Decentralized Private Steam Aggregation from Lattices

ePrint Report: Decentralized Private Steam Aggregation from Lattices

Uddipana Dowerah, Aikaterini Mitrokotsa

As various industries and government agencies increasingly seek to build quantum computers, the development of post-quantum constructions for different primitives becomes crucial. Lattice-based cryptography is one of the top candidates for constructing quantum-resistant primitives. In this paper, we propose a decentralized Private Stream Aggregation (PSA) protocol based on the Learning with Errors (LWE) problem. PSA allows secure aggregation of time-series data over multiple users without compromising the privacy …
