snowv-gcm

This crate implements the SNOW-V-GCM AEAD construction.

Installation

[dependencies]
snowv-gcm = "0.1"

Performance

The ARMv8 and x86-64 assembly backends run at about 0.65 cycles per byte. The x86-64 implementation requires SSE2 and PCLMULQDQ instructions. The ARMv8 implementation requires NEON and PMULL.

The defualt Rust implementation will be selected if the CPU does not support either assembly implementation. (This implementation can also be selected with the soft feature.) It is much slower at around 9 cycles per byte.
