Electronic lock and key and workflow control

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...

Problems solved by technology

[0004] In view of this, the object of the present invention provides the electronic key and the electronic lock device of variable encryption algorithm, variable bit anti-communication, variable password length and multiple encryption technology, multiple authentication technology, random Sequence encryption solves the problem that the above encryption algorithm is easy to be tested, cracked, and even the lock is easy to crack
