AEGIS-128X and AEGIS-256X are proposed variants of the high performance authenticated ciphers AEGIS-128L and AEGIS-256, designed to take advantage of the long pipelines and vectorized AES instructions present on recent CPUs.
AEGIS-128X and AEGIS-256X are now included in the AEGIS specification.
Rationale: Adding more parallelism to the AEGIS authenticated encryption algorithms
List of known opensource AEGIS implementations.
AEGIS-X is at least implemented in libaegis, jasmin-aegis and crypto-rust in addition to the reference implementations.
AEGIS-128X has exceptional performance, even without AVX512.
