FUSE-BASED ANTI-REPLAY MECHANISM

Techniques for providing data protection in an integrated circuit are provided. A method according to these techniques includes maintaining an anti-replay counter value in a volatile memory of the integrated circuit, the anti-replay counter value being associated with data stored in an off-chip, non-volatile memory in which the integrated circuit is configured to store the data, monitoring an external power source, and writing the anti-replay counter value to a programmable read-only memory of the integrated circuit responsive to a loss of power to the integrated circuit from the external power source.
