OPEN SCORING MODEL
Transparent by construction.
QSI measures six dimensions on a 0–100 scale, then applies explicit weights, evidence confidence and critical gates. It is an assessment instrument—not certification by NIST, ETSI, ENISA or any public authority.
Overall QSI
QSI = 0.20I + 0.20Eₓ + 0.20M + 0.15Aᵍ + 0.15V + 0.10G
| DIMENSION | WEIGHT | PRIMARY | SECONDARY |
|---|---|---|---|
| Cryptographic Inventory (I) | 20% | P | K |
| Quantum Exposure Control (Eₓ) | 20% | A | P |
| PQC Migration (M) | 20% | E | R |
| Cryptographic Agility (Aᵍ) | 15% | R | E |
| Validation and Assurance (V) | 15% | E | K |
| Governance (G) | 10% | K | R |
PAREK stage scoring
Each stage score is the importance-weighted mean of questions mapped to that primary stage. Secondary mappings are informational and never double-counted.
PAREKₛ = Σ(wᵢ × sᵢ) / Σwᵢ
Evidence and critical gates
The confidence score reports how much of the scored assessment is supported by acceptable evidence. Critical controls can cap maturity claims, ensuring a named PQC algorithm alone never earns full implementation credit.
