Current public-key cryptography standards like RSA and elliptic curve cryptography will be rendered obsolete by quantum algorithms, exposing long-lived secrets, credentials, and non-human identities. Organizations that delay migration to post-quantum cryptography (PQC) risk having years of sensitive communications and credentials retroactively exposed. This matters most for data with long confidentiality requirements, such as government secrets, financial records, and persistent machine identities. Beginning the migration with credential management is critical because compromised credentials are the most direct path to systemic breaches.","**Immediate actions:**\n- Conduct a cryptographic inventory to identify all systems relying on RSA, ECC, or other quantum-vulnerable public-key algorithms.\n- Prioritize auditing and rotating long-lived credentials and non-human identities (API keys, certificates, service accounts) that are most at risk from harvest-now-decrypt-later attacks.\n- Classify sensitive data by its required confidentiality lifespan to determine urgency of PQC migration.\n\n**Long-term improvements:**\n- Develop and execute a phased migration roadmap to NIST-approved post-quantum cryptographic algorithms (e.g., CRYSTALS-Kyber, CRYSTALS-Dilithium).\n- Implement crypto-agility in system architectures so cryptographic algorithms can be swapped without full system redesigns.\n- Establish a Non-Human Identity (NHI) management program with short-lived, automatically rotated credentials to minimize exposure windows.\n\n**Detection & Monitoring measures:**\n- Deploy continuous monitoring for anomalous data exfiltration patterns that may indicate harvest-now attacks targeting encrypted traffic.\n- Integrate cryptographic algorithm detection into your asset management and vulnerability scanning tooling to flag deprecated cipher usage.\n- Establish a governance process to track regulatory and standards body updates (e.g., NIST PQC standards) and trigger timely remediation cycles.",[12,13,14,15,16,17,18,19,20,21],"NIST SP 800-208 (Post-Quantum Cryptography Migration)","NIST FIPS 203 \u002F FIPS 204 \u002F FIPS 205 (Approved PQC Standards)","NIST CSF 2.0 – Protect (PR.DS): Data Security","NIST SP 800-57 (Key Management Recommendations)","CIS Control 3: Data Protection","CIS Control 5: Account Management (Non-Human Identities)","CIS Control 16: Application Software Security","GDPR Article 32 – Security of Processing (appropriate technical measures)","ITIL Service Management – Continual Improvement (cryptographic standards lifecycle)","NSA CNSA 2.0 Suite (Commercial National Security Algorithm Suite)",{},"published","2026-06-29T12:20:20.129278+00:00","2026-06-29T12:20:20.018+00:00",{"id":7,"url":27,"slug":28,"title":29},"https:\u002F\u002Fthehackernews.com\u002F2026\u002F06\u002Fwhy-post-quantum-cryptography-starts.html","why-post-quantum-cryptography-starts-with-credentials-ce4cc7","Why Post-Quantum Cryptography Starts With Credentials",[31,37,43],{"id":32,"name":33,"slug":34,"description":35,"color":36},"05757c8d-6b93-4194-b35d-7359e7d33b0e","Vulnerability Management","vulnerability-management","Missing scans, no risk prioritization","#fb923c",{"id":38,"name":39,"slug":40,"description":41,"color":42},"1ec88fde-2d0f-4ed8-932a-33f5ccc0fdc7","Access Control","access-control","Excessive privileges, missing MFA, weak auth","#f97316",{"id":44,"name":45,"slug":46,"description":47,"color":48},"c8b843a5-d5a7-41d1-8d3b-cabded09d2ef","Data Protection","data-protection","Unencrypted data, missing DLP, poor classification","#3b82f6",[],[51],{"slug":52,"name":53,"problem":54},"encryption-key-management","Encryption and key management","Stolen data stays unreadable, and the keys stay under your control."]
