Abstract

The invention discloses a physical no-cloning technology based RFID card type intelligent door lock. The physical no-cloning technology based RFID card type intelligent door lock comprises RFID cards,a door lock and a database, wherein the database is arranged on a background server; while ID which corresponds to the RFID cards is received, data is compared with data in the database through an internet; the database is used for storing ID which corresponds to each RFID card; a door lock inner chip comprises a PUF circuit; the RFID chip comprises an RFID module which is used for generating motivation; after receiving the motivation, the PUF circuit generates a corresponding secret key; and the database provides a matching source and is compared with the secret key generated by the PUF circuit, so that authentication is realized, and therefore, unlocking is performed based on a door lock password authentication mode. The PUF circuit can resist probe attack and physical attack, and is not stored with the secret key information, so that other people cannot read a chip secret key through a probe and the like to steal inner information, and therefore, safety of the door lock is greatlyimproved.

Description

technical field [0001] The invention relates to an RFID card type intelligent door lock based on a physical non-clonable technology, belonging to the field of intelligent door locks. Background technique [0002] At present, RFID cards are widely used in identity authentication, anti-counterfeiting and other fields, but the security of RFID is not high. The current smart door locks, especially card-type smart door locks, have certain security risks, especially for reading The communication process between the device and the tag lacks effective security protection measures, and cases of RFID being captured and copied are not uncommon. Because it is in an exposed environment for a long time, it is impossible to use complex anti-attack design to protect its internal password information. At the same time, too many security modules will lead to increased power consumption and shortened service life. In the prior art, RFID technology is often used in door locks, but its security...
