Introduction to CKKS (Approximate Homomorphic Encryption)

The Private AI Bootcamp offered by Microsoft Research (MSR) focused on tutorials of building privacy-preserving machine learning services and applications with homomorphic encryption (HE). Around 30 PhD students were invited to gather at the Microsoft Research Lab in Redmond on Dec 2nd - 4th, 2019. The program contents were specifically designed for training. Participants mastered the use of HE, the Microsoft SEAL library, and the methodology behind building privacy-preserving machine learning solutions. As a project as well as a competition, students worked in teams, designed and pitched a novel technology built upon what they had learned during the bootcamp, and received feedback and scores from experts. There was a secret prize for the winning team. There were also social events where all participants had a chance to meet and network with other PhD students and experts from MSR.

Hi, could you please make the slide deck available? It would really help.

hi, at 7:03, how to find the coefficients of the m(X)?
I mean, how to find 435, -706, 282, -308? what's the algorithm to find these coefficients?

Could anyone suggest some other videos (or some other presenters) that introduce CKKS? I have found some videos, but all are presented by the same person. I didn't mean his presentation is bad, actually he would be the best presenter as he is the author. As I am a non-native English speaker, I found it very difficult for me to understand what he said.I know it is my problem, but I really want to understand the details. Thanks.

find some videos and blogs of MS SEAL, that would help

[@ImtiyazuddinShaik]

why is relinearization a key operation in SEAL library when the same CKKS scheme implemented in HEAAN library doesn't have one?

[@jonabirdd]

That's because they implement it as an integral part of the multiply operation

[@macknightxu2199]

@@jonabirdd I guess you mean rescaling, not relinearization. But the question is for why there's no relinearization in HEAAN.

Thank you so much for sharing the video. The video is really helpful. However, I am getting an error at no seal/seal.h file found. How to execute code? Sir, This will be a great help for all here If you share.
