TL;DR
NIZKCTF introduces a secure, open-audit Capture the Flag platform utilizing non-interactive zero-knowledge proofs to enhance fairness and security in cybersecurity competitions.
Contribution
It is the first CTF platform to incorporate non-interactive zero-knowledge proofs for security and transparency.
Findings
Enhanced security against unfair advantages
Open-audit capability for transparency
First implementation of NIZK proofs in CTFs
Abstract
Capture the Flag (CTF) competitions are increasingly important for the Brazilian cybersecurity community as education and professional tools. Unfortunately, CTF platforms may suffer from security issues, giving an unfair advantage to competitors. To mitigate this, we propose NIZKCTF, the first open-audit CTF platform based on non-interactive zero-knowledge proofs.
