Mastic: Private Weighted Heavy-Hitters and Attribute-Based Metrics

FuseFSS: Efficient Secure LLM Inference with Function Secret Sharing — ICML 2026. Compiler, CUDA runtime, and Sigma integration.

Privacy-preserving recommender in C++17: three-server private matrix factorisation (Nudge) composed with DPF-based private retrieval (Pirsona), with the cost and leakage of the composition measured. No cryptographic libraries.

Browser-based two-server PIR from distributed point functions — tree expansion, a 65,536-record private shelf, key-size comparison, collusion, and tampering side by side, with real AES-128-CTR seeds and a 290-byte key against the 8,192-byte full-domain XOR baseline.
