Abstract

Various devices may benefit from enhanced security. For example, secure storage devices and authentication devices may benefit from security that permits isolation of the devices from the operating system and data ports of a host computer. An apparatus can include a first interface configured to connect to a non-volatile storage device. The apparatus can also include circuitry configured to supply an encryption key over the first interface to decrypt data on the non-volatile storage device. The first interface is configured to connect directly to the non-volatile storage device.

Claims (49)

1 . An apparatus, comprising:

a first interface configured to connect to a provided non-volatile storage device; and

circuitry configured to supply an encryption key over the first interface to decrypt data on the provided non-volatile storage device,

wherein the first interface is configured to connect directly to the provided non-volatile storage device.

2 . The apparatus of claim 1 , further comprising:

a memory configured to store a key or an encrypted key, wherein the key or the encrypted key is supplied as the encryption key.

3 . The apparatus of claim 1 , further comprising:

an additional interface configured to connect to at least one of a provided keyboard or a provided biometric device.

4 . The apparatus of claim 1 , wherein the circuitry of the apparatus is further configured to receive a password from an additional interface and at least one of supply the encryption key based on the received password or supply the password to the provided non-volatile storage device.

5 . The apparatus of claim 1 , further comprising:

an erase element, wherein the erase element is configured to trigger the provided non-volatile storage device to erase itself when the erase element is inserted directly into the provided non-volatile storage device.

6 . The apparatus of claim 1 , further comprising:

a second interface comprising a serial port.

7 . The apparatus of claim 1 , further comprising:

at least one light emitting diode or a display configured to indicate a status of the apparatus.

8 . The apparatus of claim 7 , wherein the status of the apparatus comprises a status of at least one of a password, a key and entered data.

9 . The apparatus of claim 1 , further comprising:

at least one of a radio frequency receiver and a global positioning system device, wherein the apparatus is configured to further authenticate based on detecting a specific radio frequency signal or physical location.

10 . The apparatus of claim 1 , further comprising:

a removable battery configured to erase a key stored in the apparatus by powering off the apparatus when removed.

11 . A system, comprising:

a non-volatile storage device comprising a first interface to a provided host computer and a second interface away from the provided host computer;

a crypto key device comprising a third interface configured to connect to the second interface of the non-volatile storage device and circuitry configured to supply an encryption key over the third interface to decrypt data on the non-volatile storage device,

wherein the third interface is configured to connect directly to the second interface.

12 . The system of claim 11 , wherein the circuitry of the crypto key device is further configured to receive a password from an additional interface and supply the encryption key based on the received password.

13 . The system of claim 11 , further comprising:

at least one of a keyboard or a biometric device, wherein the at least one of the keyboard or the biometric device is configured to connect to the crypto key device at a fourth interface.

14 . The system of claim 11 , further comprising:

a key fill device, wherein the key fill device is configured to at least one of connect to the crypto key device at a fourth interface or connect to the non-volatile storage device at the second interface.

15 . The system of claim 11 , further comprising:

an erase element, wherein the erase element is configured to trigger the non-volatile storage device to erase itself and/or erase encryption keys when the erase element is inserted directly into the non-volatile storage device.

16 . The systems of claim 11 , wherein the non-volatile storage device is configured to use a laptop bay of a removable compact disk or digital versatile disk drive.

17 . The system of claim 11 , wherein the non-volatile storage device is configured to perform encryption and multi-factor authentication.

18 . The system of claim 11 , wherein the non-volatile storage device is configured to perform authentication without intervention or interaction of the provided host computer.

19 . The system of claim 11 , wherein the non-volatile storage device comprises a solid state drive.

20 . The system of claim 11 , wherein at least one of the second interface or the third interface comprises a serial port.

21 . The system of claim 11 , wherein the crypto key device further comprises at least one light emitting diode or display configured to indicate a status of the crypto key device.

22 . The system of claim 21 , wherein the status of the crypto key device comprises a status of at least one of a password, a key, or entered data.

23 . The system of claim 11 , wherein the crypto key device further comprises a radio frequency receiver or a global positioning system device, wherein the crypto key device is configured to further authenticate based on detecting a specific radio frequency signal or physical location.

24 . The system of claim 11 , further comprising:

a fixed circuit provided electrically between the non-volatile storage device and the host computer, wherein the fixed circuit is configured to be detectable by the non-volatile storage device.

25 . A method, comprising:

powering on a secure storage device using a host computer; and

authenticating access to the secure storage device using at least one key,

wherein the authenticating bypasses an operating system and a basic input/output system of the host computer.

26 . The method of claim 25 , further comprising:

providing at least one key to the secure storage device from a crypto-key device connected directly to the secure storage device.

27 . The method of claim 25 , further comprising:

destroying or permanently disabling the secure storage device by inserting a magnetic erase stick into a port configured to receive the magnetic erase stick, wherein the port is configured to be in close proximity to magnetic random access memory of the secure storage device.
