Embodiment

[0044] Assuming that an illegal attacker conducts 5 illegal attacks on the tag, the access counter of the tag at this time is not synchronized with the initial secret value and the counter value and secret value stored in the background database. Set the initial counter value to 0 and the initial secret value to S t Then the data stored in the tag at this time is: encrypted value H 5 (S t ), the flag bit T is 1, and the access count value k t is 5, and the ID value IDS encrypted with the public key. The background database stores a set of values ​​indexed by ID (ID, 0, S d ), where S d with S t equal.

[0045] Specifically follow the steps below:

[0046] Step (1): The RFID reader initiates an authentication request, and at the same time requests the initial seed S r Perform a hash operation to get the hash value w, send w to the label and update the seed value S r =w;

[0047] Step (2): The RFID tag responds after receiving the reader's authentication request, and pe...

Abstract

The invention discloses an RFID safety certificate protocol based on a Hash function and an elliptical curve. According to the protocol, the Hash function based on a Sponge structure is used to ensurefreshness of the protocol and identity authentication, a pre-encrypted ID value is used to replace an original ID value, a background database uses a decrypted ID value as an index value, an access counter value is used for synchronization, a flag bit is used to determine whether desynchronized attack occurs, and repeated calculation is avoided. The RFID safety certificate protocol based on the Hash function and the elliptical curve can be used to solve the problem in security of a forward channel and the problem of low efficiency of label retrieval and authentication.

Description

technical field [0001] The invention belongs to the technical field of RFID system security authentication, and relates to an RFID security authentication protocol based on a hash function and an elliptic curve. Background technique [0002] In order to ensure the security of the wireless channel in the RFID system and avoid the privacy leakage of the electronic tag, it is necessary to use a security protocol to complete the authentication of the tag during the communication process. In view of the limited resources of the RFID system, most of the security authentication protocols used in it are security protocols based on the Hash function (hash function). At present, a large number of authentication protocols based on the Hash function have been proposed, including scholars Sarma and others published "Radio- Frequency Identification: Security Risks and Challenges", the Hash-Lock protocol proposed in the paper, "Security and Privacy Aspects of Low-Cost Radio Frequency Ident...
