Abstract

The invention discloses a temporary password entrance guard system with dynamic update of encrypting parameters, which can be applied to real-time on-line and non-real-time on-line entrance guard systems. A temporary password formed by the system is generated on the basis of algorithm, time and a random number SEED and is sent to an applicant by a password management server; and meanwhile, the password management server sends a latest random number SEED to an entrance guard controller through network or an intermediate device; the applicant tells the temporary password to a user, so that the user can input the temporary password on the entrance guard controller, and then the entrance guard controller inverse-calculates the generation time of the temporary password according to decrypting algorithm, the temporary password and the random number SEED and compares the generation time with present time; if the time difference is located in a setting range, the password is legal and the entrance guard controller performs unlocking action. The temporary password is variable with time and dynamic parameters, so that reliability and adaptability are better.

Description

technical field [0001] The invention relates to the technical field of intelligent access control, in particular to a temporary password access control system with dynamically updated encryption parameters. Background technique [0002] At present, the way of unlocking by inputting a password is the most widely and most easily operated verification and unlocking method, which can be divided into three types: [0003] The first type is a fixed password method that can be set. The password is stored in a non-volatile memory, and the password is input every time the lock is unlocked. The input password and the password in the memory are checked for consistency to unlock. Modify the password value in non-volatile memory, updating the password for enhanced security. This method has the worst security. Once the old password is leaked, before the memory password is updated, the owner of the old password can completely unlock the lock without hindrance. [0004] The second type is...
