Abstract

A method for permitting access to secured computer resources based upon a two-piece user verification process. In the disclosed embodiment, the user verification process is carried out during a secure power-up procedure. At some point during the secure power-up procedure, the computer user is required to provide an external token or smart card to the computer system. The token or smart card is used to store an authentication value(s) required to enable secured resources. The computer user is then required to enter a plain text user password. Separate passwords can be used to enable various portions of the computer system. Once entered, a one-way hash function is performed on the user password. The resulting hash value is compared to an authentication value (token value) downloaded from the token. If the two values match, the power-on sequence is completed and access to the computer system and/or secured computer resources is permitted. If the two values do not match, power to the entire computer system and/or secured computer resources are disabled. The two-piece nature of the authorization process requires the presence of both the user password and the external token in order to access protected computer resources.
