At the National Cyber Security Centre (NCSC), we focus on designing cryptography primarily for scenarios that demand long-term security or involve sensitive data, which leads us to adopt a very cautious approach to its implementation. The security needs we cater to are often mirrored in numerous commercial contexts; however, not all cryptographers may align with our decision-making priorities. For instance, we typically advocate for simplicity in design, even if it may incur some performance trade-offs.
We believe that our cryptographic designs will resonate with those facing similar challenges, and our paper outlines potential avenues for future exploration. We would be delighted to witness others expanding upon our findings. If you’re eager to delve deeper into the specifics, we encourage you to view the paper on the International Association for Cryptologic Research website.
