001 Introduction to Homomorphic Encryption w/ Pascal Paillier

Abstract
Pascal Paillier gives an introduction lecture to homomorphic encryption (FHE), include some of the most recent techniques and applications.
About the Speaker
Pascal is a researcher and entrepreneur in cryptography and the CTO at Zama.
He has spent the past 25 years inventing new cryptographic techniques for critical industries. From embedded security to whitebox crypto to homomorphic encryption, Pascal has contributed to groundbreaking research in corporate environments.
He is a member of the IACR and an expert at ISO, where he contributes to standardization efforts for cryptography. Pascal has authored over 60 academic papers, received "Best Paper Award" at Asiacrypt 2005, and is one of the most widely cited authors in homomorphic encryption with more than 12,000 citations. Prior to Zama, Pascal was CEO at CryptoExperts and Head of Cryptography Innovation at Gemalto. He holds an engineering degree and a PhD in cryptography from Telecom ParisTech.

Exceptional presentation! Been working/researching on somewhat same vision. Keep up the great work!

Hi,
May I know if any implementation libs support the bootstrapping operations of CKKS or not?
If yes, where could I find it and its demos or examples.

Thanks for sharing this, how ever i have a question, in the minute 03:30, when talk about other people can contribute, referes to the public encryption evaluation key? if not, what is the use of the encryption eval key? Thanks

Hey there, I would advise that you join the discord server, you'll have answers there: discord.fhe.org :)

Probably the best tutorial I've seen on FHE. Where can I download the actual ppt file? The video bar on the right is super annoying and blocks some key contents ...

I'm confused about bootstrapping; if the server can encrypt the value of X with it's own key. And then decrypt the value of X when it's in Y; aren't both the decryption keys present on the server then? Because that would defeat any confidentiality goals. Or is bootstrapping done client-side?

[@randhindi]

The bootstrapping key is a public key, so the server doesnt need to decrypt anything or have the private keys

[@muhammadhabiburrehman8744]

Thanks Pascal,
It is indeed a great talk, Pascal. Can we use this library for big tensors (containing gradients from NNs)?

[@fhe_org]

Yes that’s the idea! We are working on a framework to help with ML usecases. Coming soon :)

@@fhe_org Thank you very much. Appreciate your good efforts in this very challenging research domain. We are developing a federated learning platform for healthcare operators in London and we will be excited to see the further developments.
