Abstract

An integrated circuit (IC) package includes a storage element and a protection component coupled to the storage element. The protection component includes a breach detection component configured to detect an attempted breach of the IC package. The protection component further includes a time detection component configured to determine a breach timestamp associated with a time of occurrence of the attempted breach and configured to store a representation of the breach timestamp in the storage element. The storage element may be configured to store a sensitive datum, and the time detection component may be configured to store the representation of the breach timestamp by overwriting the sensitive datum in the storage element with the representation of the breach timestamp.
