SMT based attacks on non cryptographic PRNGs

Cracking RNG: Linear Congruential Generator

Breaking a buggy Linear Congruential Generator for ALEXCTF 2017.

An informal, security oriented walkthrough of pseudo-random number generators, exploring design, function, and exploitation.

Python implementation of attacks to recover the seed from a truncated LCG

The paper titled "A secure authenticated image encryption scheme based on elliptic curve cryptography" proposes a robust method for securely transmitting images, particularly medical ones, by employing an authenticated encryption. This algorithm integrates the LRNG, SGPG, and ECC to enhance the randomness and security of the encryption process.

Generate Random Numbers Using LCG Method

Cryptography and Security Project solved by @amir-kedis and @g-magdy

This is an application on generating True Random Numbers & Pseudo Random Numbers using the Linear Congruential Algorithm

To Generate 1,00,000 random numbers using LCG.

Accenture had a nice PRNG challenge at the DSE fair at DTU 2017. This is my solution to it.

Pseudo-random number generators in Python

Lab exercises to understand the concepts of True Random Number Generators (TRNG) and Pseudo-Random Number Generators (PRNG).

Stateshaper uses an equation similar to PRNG or LCG and helps tokenize its output. Memorized values can be created and reproduced for uses such as personalization, synthetic data and world building. This results in a significant size reduction, which can often amount to a savings of over 90%.
