Multi-architectural 128 bit AES-CBC Core based on Open-Source Hardware AES Implementations for Secure Industrial Communications

In this work we present a new AES-CBC crypto-core for System-on-Programmable-Devices. The core architecture can fit three different open-source AES block implementations. Each one can be instantiated in order to obtain cores with different area-speed trade off, which eases and optimizes the secure communications implementation in industrial embedded systems. The implementation results for the different versions are presented and evaluated.
