NCSC Guidance on “Advanced Cryptography”

A summary of the UK NCSC’s white paper on “Advanced Cryptography,” defining the field and covering techniques like homomorphic encryption, attribute-based encryption, zero-knowledge proofs, and secure multiparty computation, with key guidance to start from clear problem requirements, avoid custom crypto implementations, and weigh current immaturity, performance overheads, and potential new attack vectors; while traditional cryptography often suffices today, ongoing standardization and efficiency gains may enable privacy-preserving data processing use cases in the future.
