Abstract

The embodiment of the present invention discloses an authentication method, device and storage medium. The method includes the terminal sending the first authentication request message carrying the token to the server; the server sending the first authentication response message to the terminal; Text, the second authentication request message of the target dynamic password is sent to the server, the target dynamic password is encrypted from the local registration parameters, original key and sequence data of the terminal, and the sequence ciphertext is encrypted from the sequence data; the server will carry the second authentication result of the authentication result The response message is sent to the terminal, and the authentication result is used to indicate that the target dynamic password is authenticated according to the serial ciphertext, the server's local original key and registration parameters. Symmetric key function and HMAC technology can be used for registration and authentication between the server and the terminal, which can increase the calculation speed and reduce the time and space overhead. The sequence data has low requirements for time synchronization, and is suitable for cross-border and cross-regional terminals and Authentication of the server.

Description

An authentication method, device and storage medium technical field [0001] Embodiments of the present invention relate to security technologies, and in particular, to an authentication method, device, and storage medium. Background technique [0002] When users perform business operations such as login, payment, and transfer at the terminal, they often face theft of passwords and login credentials. Threats of listening attacks and replay attacks, the server often authenticates the user's identity to protect the user's data and property. safety. [0003] In the traditional account and password mode, the password is fixed and needs to be remembered by the user, which is generally referred to as a static password. In order to prevent illegal personnel from stealing the identity of an existing user, the dynamic password (OTP, One Time Password) is often used to log in. User identity authentication, dynamic password is also known as one-time password, the password or passwo...
