A dynamic password lock system and method for self-service equipment network management

Abstract

The invention discloses a dynamic password lock system and a method for self-help network management. Due to adoption of the method, opening, closure, control on opening rejection and information record of a safe case door of self-help equipment, namely, an application terminal, are achieved, and an unlocking password is transmitted to the self-help equipment to display from a servo through the conventional network of the self-help equipment, then a person can input the password on a password lock to open the safe case door lock. The dynamic password lock system consists of a lock, a lock inner circuit unit and an information input and output device. The dynamic password lock system has the advantages that in addition that fixed initialization data and variable operation data are input into an algorithm input terminal, dynamic time data are also introduced, a dynamic password is obtained for identity verification, and moreover the dynamic password is only valid within certain time, so that the security is greatly improved, the password does not need to be changed at regular time, and high practical values and practical significance are achieved.

Description

technical field [0001] The invention relates to a dynamic password lock system and method for self-service equipment network management, belonging to the technical field of information security. Background technique [0002] At present, in the field of existing self-service equipment and other door lock control areas with high security requirements, traditional mechanical locks, electronic locks and biometric locks cannot fully meet the needs of customers in certain industries. There are some defects more or less in these traditional door locks. For example, once the password is generated, it is not easy to change frequently or the cost of each replacement is high. For example, if the person who masters the password is temporarily replaced, too many people who know the password will easily lose the secret. For example, once the password is generated and given, it is difficult to manage and other defects. [0003] The password mentioned in the traditional password authentica...

AI Technical Summary

Problems solved by technology

[0004] (1) Ease of use and security of static passwords are mutually exclusive, and the two cannot be balanced. Simple and easy-to-remember passwords are weak in security, and complex static passwords are highly secure but difficult to remember and maintain;

[0005] (2) Static passwords have low security and are vulnerable to various forms of security attacks;

[0006] (3) The risk and cost of the static password is high, and once it is leaked, it may cause the greatest loss, and before the loss occurs, it is usually not known that the static password has been leaked;

[0007] (4) The use and maintenance of static passwords is inconvenient, especially when a user has several or even more than a dozen static passwords to use and maintain, the static password is forgotten and operations such as reporting the loss and resetting after forgetting usually need to spend a lot of money Time and energy will greatly affect the normal use experience

[0008] Therefore, although the static password mechanism is very simple to use and deploy, in terms of security, the static password is a single-factor identity authentication method, which can no longer meet the needs of using the Internet to manage password locks for identity authentication security.
