PALISADE Webinar #4 - HE Tutorial Series Part 5: Introduction to Multiparty Homomorphic Encryption
Channel: PALISADE Homomorphic Encryption Library
Date: 31/10/2020

This talk by Yuriy Polyakov, a PALISADE co-founder and project lead, is the fifth part of the miniseries "Homomorphic Encryption for PALISADE Users: Tutorial with Applications". The talk introduces multiparty homomorphic encryption and explains how to use it in PALISADE.

The expected audience is anyone interested in lattice-based crypto, homomorphic encryption and/or its applications, with a focus on application developers, engineers, researchers and students.

The webinar includes interactive Q&A and discussion.  We intend for this webinar series to be monthly, with future webinars episodes on the theory behind lattice crypto and FHE, deep-dives on the use of PALISADE for real-world applications, software engineering for cryptography, and more.
