CryptoHDL

A list of VHDL codes implementing cryptographic algorithms

Motivation

The motivation of creating this repository is to have a centralized point where all VHDL implementation of cryptographic algorithms can be found. I do my best to keep it updated. If you find or have any VHDL implementation of cryptographic algorithm that are missing, don't hesitate to contribute.

AES

VHDL implementation of AES encryption, and decryption algorithms

There are simple VHDL implementations of AES-128 encryption, and decryption algorithms, in this repository. This is actually my first experience in VHDL implementation! (https://hadipourh.github.io/AES-VHDL/).

This repository includes the hardware designs of AES cipher

There are 3 folders for the VHDL source code of different implementations of AES. Apart from the unprotected implementation, all other designs MUST be synthesized by "keeping the hierarchy". Otherwise, no fault-detection and no protection against SCA is guaranteed.

Unrolled hardware implementation of AES-128-128

This work compares unrolled combinational hardware implementations of six lightweight block ciphers, along with an AES implementation as a baseline.

Ascon

Energy Efficient Hardware Implementations of Ascon

Energy-efficient implementations of Ascon-128 and Ascon-128a by Michael Fivez, including a comparison with Joltik and MORUS. This repository contains several implementations of the Ascon hardware cipher.

Side-channel protected hardware implementations of Ascon

Side-channel protected hardware implementations of Ascon-128 and Ascon-128a by Hannes Groß using domain-oriented masking.

CRAFT

This repository includes the hardware designs of CRAFT cipher

There are 6 folders for the VHDL source code of different implementations of CRAFT. Apart from the unprotected implementation, all other designs MUST be synthesized by "keeping the hierarchy". Otherwise, no fault-detection and no protection against SCA is guaranteed. (https://sites.google.com/view/craftcipher/implementation).

Hardware implementation of CRAFT secured against Statistical Ineffective Fault Attack (SIFA) attack

This repository contains the HDL code and analysis results for hardware designs described in the paper: "Impeccable Circuits II" authored by Aein Rezaei Shahmirzadi, Shahram Rasoolzadeh, and Amir Moradi. Ruhr University Bochum, Embedded Security (Germany)
