Abstract: To solve the user privacy security problems of Radio Frequency Identification(RFID), a new mutual authentication security protocol of RFID based on NTRU cryptography is proposed, and the security is based on the difficulty of finding a very short vector in a lattice of very high dimension. This protocol is superior in security, computational complexity and efficiency compared with those based on RSA and symmetric cryptography. The protocol proposed uses NTRU public key cryptography with Hash function embedded. By comparing the original Hash value with the Hash value decrypted, the data exchanged between RFID tag and reader can be protected. Research and analysis show that this protocol can effectively defeat content and location privacy attack, as well as relay attack, and is an effective way to protect RFID systems.
