Abstract
A device may compute a cryptographic state based on a freshness value. The device may compute a successive cryptographic state based on a successive freshness value. The successive freshness value may be based on a freshness modifier in combination with the freshness value. The device may store the cryptographic state and the successive cryptographic state. The device may receive a message after the cryptographic state and the successive cryptographic state are stored. The device may identify the cryptographic state or the successive cryptographic state based on the freshness value or the successive freshness value. The device may perform a security operation based on the cryptographic state or the successive cryptographic state.
