A list of puns related to "Secure multi party computation"
Hi, I have a homework about multi party computation but the teacher didn't really give us a class on it and I'm really confused about a couple things, namely how 1-2 OT can be seen as an instance in smpc and how it's a building block in Bit Commitment.
I tried looking on the internet but the resources I found were either really vague or way too specific and complex, and I'd appreciate if someone could explain it to me!
TinySMPC is a tiny, educational SMPC library.
The tutorial runs in your browser for those who want to learn. The implementation is designed for understandability, for those who want to fiddle around in the source (pure Python, zero dependencies).
It currently covers additive secret sharing, SPDZ, and (part of) SecureNN.
If you're interested in secure multi-party computation, check it out!
(Disclaimer: This library is strictly "rolled my own crypto", and not designed for secure production use cases. It's only for education.)
Before I start my ramble about; why sMPC is great, what fuels it and what it can achieve, I'll give a little background info about myself.
I've worked for CBS (Central Bureau for Statistics) or Statistics Netherlands during my 6 month internship, researching sMPC in the context of creating a new way to handle and create statistics. I've been in contact with 3 of the most prominent sMPC supplying companies and have asked away to my hearts contents.
I'll start with an anecdote that involves a famous problem and easy to understand use-case, "The Millionaire problem".
Let's say there are 5 individuals named Jon, Vincent, Kale, Trevor and Bob. Jon, Vincent, Kale and Trevor (JVKT for short) are all millionaires and live a wealthy life. The JVKT millionaires are rather rich but don't know who's the richest of them all. However, they don't want to show each other how much they each specifically have. That's where Bob comes in. Let's say Bob is incorruptable and therefore unbribable and will always supply the correct answer and never leak data.
The JVKT millionaires each supply their balance numbers to Bob, consequently trusting Bob not to leak any data or give a false answer. Bob computes the answer for the millionaires by comparing how much each party has, after comparing the numbers Bob provides the answer on which millionaire has the most money. No exact number was provided only a name was provided as an answer by Bob.
In short; trust should not be the driving force behind this scenario, instead it's alot better to rely on a mathmatically proven and correct protocol to deal with computing the answer. This protocol can then be peer reviewed extensively by peers, meaning the factor of trust is mitigated and no longer necessary since the protocol can be reviewed by anyone.
The exact same scenario as before now takes place, but instea
... keep reading on reddit β‘You can see a good explanation for SMPC here: https://en.wikipedia.org/wiki/Secure_multi-party_computation#Yao-based_protocols. I suppose there's also homomorphic encryption.
It's claimed as being for "distributed voting, private bidding and auctions, sharing of signature or decryption functions and private information retrieval." As near as I can tell, the method can ensure CPUs only work with encrypted data. If all the data sent to the CPUs is encrypted would it still be possible to perform exploits against them even if they were vulnerable to the exploits?
Admittedly, I suppose they could still be vulnerable if the info being routed to them actually contained the exploits. An addendum: would it be possible to overcome that with less complex/vulnerable hardware in the routers that'd only minorly change the data coming in from the ISP? I guess we could assume the OS being used is seL4 so we're not worrying to much about OS exploits existing regardless? Sorry if these are dumb questions.

We welcome all the crypto enthusiasts to join Lumino. From June 21 to August 20, a 60-day Multi-Party Computation will be scheduled to produce secure parameters for PlatON, Alaya, and other zero-knowledge proofs-based decentralized infrastructures.
Lumino is a sequential computation by involving as many people as possible to contribute their randomnesses in turn. The result is mathematically guaranteed if at least one person behaves honestly. As LatticeX foundation, we will reserve around 40 google cloud machines for Lumino participants. By following a first-come-first-serve (FCFS) strategy, applicants can indicate their interest to use the google cloud machine in the registration email. We will notify you with instructions via a follow-up email once the application is confirmed.

Out of curiosity, I followed the Cryptography 6.875 MIT Course (link). After that I became interested in MPC and started reading "A Pragmatic Introduction toSecure Multi-Party Computation".
I am wondering how can I implement these schemes (for understanding purposes only, I am looking for production level code). Also, how should I make progress in this field?
I want to make something like this but without straight away copying. https://github.com/kennysong/tinysmpc/. Please give me some pointers on how to approach this problem.
Do let me know if/how to improve this post or if you need any further information.
I'm looking for a scheme that allows n parties to establish a secret shared permutation f(x) of 1..n such that each participant P_i only knows f(i) (i.e, establish a unique secret index for each party).
I'm not sure whether this is even possible at all as I'm not that familiar with MPC / OT / ZKP etc. Seems to me like it could be useful for voting schemes, so I imagine some work has been done on this. The only semi solution I've come up with is vulnerable to collusion.
Thanks in advance!
Edit: didn't read it yet, but this seems promising
Does anyone know of a protocol for secure multiparty computation for three parties, all of which could be malicious?
I was looking at this but it says in the paper that it's only secure for one of the three parties being malicious.
