Quantum Security Verification

I am exploring how quantum-security claims can be turned into reproducible and independently verifiable evidence.

My focus is not simply on whether a system uses Post-Quantum Cryptography (PQC), Quantum Key Distribution (QKD), or other quantum-security technologies.

The question I am interested in is:

When someone claims that a system is quantum-safe, what can an independent third party actually verify from the available evidence?

QSP

QSP Public Verification Portal:
https://github.com/mokkunsuzuki-code/qsp

I am building QSP, an open verification project exploring:

• Post-Quantum Cryptography (PQC)
• Cryptographic Agility
• PQC Migration Evidence
• Cross-Implementation Verification
• Independent Re-verification
• Evidence Portability
• Cryptographic Binding
• QKD Evidence Classification
• Software Supply Chain Integrity
• External Timestamp Evidence
• Independent Assessment

Core Principle

Do not trust a quantum-security claim beyond what its evidence can independently demonstrate.

QSP distinguishes between:

Claimed → Evidenced → Verified → Independently Re-verified

and explicitly records states such as:

Not Verified · Pending · Unknown · Out of Scope

The project does not claim that an entire system is quantum-safe merely because PQC or another quantum-security technology has been implemented.

Mission

From Quantum-Security Claims to Verifiable Evidence.

My current work focuses on reproducible evidence chains for post-quantum security, including cryptographic binding, deterministic verification, cross-implementation interoperability, evidence preservation, and independent third-party verification.

I welcome technical review, reproducibility testing, criticism, and independent verification.
