Abstract

The invention provides an identity authentication method and system and a password protection device. The identity authentication method includes the steps that the password protection device and a server synchronously update dynamic matrixes; the password protection device receives a user password inputted by a user; the password protection device utilizes the dynamic matrix to carry out conversion on the user password so as to generate a first dynamic password, and then outputs the first dynamic password; the server utilizes the dynamic matrix to carry out conversion on the user password, stored in the server, of the user so as to generate a second dynamic password; the server receives the first dynamic password, compares the first dynamic password with the second dynamic password and then confirms that the user is authenticated when the first dynamic password accords with the second dynamic password. Through the identity authentication method, the burden of the user for remembering the password is effectively relieved, and the identity authentication efficiency and security of identity information of the user are improved.

Description

technical field [0001] The invention relates to the field of digital information transmission, in particular to an identity authentication method, system and password protection device. Background technique [0002] The current Internet identity authentication generally adopts the user name / password authentication method. Users set a unique username and a password known only to themselves. When the user logs in, enter the user name and password, and send them to the server in plain text or encrypted form. The server compares the password sent by the user with the password stored in the server. If they are consistent, the user identity authentication is passed and the user is allowed to log in. Deny user login. [0003] However, in the existing static password technology, since the password input by the user is the same every time for login verification, and needs to be transmitted in the computer memory and in the network, it is easy to be intercepted by a Trojan horse pro...
