Abstract

The invention provides a method for realizing database login authentication based on the Kerberos mechanism, including two stages of preparation for authentication and dynamic authentication. to the server; the server parses the user name information to determine whether it is the Kerberos authentication method, and if so, marks it and sends the relevant authentication data to the client; the client receives the authentication data for client identity verification; after the verification is passed, the client The terminal sends the authentication subject information of the server to the KDC, and the KDC authenticates the legal identity information of both the client and the server; the client obtains the authorization ticket certificate cred through the ticket authorization service and sends it to the server; the server decrypts the cred to obtain the client information , compared with the client authentication ID, if they are the same, the login is successful. Kerberos authentication eliminates the possibility of login password leakage, and ensures the legitimacy of the data requester and the data provider.

Description

technical field [0001] The invention belongs to the field of database login and access, and in particular relates to a method for realizing database login authentication based on a Kerberos mechanism. Background technique [0002] Database user login is an important guarantee for user security. How to make this process more secure and effective is a problem that database developers need to consider. Although Kerberos is a relatively mature authentication method, there is no application scenario for how to effectively combine it with database users. It is of great significance to realize the effective combination of GBase8a MPP database user login and Kerberos mechanism, strengthen the user security of GBase8a MPP products and improve the performance of user authentication. Contents of the invention [0003] In view of this, the present invention aims to propose a method for implementing database login authentication based on the Kerberos mechanism, so as to solve the prob...
