In this paper, we propose a symmetric encryption algorithm for RFID systems called RBS (Redundant Bit Security). RBS is based on inserting redundant bits into the original data bits. The location of redundant bits inside the transmitted data represents the secret key. The redundant bits are generated by Light Weight Mac algorithm in order to provide integrity and authentication as well. The implemented hardware architecture meets the resource constraints of RFID systems, and encryption and decryption time is shorter compared to existing algorithms. I.

In this paper, we present RBS (Redundant Bit Security) algorithm which is a low-complexity symmetric encryption with a 132-bit secret key. In this algorithm redundant bits are distributed among plaintext data bits to change the location of the plaintext bits in the transmitted data without changing their order. The location of redundant bits inside the transmitted data represents the secret key between sender and receiver. The algorithm provides integrity and authentication of the original data as well. The implementation comparison of this algorithm with other algorithms confirms that it a good candidate for resource-constraint devices such as RFID systems and wireless sensors.
