DYNAMIC ENCRYPTION AND DECRYPTION METHOD IMPLEMENTED BETWEEN MODULES OF LOCK CONTROL SYSTEM, MULTIPLE-AUTHENTICATION LOCK CONTROL SYSTEM, LOCK CONTROL METHOD, AND SAFE

WIPO Patent Application WO/2021/114412

A1

Disclosed are a dynamic encryption and decryption method implemented between modules of a lock control system, a multiple-authentication lock control system, a lock control method, and a safe. The dynamic encryption and decryption method comprises: step 1, filling in hardware ID data, an unlocking communication protocol, and a mask variable according to pre-defined variable spaces, forming an array, and encrypting the array on the basis of the mask variable so as to obtain an encrypted array; and step 2, decrypting the encrypted array on the basis of the mask variable so as to obtain a decrypted array, performing data partitioning on the decrypted array according to the pre-defined variable spaces, performing matching, one by one, for pieces of data obtained from the partitioning against pre-recorded data, and if the matching is successful, performing, according to an unlocking communication protocol obtained by the decryption, a related operation, and if not, refraining from performing any operation.
