Message authentication (sometimes called data origin authentication) is the assurance that a given entity was the original source of the received data. Entity authentication (or user authentication) is the assurance that a given entity is involved and currently active in a communication session.
Data authentication is a critical mechanism to maintain data integrity and nonrepudiation . Data authentication may be achieved either using conventional encryption algorithms or using public-key cryptography (PKC).
The DBMS authentication feature removes the need to add an operating system user every time a new user needs to access a database . A user who is appropriately defined in the database can access the database using a valid Vector user name and password.
