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 …
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 …
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!. …
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 …
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 …
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 …
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 …
Hi, Given SHA256 is supposed to be random and well distributed, is it true to say that essentially each output can have an infinite and relatively equal number of collisions generated by infinite inputs. i.e. given in reality we have …
