How to apply Pohlig Hellman using a very limited set of auxiliary inputs in that case ?
So I was reading about [this paper](https://eprint.iacr.org/2024/1321). The underlying idea is to lift the discrete logarithm problem to *prime−1* for prime curves or *order−1* for binary curves since most elliptic curves only have small factors in that case. But [their baby‑step giant‑step variant seems to only work when the private …
Ml-Kem encapsulate non-random bytes?
I am not a cryptographer, but I am trying to use cryptographic libraries and would like to do it safely. Unfortunately, for my use case it seems to require using them in a non-standard way. The APIs don't seem to fit my use case straight-forward. I was curious if it …

Proof of Possession: Does a Schnorr Signature done with the sum of 2 Elliptic Curve private keys prove possession of the 2 individual keys?
G is the Generator of a Discrete Log Hard Elliptic Curve Group. 2 Private keys x1 & x2, corresponding Public Keys P1 = x1G & P2 = x2G. Now P = P1 + P2 is also a public key with corresponding private key x = x1 + x2. If I …
Private bidding project using MPC
Hello, I have a final project for my bachelor’s degree at university on the topic of private bidding using MPC protocols. However, my coordonative teacher didn’t really provide me with a lot of material or resources in that area and I need a starting point. Could someone give me some …
Diffie-Hellman Key bigger than 64!
Hello, Im currently making a encryption algorithm and I am trying to add a key exchange in my algorithm. I found a method using Diffie Hellman to produce integers however I need a key (datatype) that is bigger than 64!. Because Im shuffling an array of size 64. Im gonna …
