Ashley Fraser

Ashley Fraser is a Research Fellow at the DECaDE centre at the University of Surrey, specializing in security and privacy for decentralized digital systems. She holds a PhD in Information Security from Royal Holloway, University of London. Her research focuses on cryptographic primitives for accountability in privacy-preserving technologies, including incoercible signatures, e-voting systems, and blockchain-based identity solutions.

Key contributions include: developing formal security models for e-voting ballot secrecy; designing ring signature schemes with coercibility resistance; and analyzing blockchain's role in self-sovereign identity ecosystems. Methodologically, her work emphasizes game-based security proofs and efficiency optimizations for cryptographic constructions.

Publications demonstrate consistent exploration of tension between privacy and accountability, with recent advances in verifiable signature conversion and malicious-actor resistant systems. Research outputs bridge theoretical cryptography with decentralized application challenges.
