A Novel Authenticated Encryption Algorithm for RFID Systems

In this paper a light symmetric encryption algorithm is presented for resource constrained applications like RFID systems. In this algorithm some extra bits are distributed among plaintext bits where the location of these bits inside the cipher text is the secret key. The algorithm provides confidentiality, authentication, and integrity services. Experimental results confirm that its area overhead and power overhead is less than other known symmetric algorithms proposed for RFID systems.
