Security and Data Privacy in MPC
มุมมอง 875ปีที่แล้ว
So far in these videos, we've been assuming that the three people running the MPC are all honest, trustworthy people. But what if one of them wasn't honest but actually an imposter? In this video, we demonstrate that a single imposter can still not violate privacy.
How Multiplication in MPC works
มุมมอง 992ปีที่แล้ว
In this video, we try to deep-dive into how and why multiplication works. We try to explain it using two approaches i.e. a visual approach and another using basic math. We also explain why we need masking and how it is included while doing multiplication in MPC
Introducing Multiplication in MPC
มุมมอง 1.1Kปีที่แล้ว
Key Learnings - It is possible to multiply two numbers, without ever learning what they are - The helper parties do not even learn the answer, as they compute a secret-sharing of the answer - Each helper just needs to do some simple addition and multiplication - There is a step called "Masking" which involves generating random numbers - At the end, each helper writes a number down and shares it...
How addition in MPC works
มุมมอง 1.5Kปีที่แล้ว
In this video, we try to explain how addition works in MPC on a whiteboard. We use a visual approach by showing shares of numbers as line segments and adding them up
Introducing Secure Multi Party Computation (MPC)
มุมมอง 3.9Kปีที่แล้ว
In this video, we explain what "secret-sharing" is in a simple, approachable way. We also show how you can add up secret-shared numbers. Key learnings 1. If you only have 2 out of 3 secret-shares, you learn nothing about the secret number 2. With multiparty computation (MPC) we can add up secret-numbers to find the total, without learning what they are. 3. Actually, you can compute any function...
how can graphs be integrated in MPC ?
Great video
Thanks man 🙂 Thank you all
Brilliant!
Excellent content
Interesting!
why isn't this on some magic show? 😅
Hi. Thank you for such a clear explanation. Can you make a video explaining how to find max value using MPC i.e. the millionare's problem?
How 9+8+1 will be 8!?
thats what I wanna know too. Isn't it 18?
Ooh I get it now they are not talking about the literal addition, they are adding them on biclock, which has only 0-9 numbers on it. 9+1=0 => 0+8=8. :)
magic
I want to know about how commuication is done in smpc?
video is great
what if if it's only two running the MPC??
Do the parties involved in the computation have to always be 3? Can the number of parties be increased or reduced to 2?
Computers communicate with each other through the internet
The cost of sending data across data centers is the most expensive part of MPC
Therefore when designing MPC protocols, we usually minimize the number of multiplication
Addition is almost free
Biclock- modulous
Discuss under what conditions the privacy would be preserved or compromised
Masking
Security, privacy. Is possible to do all kinds of computations without learning all the secret inputs
This is an AMAZING series so far. Your pacing could not be better.
But what if the two bad ones collaborate 😂?
If that happens, the protocol will break and privacy will be violated. That's why it is important to choose the helpers carefully and impose rules such that it would be not worth it for them. Please watch the next video to learn more
Honest and trustworthy people. What if not?
I just found your videos, you are a genius, and make things much easier. Thanks
Hey, your explanation is the best. I am a Quantum secure multi party student and I enjoyed this vide
*PromoSM* 😁
good job explaining this in a simple and fun way
