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.

Bench HiAE on your machine

gcc -O3 -march=native -I code code/*.c test/performance_test.c -o perf_test
./perf_test

Applications

HiAE-HMAC

The File verification with HiAE MAC mode.

compile

gcc -O3 -march=native -I code code/*.c app/HiAE-MAC.c -o HiAE-MAC

Usage

./HiAE-MAC <input_file> <key> <iv> [buffer_size (MB)]

Example

$ ./HiAE-MAC README.md 1926 0817
KEY = 1926000000000000000000000000000000000000000000000000000000000000
IV = 08170000000000000000000000000000
MAC: c9e1326675a5e70c3609c8eacfe89b83
MAC file README.md (2079 bytes) in 0.000100 seconds
Speed: 0.019362 GB/s

File AEAD Encryption & Decryption

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

compile

gcc -O3 -march=native -I code code/*.c app/HiAE-File-AEAD.c -o HiAE-File-AEAD

Usage

./HiAE-File-AEAD <encrypt/decrypt> <input_file> <output_file> <key> <iv> [buffer_size (MB)]

Example

$ ./HiAE-File-AEAD encrypt README.md README.enc 1926 0817
KEY = 1926000000000000000000000000000000000000000000000000000000000000
IV = 08170000000000000000000000000000
Encrypted README.md to README.enc (2079 bytes) in 0.000178 seconds
Speed: 0.010878 GB/s

$ ./HiAE-File-AEAD decrypt README.enc README.md 1926 0817
KEY = 1926000000000000000000000000000000000000000000000000000000000000
IV = 08170000000000000000000000000000
Authorization Passed.
Decrypted README.enc to README.md (2079 bytes) in 0.000220 seconds
