One of the strengths of the Cryptography Group at Royal Holloway is to design and formally analyse the security of a variety of cryptographic protocols.

This is typically done within the framework of provable security, a modern cryptography approach which allows to reason about the security guarantees of a scheme or protocol using formal definitions and rigorous proofs.

Our expertise in this area includes design and analysis of public-key encryption primitives, digital signature schemes and primitives with advanced functionalities (such as verifiable delay functions), and more complex, multi-party protocols such as secret sharing schemes, reputation systems and e-voting schemes.
