HiAE: A High-Throughput Authenticated Encryption Algorithm for Cross-Platform Efficiency

Official implementation of paper "HiAE: A High-Throughput Authenticated Encryption Algorithm for Cross-Platform Efficiency"

Design Rational

The HiAE is an AES-based AEAD cipher that mainly focuses on cross-platform efficiency(ARM and x86) and achieves the fastest speed on the latest ARM and x86 architectures.

Applications

File AEAD Encryption & Decryption

The File encryption will auto append the AEAD tag after the file for integrity protection.

compile

#For x86
gcc -O3 -march=native -I code/ code/HiAE.c app/file_enc.c -o FileHiAE
#For armv8
gcc -O3 -march=armv8-a+crypto -I code/ code/HiAE.c app/file_enc.c -o FileHiAE

Usage

./FileHiAE <encrypt/decrypt> <input_file> <output_file> <key: 32 chars> <iv: 16 chars> [buffer_size: Default 65536]
