitable to be implemented for passive RFID tag. The proposed protocol is simple, low cost and low power consumption as well as efficient computation since it uses the simple and low cost Shrinking Generator that can be considered an alternative for the use of the One Time Pad algorithm.
