01 02 Verified Pythagorean Composition for Adaptive Cryptographic Games: Noise Flooding in Homomorphic Encryption eprint.iacr.orgDoes noise flooding in approximate HE actually compose? This paper machine-checks a square-root-loss proof in Rocq.03 Can Lean model game hops and extract reductions? HOPSCOTCH says yes, with mechanized IND-CCA, ElGamal, and GGM proofs.04 Two-limb CRT Ring-LWE PKE with exact decryption and public rerandomization, plus no ciphertext growth, because noise needed a sequel.05 MOSAIC-FL, a micro-service based privacy-preserving framework with application to genomics arxiv.orgMicroservices plus threshold CKKS for federated genomics, with an FSM for sync and threat detection, because plain FL wasn't enough.
