The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A storage device for promoting security in a computer system, the storage device comprising:
a storage medium for storing data;
firmware for reading data from and writing data to the storage medium; and
a partition defined on the storage medium for dividing the storage medium into a data partition and a secure data partition, the secure data partition for storing secure data and one or more authority records, wherein the one or more authority records define access permissions relating to the secure data partition and the secure data;
wherein the secure data partition contains a master authority record, wherein the one or more authority records can be created and deleted as required by a user having access permissions according to the master authority record; and
wherein only the firmware is permitted to access the secure data and the one or more authority records.
2. The storage device of claim 1 wherein the storage device is in communication with a computer system having an operating system.
3. The storage device of claim 2, wherein secure data stored in the secure data partition is invisible to the operating system.
4. The storage device of claim 1 wherein each of the one or more authority records contains one public-private key pair for authenticating data that originates from the security partition.
5. The storage device of claim 1, wherein the storage device further comprises:
cryptographic operations embedded in the firmware of the storage device.
6. The storage device of claim 5, wherein cryptographic code is authenticated with a root assurance in the firmware of the device, wherein the firmware is non-writable.
7. A method for promoting security in a computer system having an operating system in operative connection with a storage device, wherein said storage device includes a processor and firmware for processing data stored on the storage device, the method comprising:
partitioning a storage medium of the storage device into a data partition and a secure data partition, the data partition being accessible to a user and the secure data partition being invisible to the user, the secure data partition for storing secure data and one or more authority records, wherein the secure data is encrypted and a cryptographic code is embedded in the firmware;
restricting access to the secure data partition such that only the firmware may access the secure data and the one or more authority records; and
authenticating the cryptographic code with a root assurance in the storage device.
8. The method of claim 7, further comprising:
prohibiting access to the secure data partition by the operating system of the computer system.
9. The method of claim 8, wherein a portion of the firmware is non-writable.
10. The method of claim 7, further comprising:
writing data to the secure data partition by executing of a portion of the firmware of the storage device; and
associating the data with a particular record of the one or more authority records.
11. The storage device of claim 1, wherein the secure data is accessed by the firmware using a security partition open call internal to the storage device and hidden from a user.
12. A storage device comprising: a storage medium having a security partition containing one or more authority records and at least one data set associated with each of the one or more authority records; and
a mechanism within the storage device adapted to limit access to the security partition based on the one or more authority records, wherein the mechanism comprises a processor disposed within the storage device adapted to limit access to the security partition by an operating system of a computer system, and firmware disposed within the storage device adapted to limit access to the security partition by an operating system of a computer system.
13. The storage device of claim 12 wherein the one or more authority records comprises a master authority record including instructions for governing the one or more authority records in said storage device.
