ROCCA-S for Rust
This is a Rust implementation of the ROCCA-S: an efficient AES-based encryption scheme for beyond 5G authenticated cipher, ported from the Zig implementation.
ROCCA-S is key committing, has a 256 bit key size, a 128 bit nonce, processes 256 bit message blocks and outputs a 256 bit authentication tag.
Cargo flags
std
: allow dynamic allocations
std
is the default.
IMPORTANT: In order to get decent code on x86 and x86_64 CPUs, you should set
additional rustc
flags prior to compiling that crate or a project using it:
export RUSTFLAGS="-Ctarget-feature=+aes,+sse4.1"
A benchmark can be run that way:
export RUSTFLAGS="-C target-cpu=native -Ctarget-feature=+aes,+pclmulqdq,+sse4.1"
cargo bench
Benchmarks
Benchmarks take a 16384 bytes input block. Results are in bytes per second.
