Active radio frequency identification (RFID)-based power door lock control system

Abstract

The invention discloses an active radio frequency identification (RFID)-based power door lock control system, relates to a power door lock control system and an RFID technology, and in particular relates to an RFID technology-based power door lock control system. The system comprises an active RFID key card and an RFID reader, wherein the key card comprises a first singlechip, a first radio frequency chip and a first working power supply; the reader comprises a second singlechip, a second radio frequency chip and a second working power supply. A mutual authentication process between the key card and the reader is a four-way authentication process. A door lock can be automatically sensed and opened in a distance of 1.0m-1.5m away from a door by the key card based on the technologies of active RFID, stream ciphers, security authentication and the like; the key card and the reader can be in several-for-one or one-to-many corresponding relationship. The power door lock control system has the characteristics of convenience in use and high safety performance and is particularly suitable for a family security door.

Description

technical field [0001] The invention relates to an electric door lock control system and a radio frequency identification (RFID) technology, in particular to an electric door lock control system based on the radio frequency identification technology. Background technique [0002] At present, the electric door lock widely used in hotels and office buildings is an electronically controlled door lock based on passive radio frequency identification technology, including a key card and a lock body. The key fob is primarily a passive RFID tag, and the lock body is controlled by a control system that includes an RFID reader. This passive radio frequency identification electric door lock generally has a recognition distance within 10cm, and the lock can only be unlocked when the key card is in close contact with the radio frequency reader. It is quite inconvenient to open the lock when the key holder's hands are not free. At the same time, in order to control the unlocking authori...

AI Technical Summary

Problems solved by technology

The main disadvantages are as follows: 1. Proximity sensing, you need to swipe the card to open the door. It will be inconvenient for the cardholder to unlock when his hands are not empty; 2. The key card uses a passive radio frequency chip, which has no computing power and cannot operate with a higher level of security. The authentication algorithm cannot withstand replay attacks, and the authentication process is easy to be copied, replayed, tracked, blocked and tampered with; 3. The key card adopts a single protection mechanism. If it is broken, the lock body is no longer safe; 4. The key Card information is easy to be copied; 5. The shape of the key card is too single and lacks individuality
