Low Cost RFID Security Protocol Based on Rabin Symmetric Encryption Algorithm

Research shows that heavy-weighted RFID authentication protocol is weak to adapt to low-cost RFID tags because of the usage of public key Encryption Algorithm. The lightweight authentication protocol is suitable for low-cost RFID security authentication protocol because it adopts only the operation of AND, OR, XOR and shift, etc., but is hard to resist complex attacks. In this article, we use the features of the Rabin public key cryptography algorithm, which verifies that the signature process requires only low-cost square multiplication and modulo operations. Based on this, an RFID security authentication protocol with Rabin encryption algorithm is designed. The protocol improves the security of low-cost RFID tags to the height of the public key cryptosystem, and greatly increasing the security of low-cost RFID.
