Adding more parallelism to the AEGIS authenticated encryption algorithms
Abstract
While the round function of the AEGIS authenticated encryption algorithms is highly parallelizable, their mode of operation is not. We introduce two new modes to overcome that limitation: AEGIS-128X and AEGIS-256X, that require minimal changes to existing implementations and retain the security properties of AEGIS-128L and AEGIS-256.
Note: Version 1.1. Includes additional test vectors, additional benchmark results, and clarifies the finalization step.
