This project is an unofficial implementation of STATISTICAL RANDOM NUMBER GENERATOR ATTACK AGAINST THE KIRCHHOFF-LAW-JOHNSON-NOISE (KLJN) SECURE KEY EXCHANGE PROTOCOL. Not only the four attacks against KLJN scheme were implemented, but also a CTF challenge according to the attack was created. Make fun of it and issue (or PR :D) if there is any mistake.
The four attacks include
- Bilateral attack demonstration utilizing cross-correlations between Alice’s/Bob’s and Eve’s wire voltages, currents and powers
- Bilateral attack demonstration utilizing cross-correlations among the voltage sources
- Unilateral attack demonstration utilizing cross-correlations between Alice’s/Bob’s and Eve’s wire voltages, currents and powers
- Unilateral attack demonstration utilizing cross-correlations among the voltage sources
This Project includes three file as follow:
python3 Implementation.py can output the result under four attacks, and the default ground truth = LH and M = 0.1 .
python3 KLJN_Crack.py will generate a CTF challenge file data.py, with which challenger can solve the challenge by the first attack.
After executing KLJN_Crack.py, python3 sol.py will solve the challenge and output the flag.
By calculating cross-correlation coefficient of Uw, UHH, UHL, ULH, ULL, challenger can utilize the information leak and get the flag.
