Abstract

The invention discloses a password remote lock control system based on the AES cryptographic algorithm, which comprises a key unit and a lock unit. The key unit is composed of a timer A, a keyboard and a receiver A, a decoder A, a processor A, a random number generator A, an encipher A and a transmitter A connected in sequence; the lock unit is composed of a timer B and a transmitter B, an encipher B, a random number generator B, a processor B, a decoder B and a receiver B connected in sequence. By adopting the 256-bit key AES cryptographic algorithm, the password remote lock control system encrypts the time-variant random numbers and carries out the bidirectional communication transmission between the key and the lock, thereby avoiding being decoded by the prior various decoding manners, maximizing security, reliability and compatibility of the password remote lock and protecting a user's property.

Description

technical field [0001] The invention belongs to the technical field of security, and relates to a password remote control lock control system, in particular to a password remote control lock control system based on an AES encryption algorithm, and also relates to a control method of the system. Background technique [0002] Due to its safety and convenience, password remote control locks are widely used in anti-theft systems such as automobile central control locks (central control door locks), floors, doors and windows. Its working principle is that the random number generated by the key is encrypted by an encryption algorithm, and an encrypted signal is sent to the lock. After the lock receives the encrypted signal sent by the key, it is processed to verify whether it matches. If they match, the lock generates a response signal and encrypts it through an encryption algorithm, then feeds it back to the key, and at the same time, executes the corresponding action. If it doe...
