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...

Examples

Embodiment Construction

[0027] Such as Figure 1 to Figure 2As shown, an encryption device and method is mainly controlled by code-hopping remote control T10, LCD keyboard programmer TK60, code-hopping receiving control host TT90, matching battery 25 of code-hopping remote control T10, connectors 26, 27, 32, and Electrical appliance M, supporting power supply etc., liquid crystal keyboard programmer TK60 connector 19 connects jumping code remote controller T10 connector 22 through connector connection line 26, jumping code remote controller T10 has erasing key circuit and jumping code programming transmitting circuit, these two The circuit shares one chip: read protection code hopping programming chip 23, such as HCS series chip HCS301, the EEPROM of HCS301 can be erased and written 100,000 times, and can be stored for 30 years. The read protection of HCS301 means that the original key must be erased before the key is written. It can only be written, and the read key can only be read when the key is ...
