Abstract

A system embodiment associated with making a computer a less desirable target for a thief is described. A system embodiment may include a security timer that is to be periodically refreshed. If the security timer is not periodically refreshed, then a computer in which the system embodiment is located may be disabled by a theft deterrence logic. The system embodiment may also include a communication logic to communicate with a TDSP to request a signal to update the security timer. While a system embodiment is described, it is to be appreciated that other system embodiments having different elements and that method embodiments may be described.

Claims

1. A system, comprising:

a security timer;

a communication logic to communicate with a theft deterrence service provider (TDSP) to request a signal to update the security timer; and

a theft deterrence logic to disable a computer associated with the system, the theft deterrence logic to disable the computer upon the expiration of the security timer,

at least one of the security timer, the communication logic, and the theft deterrence logic being part of an integrated embedded controller (IEC), the IEC being a member of a chipset of the computer.

2. The system of claim 1, where the theft deterrence logic is to periodically request the signal to update the security timer.

3. The system of claim 2, where the TDSP will not provide the signal to update the security timer upon determining that the computer housing the system has been stolen.

4. The system of claim 3, the IEC being implemented in microcode.

5. The system of claim 4, where the security timer, the communication logic, and the theft deterrence logic are part of the IEC.

6. The system of claim 1, the communication logic to communicate with the TDSP using one or more of, an out-of-band path not associated with an operating system associated with the computer, or an in-band path utilizing the operating system to relay messages between the theft deterrence logic and the TDSP.

7. The system of claim 1, the signal being a cryptographically signed and encrypted absolute time value.

8. The system of claim 7, the TDSP to re-enable the computer by providing an enabling key.

9. The system of claim 8, the enabling key being an absolute time value.

10. The system of claim 1, the communication logic to encrypt communications from the theft deterrence logic to the TDSP.

11. The system of claim 10, the communication logic to encrypt communications to the TDSP using Public Key Infrastructure (PKI).

12. A method, comprising:

examining a security timer of an IEC implemented at the microcode level in a chipset of a computer;

requesting from an external security provider a signal to update the security timer; and

disabling the computer upon determining that the security timer has expired.

13. The method of claim 12, including:

receiving the signal to update the security timer; and

updating the security timer.

14. The method of claim 13, including:

encrypting a message requesting the signal to update the security timer; and

communicating the message to the external security provider using an out-of-band path.

15. The method of claim 14, including:

receiving an enabling key from the external security provider; and

re-enabling a previously disabled computer based, at least in part, on the enabling key.
