Abstract

A cipher data box comprises: a housing; a printed circuit board; a first connector; a second connector; a controller, having a unique first identification code; a key seat; and a key, having a unique second identification code; therefore, when the key is inserted into the key seat and the first identification code is same as the second identification code, the storage device can be normally accessed, and the data therein will be encrypted/decrypted. Furthermore, for further enhancing the security function of the storage device, a plurality of cipher data boxes of the present invention can be cascade each other.

Claims

1. A cipher data box that can encrypt/decrypt the data of a storage device of a computer or equipment, comprising:

a housing, having a space and at least one opening and a hole;

a printed circuit board, disposed in said space;

a first connector, disposed in said printed circuit board and exposed said opening, for connecting to a storage device;

a second connector, disposed in said printed circuit board and exposed said opening, for connecting to a storage device control circuit of said computer or equipment;

a controller, disposed in said printed circuit board and connecting to said first connector and second connector, respectively, for encrypting/decrypting data of said storage device then outputting, and having a unique first identification code;

a key seat, exposed said hole, and connecting to said controller via wires; and

a key, for inserting into said key seat, having a unique second identification code;

thereby, when said key is inserted into said key seat and said first identification code is same as said second identification code, said storage device can be accessed, and data of said storage device will be encrypted/decrypted.

2. The cipher data box according to claim 1, wherein said housing is made by a metal or plastic material.

3. The cipher data box according to claim 1, wherein said first connector is a SATA, eSATA, IDE, SCSI, Firewire or USIB interface connector.

4. The cipher data box according to claim 1, wherein said second connector is a SATA, eSATA, IDE, SCSI, Firewire or USIB interface connector.

5. The cipher data box according to claim 1, wherein said controller uses DES, TDES or AES protocol to encrypt/decrypt data.

6. The cipher data box according to claim 1, wherein said controller is an ASIC chip.

7. The cipher data box according to claim 1, wherein said printed circuit board further comprises a power jack exposed said hole, for connecting to an external power adapter for providing the necessary power.

8. The cipher data box according to claim 1, wherein said printed circuit board further comprises an indicator disposed on said printed circuit board and coupled to said controller for indicating a status of Power, Cipher key On, as well as HDD Access Status.

9. The cipher data box according to claim 8, wherein said indicator is a multi-color LED or a single color LED;

when said indicator is a multi-color LED, it can indicate said Power, Cipher key On, as well as HDD Access Status by various colors;

when said indicator is a single color LED, it can indicate one of said Power, Cipher key On, as well as HDD Access Status.

10. The cipher data box according to claim 1, wherein a plurality of said cipher data boxes can be cascaded each other by said first connector and said second connector, and when the second identification code of every key is same as said first identification code of every controller, every controller will start to encrypt/decrypt the data to or from said storage device, so that said computer or equipment can normally access the data of said storage device.

11. The cipher data box according to claim 1, wherein said key seat is a mini USB connector.

12. The cipher data box according to claim 1, wherein said key further comprises:

a printed circuit board;

a connector, disposed on the printed circuit board for connecting to said key seat; and

a memory, disposed on the printed circuit board and coupled to said connector for storing said second identification code.

13. The cipher data box according to claim 12, wherein said connector is a mini USB plug.

14. The cipher data box according to claim 12, wherein said memory is a EEPROM, EPROM or a flash memory.

15. The cipher data box according to claim 1, wherein said controller further comprises a memory for storing said first identification code.

16. The cipher data box according to claim 15, wherein said memory is a EEPROM, EPROM or a flash memory.
