NIZKCTF: A Non-Interactive Zero-Knowledge Capture the Flag Platform
This addresses security issues in CTF platforms for the Brazilian cybersecurity community, but it appears incremental as it applies an existing cryptographic method to a new domain.
The authors tackled the problem of security vulnerabilities in Capture the Flag (CTF) platforms, which can lead to unfair advantages, by proposing NIZKCTF, the first open-audit CTF platform based on non-interactive zero-knowledge proofs.
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.
