System and method for authentication

摘要

An authentication system ( 10 ) to verify a password is provided. The authentication system includes a first storage unit ( 16 ) to store an authentication sequence ( 24 ) and a read-only memory unit ( 18 ) on which an authentication algorithm ( 26 ) is programmed. A microcontroller ( 20 ) is coupled to the first storage unit, the read-only memory unit and a web server. The microcontroller receives the password and executes the authentication algorithm to verify the password with the authentication sequence. A second storage unit ( 22 ) is coupled to the microcontroller to store data from the web server. Access to a second storage unit is permitted by the microcontroller only if the password has been verified.
