Abstract (en)
A security device 16 for deterring theft of the equipment 10 into which it is incorporated is embedded in an ASIC 11 which controls many of the functions of the equipment 10. The security device periodically implements a challenge/response routine with a remote security centre 20. If the appropriate response is not received, the security device 16 disables the ASIC 11, so that the equipment 10 does not operate properly. On detecting theft of the equipment 10 the user contacts the security centre to hold the response when next challenged. <IMAGE>
