Abstract

A system for recovery of data access of a locked secure storage device can comprise a keystore module and an authorization module. The keystore module may be configured to allow access to a master file system comprising a user encryption key for data stored within the locked secure storage device based on a master code. The authorization module may be configured to receive the administrator code, authenticate the administrator code, decode the master code, and reset a lockout parameter of the locked secure storage device.

Claims (43)

1. A system for recovery of data access of a locked secure Universal Serial Bus (USB) storage device, the system comprising:

a secure USB storage device, the secure USB storage device being locked so as to no longer accept any user code, the secure USB storage device comprising:

a keystore module configured to allow access to a master file system comprising a user encryption key for data stored within the locked secure USB storage device based on a master code; and

an authorization module configured to receive an administrator code, authenticate the administrator code, decode the master code, and reset a lockout parameter of the locked secure USB storage device, thereby permitting acceptance of a user code.

2. The system of claim 1 , wherein the locked secure USB storage device comprises a locked detachable secure USB storage device.

3. The system of claim 1 , wherein the locked secure USB storage device comprises the master file system.

4. The system of claim 1 , wherein the locked secure USB storage device further comprises a user file system.

5. The system of claim 1 , wherein the authorization module is further configured to receive a user code and decrypt the user encryption key using the user code.

6. The system of claim 1 , wherein authenticating the administrator code comprises the authorization module configured to detect an administrator secure USB storage device.

7. The system of claim 6 , wherein the authorization module is further configured to verify the administrator code.

8. The system of claim 1 , wherein resetting the lockout parameter comprises the authorization module configured to reset a number of consecutive user code attempts.

9. The system of claim 1 , wherein resetting the lockout parameter comprises the authorization module configured to receive a new user code from the administrator.

10. The system of claim 1 , wherein resetting the lockout parameter comprises the authorization module configured to provide a user encryption key to an administrator.

11. The system of claim 10 , wherein the user encryption key is encrypted by a user code.

12. The system of claim 10 , wherein the user encryption key is encrypted by an administrator encryption key.

13. The system of claim 1 , wherein resetting the lockout parameter comprises the authorization module configured to provide a master encryption key for the locked secure USB storage device to an administrator based on the master code.

14. The system of claim 1 , wherein the locked secure USB storage device is in a locked state due to the receipt of an incorrect user code a predetermined number of times, and the locked secure USB storage device cannot be unlocked by receipt of a correct user code.

15. A method for recovery of data access of a secure Universal Serial Bus (USB) storage device, the secure USB storage device being locked so as to no longer accept any user code, the method comprising:

receiving an administrator code;

authenticating the administrator code;

decoding a master code;

providing access to a master file system comprising a user encryption key for data stored within the locked secure USB storage device based on the master code; and

resetting a lockout parameter of the locked secure USB storage device, thereby permitting acceptance of a user code.

16. The method of claim 15 , wherein the locked secure USB storage device comprises a locked detachable secure USB storage device.

17. The method of claim 15 , wherein the locked secure USB storage device comprises the master code.

18. The method of claim 15 , wherein the locked secure USB storage device further comprises a user file system.

19. The method of claim 15 , further comprising:

receiving a user code; and

decrypting the user encryption key using the user code.

20. The method of claim 15 , wherein authenticating the administrator code comprises detecting an administrator secure USB storage device.

21. The method of claim 20 , further comprising verifying the administrator code.

22. The method of claim 15 , wherein resetting the lockout parameter of the locked secure USB storage device comprises resetting a number of consecutive user code attempts.

23. The method of claim 15 , wherein resetting the lockout parameter comprises receiving a new user code from the administrator.

24. The method of claim 15 , wherein resetting the lockout parameter of the locked secure USB storage device comprises providing the user encryption key to an administrator.

25. The method of claim 24 , wherein the user encryption key is encrypted by a user code.

26. The method of claim 24 , wherein the user encryption key is encrypted by an administrator encryption key.

27. The method of claim 15 , wherein resetting the lockout parameter comprises providing a master encryption key for the locked secure USB storage device to an administrator based on the master code.

28. A computer readable non-transitory storage medium having embodied thereon a program, the program being executable by a processor for performing a method for recovery of data access of a secure Universal Serial Bus (USB) storage device, the secure USB storage device being locked so as to no longer accept any user code, the method comprising:

receiving an administrator code;

authenticating the administrator code;

decoding a master code;

providing access to a master file system comprising a user encryption key for data stored within the locked secure USB storage device based on the master code; and

resetting a lockout parameter of the locked secure storage device, thereby permitting acceptance of a user code.
