Description
Technical Field
The invention relates to the technical field of identity authentication, in particular to an industrial control equipment identity authentication method and device based on a dynamic password.
Background
A dynamic Password, also called a One Time Password (OTP), is a Password that can be used only once on a computer system or other digital device, and has a validity period of only One login session or transaction.
The identity authentication based on the dynamic password is a strong authentication technology which is realized by using a cryptographic technology and is realized between a client and a server through a shared secret, and is a technical means for enhancing the static password authentication. Generally comprises a dynamic token (a miniature hardware device with a battery and a liquid crystal screen) as a password generator and an identity authentication system for managing the token and completing identity authentication.
The existing identity authentication process based on dynamic passwords is as follows:
step 0: the authentication server generates a seed Key, which is also called a Pre-Shared Key (PSK). The key is then exported to the dynamic token in an off-line manner. This step occurs only 1 time at token initialization;
step 1: when a terminal user logs in, reading a dynamic password displayed on the dynamic token through naked eyes and inputting the dynamic password on a terminal service system to be logged in;
step 2: the terminal service system submits a user name and a dynamic password to an authentication server;
and step 3: the authentication server matches the seed key according to the user name, verifies the correctness of the dynamic password value, and then returns the login result to the terminal service system.
The traditional dynamic password has the defects that the human is difficult to remember, the user needs to be informed through a specific channel, the dynamic password is read by the user and then is manually input on a system to be logged in. For example, the login is manually completed by the user through dynamic token hardware preset with a seed key or through short message notification to the user. Dynamic password-based authentication is generally used for authentication in manual intervention processes, and is difficult to use for highly automated equipment.
