Embodiment Construction

[0014] figure 1 Shown is a block diagram of the anti-theft system of the present invention, including a lock body unit 1 and an authorized mobile device 2 corresponding thereto, and the authorized mobile device 2 and the lock body unit 1 are wirelessly connected through a mobile phone network, a WiFi network, a Bluetooth network or a Zigbee network, etc.; The body unit 1 comprises a transmitter / receiver 11 , a microprocessor 12 , a microcontroller 13 and a lock actuator 14 . The authorized mobile device 2 is carried by the user, and the lock body unit 1 is installed at the door of a private house. When the user wants to unlock remotely, such as opening the door for a child or pet without a key or an authorized mobile device, the user uses the authorized mobile device to select one or more sets of key curves received last time according to the agreed rules and Together with the door opening command, it is sent to the lock body unit. The aforementioned agreed rules, for exampl...

Abstract

The invention discloses an anti-theft system, comprising a wirelessly connected authorized mobile device and a lock body unit, the lock body unit comprising a transmitter / receiver, a microprocessor, a microcontroller and a lock actuator; wherein the microprocessor Generate one or more sets of key curves from the stored key graph according to an encryption algorithm and send them to the authorized mobile device; the authorized mobile device selects one of the key curves when sending an instruction and sends it together with the instruction To the lock body unit; when the transmitter / receiver receives the key curve and the instruction, the microprocessor generates the key graph according to the decryption algorithm and compares it with the pre-saved key graph, if decrypted If the generated key pattern is the same as the pre-saved key pattern, the microprocessor transmits the instruction to the microcontroller, and the microcontroller controls the execution of the operation corresponding to the instruction; otherwise, the microcontroller does not execute the instruction. the instruction.

Description

technical field [0001] The invention relates to an anti-theft system, in particular to an anti-theft system utilizing wireless communication and dynamic information encryption technology. Background technique [0002] M2M / D2D (Machine to Machine, or Machine Interaction) is an emerging technology application, which uses wireless signals, especially through mobile phone networks or WiFi networks, to complete the interaction between two or more machines / devices, remotely The remote control realizes the function of the machine / equipment. Low-end M2M applications, such as smart homes, use mobile phones to remotely adjust and control non-secure equipment such as air conditioners, refrigerators, and induction cookers. When M2M / D2D is applied in the anti-counterfeiting field of security equipment or luxury products, signal encryption and interaction encryption are a key issue. Affected by cost, power consumption, and computing speed of a microprocessor, many commonly used encrypti...
