PALISADE Webinar #3 B - HE Tutorial Series Part 4: Integer Applications
Channel: PALISADE Homomorphic Encryption Library
Date: 2020-10-02

This talk by Dave Cousins, a PALISADE co-founder and project lead, is the fourth part of the miniseries "Homomorphic Encryption for PALISADE Users: Tutorial with Applications". The talk discusses applications of homomorphic encryption over integers, and presents in detail a private substring search application (the public implementation of it is available at https://gitlab.com/palisade/palisade-integer-examples).

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.

The slides for the webinar and more information about PALISADE webinars can be found at https://palisade-crypto.org/webinars/.
