Abstract
Examples described herein provide a computer-implemented method that includes performing, using a cryptographic accelerator, a cryptographic operation asynchronously relative to a core pipeline. The method further includes computing a chaining value for the cryptographic operation. The method further includes, responsive to an occurrence of an error, recovering from the error using the chaining value.
