Abstract
Techniques for maintaining an anti-replay counter (ARC) for providing data protection in an integrated circuit are provided. A method according to these techniques includes determining a static baseline value based on an ARC value stored in a programmable read-only memory of the integrated circuit, determining the ARC value based on the static baseline value and a transient component, and storing the ARC value in a volatile memory of the integrated circuit.
