Encryption device and method

Abstract

The invention relates to an encryption wireless code hopping remote control system intelligent technology. An encryption device mainly comprises a code hopping remote controller, a liquid crystal keyboard programmer, a code hopping receiving control host, a battery matched with the code hopping remote controller, multiple joint connecting wires, a control electrical appliance, a matching power supply and the like, wherein the liquid crystal keyboard programmer is respectively connected with the code hopping remote controller and the code hopping receiving control host through the joint connecting wires, the code hopping remote controller comprises an erasing and writing key circuit and an output code hopping transmitting circuit, the code hopping receiving control host comprises an erasing and writing user code key circuit and a receiving and decoding confirmation and implementation circuit, the liquid crystal keyboard programmer comprises a liquid crystal display screen for text prompt, 16 keyboard buttons and a special programming circuit for writing self-edited user codes, and the encryption device and the method can basically eliminate unsafe factors of artificial secret-leaking and lead the system to be more secure and reliable. The encryption device and the method have the advantages of small volume, light weight, simple operation, safety, reliability and convenience, and can realize the new objectives of intelligentization and security protection intelligentization of a lock during the information age.

Description

technical field [0001] The invention relates to the technical field of wireless encryption intelligence, in particular to the intelligent technology of an encrypted wireless code-hopping remote control system. Background technique [0002] In the existing door remote control unlocking and electric control cabinet remote control unlocking, especially in the car remote control unlocking, almost no user edits and writes the user code by himself. code remote control, the HCS300 chip is based on the KEELOQ algorithm and uses advanced non-linear bit encryption technology to generate highly confidential code hopping. The code sent each time is unique, irregular, and non-repetitive, making any Deciphering methods such as illegal capture and scanning tracking have come to naught, and have been successfully applied to various security products, such as remote access control systems, car remote control unlocking and other fields, but because the user code is not edited and written by t...

[0002] In the existing door remote control unlocking and electric control cabinet remote control unlocking, especially in the car remote control unlocking, almost no user edits and writes the user code by himself. code remote control, the HCS300 chip is based on the KEELOQ algorithm and uses advanced non-linear bit encryption technology to generate highly confidential code hopping. The code sent each time is unique, irregular, and non-repetitive, making any Deciphering methods such as illegal capture and scanning tracking have come to naught, and have been successfully applied to various security products, such as remote access control systems, car remote control unlocking and other fields, but because the user code is not edited and written by the user, and due to A variety of reasons lead to the loss of user codes, such as the decryption of the code-hopping receiving control host, providing opportunities for theft criminals, causing property losses and personal insecurity to users, such as car theft and other losses
