Design of a Mutual Authentication Protocol for RFID Based on ECC

ABSTRACT

A low-cost, efficient and safe mutual authentication protocol for RFID based on elliptic curve cryptography (ECC) is proposed, specific to the security and privacy problem existed in the existing RFID authentication protocol, on the basis of deep analysis of the existing RFID protocol based on ECC. As to this proposal, mutual authentication between the tag and reader can be realized only through two sessions, under the condition of not destroying the security strength. So, the workload of calculation and system resource expense are reduced. The paper has described the protocol in detail and analyzed its security. The analysis result shows that, the protocol can resist tracking attack, replay attack, man-in-themiddle attack and other attacks, has good forward security and can realize mutual authentication between the server and the tag. Besides, it has definite practicability, due to low cost, security and scalability.
