Abstract
Energy efficiency, limited power consumption and increased performance will drive the design of new architectures and arithmetic units. Unconventional number systems, namely Residue Number Systems (RNS), and modular arithmetic may hold the answer to these emerging challenges. In this talk we show how to use the RNS to improve cryptographic algorithms and engines, making them more efficient and more resistant to side-channel attacks, not only in the context of traditional cryptography but also of emerging post-quantum cryptography. Moreover, the potential of RNS to support the high-performance implementation of deep convolutional neural networks (DCNNs) is unveiled. Emerging technologies are also targeted in this talk, namely the implementation of RNS arithmetic units with reversible logic to improve density, speed and energy efficiency.
