ePrint Report: HRA-Secure Homomorphic Lattice-Based Proxy Re-Encryption with Tight Security
Aloni Cohen, David Bruce Cousins, Nicholas Genise, Erik Kline, Yuriy Polyakov, Saraswathy RV
We construct an efficient proxy re-encryption (PRE) scheme secure against honest re-encryption attacks (HRA-secure) with precise concrete security estimates. To get these precise concrete security estimates, we introduce the tight, fine-grained noise-flooding techniques of Li et al. (CRYPTO'22) to RLWE-based (homomorphic) PRE schemes, as well as a mixed statistical-computational security to HRA security analysis. Our solution also …
