164.312(a)(2)(iv) Encryption and Decryption (Addressable)
164.312(a)(2)(iv) in HIPAA Security Rule (the HIPAA Security Rule as it currently stands). All HIPAA Security Rule controls held. Open HIPAA Security Rule on the standards site.
The control as we hold it
Encryption and Decryption (Addressable). Implement a mechanism to encrypt and decrypt ePHI. NIST recommends FIPS 140-validated cryptography, encryption at rest for all ePHI stores, and key management aligned to SP 800-57.

What an auditor commonly asks for
General guidance for this control area (domain: Technical), in our words, not a statement of the standard and not binding on an assessor.
- the unique-user and access-control records
- the audit-log configuration and review records
- the integrity and encryption records for ePHI in transit
