Abstract

The invention provides an authentication method, an unlocking method and an unlocking system for a dynamic password lock. The authentication method comprises the following steps: setting a third algorithm corresponding to a first algorithm and a fourth algorithm according to a second algorithm in a hand-held terminal for unlocking the dynamic password lock; generating a first authentication sequence on the hand-held terminal side by use of a first key number set through the third algorithm, and generating a second authentication sequence through a second key number set received from the dynamic password lock through the fourth algorithm; generating a fourth authentication sequence on the dynamic password lock side through the second key number set of the current side through the second algorithm, and generating a third authentication sequence through a first key number set received from the dynamic password lock through the first algorithm; and carrying out corresponding steps, and determining that the authentication is passed in the case that the first and the third authentication sequences are correspondent and the second and the fourth authentication sequences are correspondent. By adopting the authentication method provided by the invention, the security performance of the dynamic password lock can be improved.

Description

technical field [0001] The present invention relates to a security technology, in particular to a method for opening a lock, in particular to a method for unlocking based on a handheld terminal device. Background technique [0002] At present, vaults, gun stores, automatic teller machines, safes, safes, confidential file cabinets, etc. are all equipment with very high security requirements, and are key security parts. The focus of such security measures is the door lock. Existing door locks are generally combination locks, and generally there is a cabinet door that can be opened as long as the combination is mastered. The disclosure of the password is easy to cause serious robbery accidents. Contents of the invention [0003] The problem to be solved by the present invention is that the security performance of the existing dynamic combination lock is poor, and the password holder is easy to leak the password, leading to illegal opening of the cabinet door, which increase...
