Course Overview

Addresses the harvest-now-decrypt-later threat model for long-tail insurance liability lines. Covers policyholder data classification by quantum exposure timeline, retention period risk assessment, GDPR and Solvency II obligations, and practical re-encryption strategies for archived policy data spanning 15 to 40+ year retention periods.

Curriculum

Course content is structured into sessions below. Each session is configurable to your organisation's environment, threat model, and objectives.

#	Session	Topics
1	Long-Tail Liability Data and the HNDL Threat Why insurers holding decades of policyholder data face elevated quantum risk	Harvest-now, decrypt-later attack model: adversaries collecting encrypted data today for future quantum decryption Insurance-specific exposure: professional indemnity, medical malpractice, D&O, and environmental liability retention periods of 15 to 40+ years Claims-made versus occurrence policies: how trigger structure determines the cryptographic exposure window Mapping data classes by quantum timeline: policyholder PII, medical records, financial disclosures, legal privilege
2	Policyholder Data Classification by Quantum Exposure Categorising data assets against realistic quantum decryption timelines	Sensitivity tiers: personally identifiable information, protected health information, commercially sensitive disclosures, legal professional privilege Cryptographic shelf life assessment: matching encryption algorithm strength to minimum retention obligations Retention period risk matrix: cross-referencing data class, encryption method, and projected quantum capability milestones Latent claim data: long-tail environmental and industrial disease exposures where data must survive 30+ years
Break
3	Regulatory and Legal Obligations for Long-Duration Data GDPR, Solvency II, and sector-specific requirements intersecting with cryptographic risk	GDPR Article 5(1)(f) and UK GDPR: "appropriate security" obligation evolves as threat landscape changes Data retention versus cryptographic shelf life: when lawful retention creates quantum exposure Solvency II Pillar 2 ORSA: incorporating HNDL risk into Own Risk and Solvency Assessment for long-tail lines PRA SS2/21 operational resilience: archived policy data as an important business service Lloyd's Market Bulletin Y5381: cyber risk governance expectations for data held across syndicate years
4	Interactive Demonstration: Retention Period Risk Assessment Facilitator-led walkthrough of data classification and cryptographic exposure mapping	Building a retention period risk matrix for a sample professional indemnity book Identifying highest-priority re-encryption targets: medical malpractice records with 20+ year retention Calculating the "crypto gap": years between encryption expiry and minimum retention obligation
Break
5	Re-Encryption Strategies for Archived Policy Data Practical approaches to upgrading cryptographic protection on legacy data stores	Re-encryption at rest: batch processing strategies for archived policy documents and claims files Key management for hybrid estates: running classical and post-quantum key hierarchies in parallel FIPS 203 (ML-KEM) for archived data re-encryption: key sizes, performance overhead, and storage implications FIPS 205 (SLH-DSA) for long-retention audit trails: stateless hash-based signatures for 50+ year validity Prioritisation framework: re-encrypt by data sensitivity and retention horizon, not by volume
6	Case Studies: HNDL Risk in Insurance and Adjacent Sectors Lessons from organisations addressing long-duration data quantum exposure	UK Government retrospective classification review: parallels for insurers holding decades of sensitive data Healthcare sector HNDL response: NHS long-term patient record re-encryption planning Common failure patterns: "we will migrate when quantum computers arrive" and the cost of delayed re-encryption
7	Q&A and Action Planning Defining next steps for your organisation
