    摘要: There is provided a method of providing secure access to data stored in a system memory of a computer system, the computer system comprising a memory controller for writing data to and reading data from the system memory. The method comprises generating a random encryption key each time the computer system is booted and storing the random encryption key in a volatile memory region of the memory controller. The method additionally comprises encrypting data using the random encryption key to create encrypted data, and storing the encrypted data in the system memory. Also provided are a memory subsystem and a computer system for performing the method.

    摘要: A system comprises a basic-input-output-system (“BIOS”), a disk drive, and a security system configured to prevent unauthenticated access to the disk drive. For each of at least two users out of a plurality of users, the BIOS authenticates the user based on the user's token. The BIOS also accesses secured data based on the authentication, and provides the secured data to the security system without input from the user.
