Structured Encryption Scheme Design
Research direction in searchable/structured encryption and efficient scheme design.
This project page summarizes my ongoing PhD research in applied cryptography, focused on structured encryption (STE), encrypted multi-maps, and volume-hiding systems.
Current work includes:
- Implementing and benchmarking volume-hiding STE/EMM constructions, including the computational volume-hiding line initiated by Kamara & Moataz (Eurocrypt 2019). ([ACM Digital Library][1])
- Implementing VH-EMM variants based on hashing techniques (incl. cuckoo hashing) and evaluating their real-world efficiency/engineering tradeoffs, following later dynamic volume-hiding EMM work (e.g., Amjad et al.). ([ePrint Archive][2])
- Subliminal EXH (my work): designing and implementing a queueing-theory–inspired mechanism to mitigate volume leakage under realistic query patterns.
- Multi-server volume-hiding settings: studying distributed threat models, identifying an impossibility result under the volume-hiding definition we use, and proposing alternative construction ideas. This work is part of an ongoing submission tentatively titled On the Cost of Volume Hiding Schemes.
As publications and artifacts mature, this page can be expanded with implementation notes, benchmarks, and reproducible evaluation results.
