Method for off-line generation of dynamic password and debarkation authentication and synchronization of server

Abstract

The invention discloses a method for off-line generation of a dynamic password and debarkation authentication and synchronization of a server, which is realized by the following steps: initialized information of the dynamic password is subject to application, acquisition, reset, cancel and other operations by a password management platform; the password management platform is connected with the server; a password generator saves an initial random number parameter key and a sequence number parameter index which are randomly generated and encrypted by the server; every time the password generator is used, two parameters are utilized to generate a new dynamic password; and when a user end uses an account, the account number or the user name and the dynamic password are input, computed, and authorized whether to pass and synchronously carry out the feedback of continuous debarkation or error with the same random number parameter key and the sequence number index which are saved in the server end, wherein off-line software of the password generator is arranged on equipment of a security environment with software running, storage and computation capabilities, binds a mobile equipment number for each account number name which is received and authorized by a short message gateway module, sends a short message to the bond mobile equipment number, provides binding data and generates andsends the dynamic password.

Description

technical field [0001] The present invention relates to a method for login authentication between a dynamic password and a server, in particular to generating an initial password and a serial number through the server in advance, and then generating a dynamic password and logging in with the server through the client software according to the password and the continuously incremental serial number Authentication, specifically the means to keep the server and client serial numbers in sync. Background technique [0002] A dynamic password is a password that changes according to various technical methods, and there are currently many ways to implement it. A dynamic password can be changed before or during use, and usually becomes invalid automatically after use. Therefore, the user must obtain the latest dynamic password to log in effectively. [0003] With the popularity of online games, online banking, and other online applications and web pages, users pay more and more att...

Problems solved by technology

Because it involves the problem that the mobile phone must be connected to the Internet, except that it cannot be used in an environment without a network, like other network software, it will bring other problems such as traffic, cost, loss, and mobile phone Trojan virus; or directly combine with the device identification number If you install the password generator software on your mobile phone, you can’t continue to use it if you want to change the mobile phone; there is another method, which is to calculate the algorithm through the method of time, but it may not be able to achieve synchronization well.
