Abstract
An intrusion detection circuit may use an element that produces non-repeatable values of a characteristic of the non-repeating element in order to prevent system manipulation. An information handling system may determine a first value for a first characteristic of the non-repeating element coupled to a secure boundary of the information handling system to activate the non-repeating element when the secure boundary is breached; retrieve a second value for the first characteristic of the non-repeating element, where the second value is a previous value compared to the first value; and determine whether an intrusion event occurred by comparing the first value of the first characteristic of the non-repeating element with the second value of the first characteristic of the non-repeating element.
