Description

RFID communication method and system
Technical Field
The invention belongs to the technical field of RFID (Radio Frequency Identification ), and particularly relates to an RFID communication method and system combining PUF (Physical Unclonable Functions, physical unclonable function) technology.
Background
RFID is a radio frequency identification technology that results from combining integrated circuits with wireless communication technology. On the working frequency, the RFID is divided into a plurality of frequency bands of 125KHz to 134KHz, 13.56MHz in high frequency, 860MHz to 960MHz in ultrahigh frequency, 2.45G of microwave and 5.8G. In the working mode, the RFID can be mainly divided into a passive RFID and an active RFID.
PUF technology is a circuit technology that generates unpredictable, uncloneable, and tamper-proof keys by extracting random differences that inevitably occur during the fabrication of integrated circuits. Unlike traditional security solutions, PUF technology can dynamically generate an infinite number of unique keys without storing keys for encryption, and thus has a great application prospect in the field of security and anti-counterfeiting.
Conventional RFID technology stores a tag ID or a key in a nonvolatile memory inside the tag, and communication between the reader and the tag is not encrypted. For application occasions such as identity recognition, security authentication and the like, key information is easily cracked and labels are forged by information interception, information copying and other methods, so that the security of the system is jeopardized.

In some embodiments, the information encrypted with a key to the tag is decrypted by the reader only using the same key. In some embodiments, the information encrypted with a key to the reader, the tag can decrypt the information only using the same key.
(5) After receiving the encrypted follow-up information sent by the reader, the tag decrypts the received information by using the extracted key to obtain the information sent by the reader and responds to the information to generate response information, and then encrypts the generated response information by using the extracted key and sends the response information back to the reader.
(6) After receiving the encrypted response information sent by the tag, the reader decrypts the received encrypted response information by using the queried key to obtain the response information of the tag.
(7) And the communication between the reader and the tag is finished, the tag closes the PUF circuit in the tag, and the extracted key is deleted.

The PUF circuit is used for generating a key after the tag receives a radio frequency carrier signal and a query command sent by the reader. The key extraction module is used for extracting a key generated by the PUF circuit. The second encryption and decryption module is used for encrypting the preset check code of the RFID system by using the key extracted by the key extraction module and sending the encrypted check code back to the reader.
The tag-key library is used to store pre-registered tag-key information obtained by registering, in a secure environment, keys generated by PUF circuits within all tags and within each tag within the RFID communication system. And the key inquiry module is used for inquiring a pre-registered tag-key library after receiving the encrypted check code sent by the tag to obtain a key corresponding to the tag. The first encryption and decryption module is used for performing decryption attempt on the encrypted check code sent by the tag by using the key inquired by the key inquiry module until the check code is successfully decrypted.
The first encryption and decryption module is also used for encrypting the information to be sent by the reader subsequently by using the key inquired by the key inquiry module after the communication connection between the reader and the tag is successfully established, and then sending the information to the tag.
The second encryption and decryption module of the tag is further used for decrypting the received information by using the key extracted by the key extraction module after receiving the encrypted follow-up information sent by the reader after the communication connection between the reader and the tag is successfully established, obtaining the information sent by the reader and responding, generating response information, encrypting the generated response information by using the key extracted by the key extraction module, and sending the response information back to the reader.

The invention replaces the method of storing the key in the nonvolatile memory by the method of extracting the key by the integrated PUF circuit, starts the PUF circuit when in use, extracts the key, closes the PUF circuit when not in use, and deletes the key. Therefore, the tag does not need to store the key, and the key extracted by the PUF circuit has unpredictable, copying and tampering characteristics, so that the security problem of the key is solved. Furthermore, the reader and the tag both use the secret key extracted by the PUF circuit, and encrypt the communication information by adopting the same encryption algorithm, and only the real secret key is obtained to decrypt the real information, thereby solving the problem of communication safety.
