Problem summary
What goes wrong in the field
Health data exchange adds cryptographic complexity beyond ordinary API integration. Integrators must handle key exchange, encryption/decryption, secure storage, expiry, integrity and sensitive-log hygiene without breaking clinical workflows.
Specific pains integrators hit
- Encryption key generation and exchange mistakes break HIU fetch silently.
- Incorrect key references or expired keys cause hard-to-diagnose failures.
- Secure key storage on-prem vs cloud is often under-specified.
- Data integrity checks skipped → corrupted or tampered payloads undetected.
- Secure transport misconfiguration (TLS versions, ciphers) fails WASA or prod.
- Sensitive logging leaks PHI/keys into central log stacks.
- Key rotation without dual-read windows causes mass decryption failures.
How ABDMExpert helps
Practical responses — not slogans
- Encryption engine patterns with safe key handling and redacted logging.
- Key lifecycle checklists (issue, store, rotate, revoke) for production.
- Pipeline tests covering encrypt → transfer → decrypt → FHIR parse.
- Alignment with WASA expectations around secrets and transport security.
