A system may include a cryptographic accelerator to generate a first check value based on a payload received in a message, and provide the first check value to a first comparator and to a second comparator. The system may include the first comparator to receive the first check value from the cryptographic accelerator, determine whether the first check value matches a second check value, the second check value being a check value received in the message, and provide a first output indicating whether the first check value matches the second check value. The system may include the second comparator to receive the first check value from the cryptographic accelerator, determine whether the first check value matches the second check value, and provide a second output indicating whether the first check value matches the second check value.
