Abstract

The invention discloses a user login method, a user terminal and a server. The user terminal is connected with the server. The method comprises the following steps: acquiring a user account and a user password of a user based on an input operation of the user; generating a user terminal random number, encrypting the user terminal random number, and acquiring an encrypted user terminal random number; acquiring a server random number of the server; encrypting the user password based on the user terminal random number and the server random number, and acquiring an encrypted user password; and transmitting the encrypted user password and the encrypted user terminal random number to the server, so that the user finishes login after successful verification of the user password based on the encrypted user password and the encrypted user terminal random number by the server.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a user login method, a user terminal and a server. Background technique [0002] In various websites or applications, users usually log in by way of user name and password after registration. Especially for some applications in the financial field, user login information such as account numbers and passwords will be used to log in to bank websites, etc., so as to obtain personal information such as the user's bank flow data. Obviously, during user identity authentication, a very high user login security control method is required to verify user login information to ensure that the user login password is not leaked. [0003] In the prior art, in view of the above problems, the following methods are currently used to realize user login security control: (1) adopt simple static encryption to encrypt user passwords; (2) adopt login authentication based on user terminal random nu...
