Final Report Abstract

The goal of this project was to design efficient and secure symmetric cryptographic primitives, considering countermeasures against physical attacks. As a result, we introduced three different block ciphers, each optimized for specific applications. The first block cipher, CRAFT, is optimized to provide protection against fault-injection attacks with minimal overhead. Next, we introduced SPOOK, designed to offer security against side-channel attacks at a low energy cost. SPEEDY is the last block cipher, an ultra-low-latency block cipher designed for use in secure caches or other applications requiring high-speed encryption. In the next step, taking CRAFT into account, we proposed several methodologies to provide protection against fault-injection attacks based on linear codes. Additionally, we provided a tool to verify the security of a design against fault-injection attacks under different attacker models. We also introduced novel techniques to reduce the overall cost of masking schemes in hardware platforms, particularly in terms of fresh randomness and latency, measured in the number of clock cycles.
