Zusammenfassung:Techniques for providing data protection in an integrated circuit are provided. A method according to these techniques includes exchanging messages with an off-chip, non-volatile memory to securely initialize an anti-replay counter (ARC) value in the integrated circuit based on an ARC value stored in the off-chip, non-volatile memory, and maintaining the ARC value stored in the integrated circuit such that the ARC value stored in the integrated circuit remains synchronized with the ARC value stored in the off-chip, non-volatile memory.
