First Claim
Patent Images
1. An apparatus secured to a device, comprising:
- a fastener;
an adhesive secured to the fastener;
an electric circuit configured to measure a property;
a memory configured to store the property; and
at least one Key to access the stored property,wherein if the device is tampered with when the device is powered off, the apparatus is configured to detect the tampering of the device when the device is powered back on,wherein the device is a wireless network equipment,wherein the memory is configured to receive and store an encrypted log file that includes a special NULL value,wherein when the special NULL value is read, the apparatus is temporarily disabled from detection of tampering to allow authorized access of the device, andwherein the apparatus is re-enabled to detect tampering after a new encrypted log file containing a new measured property is received and stored in the memory.

12. A method for detecting tampering of a device, the method comprising:
-
measuring a reference property value of a circuit; storing the reference property value of the circuit in a device; measuring a current property value of the circuit; comparing the reference property value of the circuit to the current property value of the circuit; and initiating an alarm at the device if the current property value does not match the reference property value, wherein the alarm indicates that the device has been tampered, wherein if the device is tampered with when the device is powered off, the method further comprises detecting the tampering of the device when the device is powered back on, wherein the device is a wireless network equipment, wherein the method further comprises receiving and storing an encrypted log file that includes a special NULL value, reading the special NULL value, after the special NULL value is read, temporarily disabling tempering detection of the device to allow authorized access of the device, while tampering detection has been temporarily disabled, receiving and storing a new encrypted log file containing a new measured property, and after receiving and storing the new encrypted log file, re-enabling tempering detection of the device. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A system for tamper detection comprising:
-
a device in a telecommunications network; and an apparatus secured to the device, the apparatus comprising; a fastener; an adhesive secured to the fastener; an electric circuit configured to measure a property; and at least one Key configured to access the property value, wherein the property value is stored on the device; wherein the apparatus is configured to; measure a reference property value of the circuit; store the reference property value of the circuit in the device; measure a current property value of the circuit; compare the reference property value of the circuit to the current property value of the circuit; and initiate an alarm at the device if the current property value does not match the reference property value, wherein if the device is tampered with when the device is powered off, the apparatus is further configured to detect the tampering of the device when the device is powered back on, wherein the device is a wireless network equipment, and wherein the apparatus is further configured to receive and store an encrypted log file that includes a special NULL value, read the special NULL value, after the special NULL value is read, temporarily disable tampering detection of the device to allow authorized access of the device, while tampering detection has been temporarily disabled, receive and store a new encrypted log file containing a new measured property, and after receiving and storing the new encrypted log file, re-enable tempering detection of the device. - View Dependent Claims (20)
