Abstract
A method for providing a secure single sign-on to a computer system is disclosed. Pre-boot passwords are initially stored in a secure storage area of a smart card. The operating system password, which has been encrypted to a blob, is stored in a non-secure area of the smart card. After the smart card has been inserted in a computer system, a user is prompted for a Personal Identification Number (PIN) of the smart card. In response to a correct smart card PIN entry, the blob stored in the non-secure storage area of the smart card is decrypted to provide the operating system password, and the operating system password along with the pre-boot passwords stored in the secure storage area of the smart card are then utilized to log on to the computer system.
