WebMar 1, 2024 · The Galois/Counter Mode of operation GCM is a widely used nonce-based authenticated encryption with associated data mode which provides the birthday-bound security in the nonce-respecting scenario; that is, it is secure up to about 2n/2 adversarial queries if all nonces used in the encryption oracle are never repeated, where n is the block … WebBroadwell architecture. On Broadwell, GCM-SIV encryption takes only 0.92 cycles per byte, and GCM-SIV decryption is exactly the same as GCM decryption taking only 0.77 cycles per byte. In addition, we compare to other optimized authenticated-encryption implementations carried out by Bogdanov et al., and conclude that our mode is very competitive.
