Abstract
An IC comprising functional circuit to perform primary functions of the IC is provided. The functional circuit is to enable electrical signals to propagate through it within a timing constraint of the functional circuit. The IC comprises at least one canary circuit used for detecting glitch attacks on the circuit. Electrical signals are to propagate through the canary circuit(s) within a defined timing constraint of the canary circuit(s). The canary circuit is to provide a signal path designed such that in the event of a timing constraint of the functional circuit(s) is violated due to a glitch attack, also the timing constraint of the canary circuit(s) is violated.
