Adding more parallelism to the AEGIS authenticated encryption algorithms

ePrint Report: Adding more parallelism to the AEGIS authenticated encryption algorithms

Frank Denis

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.
