Data security system with encryption
A data security system is provided that includes: verifying the user by providing user identification to retrieve an authentication key; employing the authentication key for retrieving an encryption key; and employing the encryption key for allowing unencrypted communication through a storage subsystem between a host computer system and a storage media.
1. A data security method comprising:
verifying a user identification against an authentication key, the user identification supplied from outside a data security system to an electro-mechanical input mechanism or a radio frequency receiver within an electronic authentication subsystem of a portable memory device having flash memory;
employing the authentication key for retrieving an encryption key, the authentication key only accessible from inside the electronic authentication subsystem; and
employing the encryption key for allowing unencrypted communication through the storage subsystem between a host computer system and a storage media of the portable memory device having flash memory, the encryption key received from the electronic authentication subsystem by an encryption engine of the storage subsystem for decrypting the storage subsystem.
2. The data security method as claimed in claim 1 wherein employing the authentication key retrieves the authentication key as the encryption key.
3. The data security method as claimed in claim 1 wherein verifying the user includes employing a radio frequency transmitter and the radio frequency receiver for providing the user identification.
4. The data security method as claimed in claim 1 wherein verifying the user includes employing the electro-mechanical input mechanism for receiving an alphanumeric code as the user identification.
5. The data security method as claimed in claim 1 wherein the verifying the user includes employing the host computer system to provide host identifier as the user identification.
6. The data security method as claimed in claim 1 further comprising connecting the host computer system to the electronic authentication subsystem.
7. The data security method as claimed in claim 6 wherein employing the electronic authentication subsystem includes employing an authentication controller having the host computer system provide host identifier as the user identification for employing the authentication key as the encryption key.
8. The data security method as claimed in claim 6 further comprising employing a radio frequency transmitter for sending user identification to the electronic authentication subsystem having the radio frequency receiver for receiving the user identification.
9. The data security method as claimed in claim 6 wherein employing the authentication key includes employing an authentication controller for hiding the authentication key.
10. The data security method as claimed in claim 6 wherein employing the encryption key includes employing the storage subsystem for storing the encryption key.
11. A data security system comprising:
an electronic authentication subsystem for verifying a user identification against an authentication key and for employing the authentication key for retrieving an encryption key, the authentication key only accessible from inside the electronic authentication subsystem, and the user identification supplied from outside the data security system to an electro-mechanical input mechanism or a radio frequency receiver within the electronic authentication subsystem of a portable memory device having flash memory; and
a storage subsystem, including a storage media of the portable memory device having flash memory, employing the encryption key for allowing unencrypted communication through a storage subsystem between a host computer system and the storage media, the encryption key received from the electronic authentication subsystem by an encryption engine of the storage subsystem, and the encryption key for decrypting the storage subsystem.
12. The data security system as claimed in claim 11 wherein the electronic authentication subsystem includes an authentication controller for employing the authentication key as the encryption key.
13. The data security system as claimed in claim 11 wherein the electronic authentication subsystem includes the radio frequency receiver for receiving the user identification.
14. The data security system as claimed in claim 11 wherein the electronic authentication subsystem includes the electro-mechanical input mechanism for receiving an alphanumeric code as the user identification.
15. The data security system as claimed in claim 11 wherein the electronic authentication subsystem includes an authentication controller.
16. The data security system as claimed in claim 11 further comprising a host computer system.
17. The data security system as claimed in claim 16 wherein the electronic authentication subsystem includes an authentication controller for employing the host computer system to provide host identifier as the user identification for employing the authentication key as the encryption key.
18. The data security system as claimed in claim 16 further comprising a radio frequency transmitter for the sending user identification to the electronic authentication subsystem having the radio frequency receiver for receiving the user identification.
19. The data security system as claimed in claim 16 wherein the electronic authentication subsystem includes an authentication controller for hiding the authentication key.
20. The data security system as claimed in claim 16 wherein the storage subsystem contains the encryption key for allowing communication through the storage subsystem to the storage media.
