May the Force Not be With You: Brute-Force Resistant Biometric Authentication and Key Reconstruction

Deep Inder Mohan, Sasha Boldyreva, Tianxin Tang

A biometrics-based key storage and retrieval system that requires no memorized secret beyond the user's own biometric template. Combines Fuzzy Vaults and Oblivious Pseudorandom Functions to achieve provable security against online and offline brute-force attacks under a variety of corruption scenarios. Also presented at the BioAuthSec workshop at ASIACRYPT 2025 and as a poster at RSA Conference 2024.

Generic and Algebraic Computation Models

Deep Inder Mohan, Joseph Jaeger

A new framework for the Algebraic Group Model (AGM) enabling security proofs to transfer directly from the AGM to the Generic Group Model (GGM) under certain conditions. Resolves logical discrepancies in Fuchsbauer et al.'s AGM framework and supports multiple formalisms for easier proof-writing. Also presented as an invited talk at the CWI Amsterdam cryptology seminar.

Secure Identity Verification Using Cloud Services and FHE

Deep Inder Mohan, Srinivas Vivek

A prototype for a practically deployable identification platform that delegates all computation and storage to third-party nodes, developed in collaboration with MOSIP. Implemented in C++ using the Microsoft SEAL FHE library. Accepted as a talk at the Trustworthy Digital Identity Conference by the Alan Turing Institute, London.

Modelling Prejudice and Its Effect on Societal Prosperity

Deep Inder Mohan, Shrisha Rao

An agent-based model simulating inter-group prejudice in society to study changes and disparities that may arise among groups over time. Published in the Journal of Simulation.
