Detailed Compliance Documentation

Document	Description	Target Audience
BSI IT-Grundschutz	Mapping to BSI modules (CON.1, CON.5, OPS.1.1.5)	IT Security Officers
NIS2 Directive	EU 2022/2555 for critical infrastructure	Critical Infrastructure Operators
IT Security Act 2.0	German implementation of EU requirements	Compliance Managers
GDPR Art. 32	Encryption of personal data	Data Protection Officers
KRITIS Regulation	Sector-specific requirements	Critical Infrastructure Operators
Audit Checklist	Audit checkpoints for auditors	Auditors, BSI

NIST Standards

The library implements the final NIST standards for PQ cryptography:

Standard	Algorithm	Usage	Status
FIPS 203¹⁾	ML-KEM	Key encapsulation	Final (2024)
FIPS 204²⁾	ML-DSA	Digital signatures	Final (2024)

These standards are the result of the 8-year NIST Post-Quantum Cryptography Standardization Project.

Regulatory Recommendations

BSI (Germany)

The Federal Office for Information Security recommends:

Migration to PQ cryptography by 2030³⁾
Hybrid solutions for the transition period⁴⁾
Priority for long-lived data (>10 years protection requirement)⁵⁾

ENISA (EU)

The European Agency for Cybersecurity⁶⁾ recommends:

Immediate evaluation of PQ solutions
Crypto agility as a design principle
Inventory of cryptographic assets
