NIST PQ-signature onramp: round 2 candidates announcement
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 …
Cryptopals Set 1 Challenge 6
I'm doing Set 1 Challenge 6 from Cryptopals. This is my code so far: # https://cryptopals.com/sets/1/challenges/6 import base64 with open('repeating-keyXOR.txt', 'r') as file: text = file.read() decoded_bytes = base64.b64decode(text) bits = ''.join(f'{byte:08b}' for byte in decoded_bytes) # let's try keysize from 2 to 40 keysize_list = range(2, 41) def hamming_distance(bytes1, …
Safe to store public key encrypted private key?
I am implementing an anonymous credential system following Lysyanskaya, 2002, specifically much of chapter 3. We assume that the user (not anonymous) U has a user public key PK^(U) (I will try to do my best without LaTeX support here re: notation) and user private key, SK^(U.) When creating the …
The quantum computing revolution nobody is talking about.....
This is probably more significant than any of these papers coming out of China claiming to break RSA or Gift 64 using a western quantum computer. Scott Aaronson, the consummate quantum pessimist has rather abruptly changed his mind. The man who is famous for debunking claims related to quantum capabilities …
Chinese quantum D-Wave news is a repeat from 2023??
How to Read Cryptography Papers?
Does ChatGPT help in understanding cryptography papers? What should I do when I encounter concepts I'm not familiar with when reading papers? What are the most efficient ways to approach research? A lot of topics sound like gibberish, I am also struggling to understand certain mathematical concepts. Any advice?
