A mechanism for protecting integrated circuits (IC) from security attacks includes an IC having components that may store one or more data items and may perform a number of functions and which produce resulting events. The IC may also include a security module that may modify signals and events provided to the components such that the resulting events are modified in a non-effectual way but that causes the events to be non-deterministic relative to an event that is external to the integrated circuit when the resulting events are viewed externally to the IC. This may result in obscuring the data, and the functions from being observed from external to the IC, particularly when using an IR laser probe.
