Abstract

The invention relates to a RFID ownership transfer method. For example, the RFID ownership transfer method comprises the following steps: a) downloading a digital certificate containing ECC public and private keys from a credible third party to a RFID reader-writer; b) initializing a RFID label, and introducing an ECC public key certificate of the RFID reader-writer into the RFID label to serve as an owner public key certificate, so as to assign the ownership of the RFID label to the RFID reader-writer; c) executing an anonymous authentication protocol by the RFID reader-writer and the RFID label to realize the bidirectional authentication of the RFID reader-writer and the RFID label; and d) executing an ownership transfer protocol by the RFID label, and transferring the ownership of the RFID label from the RFID reader-writer to another RFID reader-writer through a justice and arbitration mechanism provided by the credible third party. Therefore, the method is used for improving the security and the operation efficiency, and thus having a good application prospect.

Description

technical field

[0001] The invention relates to the technical field of radio frequency identification, in particular to an RFID ownership transfer method. Background technique

[0002] RFID (radio frequency identification: radio frequency identification) is a non-contact automatic identification technology, which automatically identifies the target object and obtains relevant data through radio frequency signals, and the identification work does not require manual intervention. It has the advantages of waterproof, antimagnetic, high temperature resistance, long service life, large reading distance, data on the label can be encrypted, storage data capacity is larger, and storage information is more comfortable. Its application will bring revolutionary changes to industries such as retail and logistics. .

[0003] In 1985, Neal Koblitz and Victor Miller respectively proposed Elliptic Curve Cryptography (Elliptic Curve Cryptography, ECC). ECC depends on the difficulty of solv...
