Embodiment Construction

[0181] The processor, watchdog, clock module, power management module, and indication module (small lamp, buzzer or display screen) that should be included in the computer embedded application should be included in the present invention and will not be described in detail. The random method can use a physical true random number generator, or a random number function with an encrypted seed. The following emphatically describes the first and second devices.

[0182] Implementation of the first device two:

[0183] The electronic lock includes: an automatic algorithm generation module, a password generation module, a bit reverse module, a communication module, a decryption module, a verification module, and an identification module.

[0184] in:

[0185] Automatic algorithm generation module: used to clear all stored algorithm files, bit reverse files, unlock and lock marks, identity marks and associated variables after receiving the generation algorithm instruction; generate a...

Abstract

The invention relates to the technology of electronic locks and keys and realizes industrial process control by utilizing a computer program. In order to make cipher length have variable characteristic and prevent the cipher from being cracked in the transmission process, the electronic lock and key of the invention adopt a variable encryption algorithm technology, a variable bit reversal communication technology and a multiple variable key superposition technology, which enables information transmitted between the key and the lock and information transmitted between equipment and equipment not to be utilized by other people and really achieve the effect of safety; moreover, the invention has the advantages that the encryption algorithm can be altered at any time thus, a door or a safe and the like can be installed once for good; in addition, an identification is distributed for the key by taking the lock as the core, which can make the repair and the replacement of the key to be more convenient.

Description

(1) Technical field [0001] The invention relates to an electronic lock, a key and a working program, and uses a computer program to realize an industrial process control. (2) Background technology [0002] The traditional password lock adopts the simple replacement and replacement of plaintext and ciphertext in the form of password table, and once the lock is produced, its encryption and decryption algorithm is fixed and has no flexibility. As long as one of the similar products is cracked, other products were breached at the same time. [0003] As far as the patent application number is 200410087146.0, the object of encryption in the seventh line of claim 1 is just a random sequence, and the ciphertext generated by the random sequence is only sent to the key, which only solves the problem that the password is easy to be stolen. The focus of the invention adopts The random number acts as a password, the password is variable, and it is difficult for outsiders to obtain the u...
