Method for generating electronic lock activation information and related system, device and unlocking method

Abstract

The invention discloses a method for generating electronic lock activation information and a related system, a device and an unlocking method. The method for generating the electronic lock activation information comprises the following steps: according to a system root key according to system root key components of at least two different bodies; dispersing lock root keys according to the system root key and electronic lock serial numbers of electronic locks by a dispersion algorithm; and generating the electronic lock activation information according to the lock root keys and time information. The method disclosed by the technical scheme of the invention has the following advantages: the system root key and the electronic lock serial numbers and other factors are dispersed to generate the lock root keys, so as to solve the problem that all existing electronic locks have the same root key; the activation information is transmitted by the Internet and is written in the lock root keys to solve the geographical coverage problem and reduce the deployment cost of a writing device and the personnel training cost; and the electronic lock activation information comprises a time factor, and an unlocking password cannot be correctly calculated if only obtaining the lock root keys but obtaining no time, so that the security is improved.

Description

technical field [0001] The present invention relates to the field of security technology, and more specifically, to a method for generating activation information of an electronic lock, a related system, equipment and an unlocking method. Background technique [0002] The dynamic electronic combination lock is a new type of lock that uses cryptography and information technology for key distribution, password calculation, and password verification. It can effectively replace the traditional mechanical combination locks of the current cash self-service equipment (ATM). The electronic combination lock system is a complete set of ATM password management and operation and maintenance tools that control and supervise the switch process of the combination lock of the safe under the ATM. [0003] The password of the dynamic electronic combination lock has the characteristics of changing with time, being invalid after expiration, and valid once. The chip in the lock has the function...

AI Technical Summary

Problems solved by technology

Both lack an unlock password that cannot be calculated correctly

However, some electronic locks have been written into the lock root key by the lock manufacturer before leaving the factory. The manufacturer has both the lock root key and the unlocking password calculation algorithm, and there is a risk that the manufacturer will unlock the lock.

The potential greater risk is that the lock root keys written by the manufacturer may have the same problem, resulting in the consequences of all locks being compromised after one electronic lock is compromised
