What happens to your data when it is encrypted?

What happens to your data when it is encrypted?

Data encryption scrambles information into an unreadable format, requiring a decryption key for access. In HIPAA compliant email and PHI security, encryption renders sensitive health data indecipherable without the specific decryption key, ensuring confidentiality during transmission and storage. In healthcare, encryption plays a significant role in securing protected health information (PHI).


Encryption in HIPAA compliant email

HIPAA regulations mandate stringent measures for safeguarding PHI, especially in electronic communications. Email is the primary mode of information exchange in healthcare and requires robust protection. Transport Layer Security (TLS) is the cornerstone encryption method used.

TLS secures data in transit between servers, shielding it from interception. However, while effective during transmission, it doesn't ensure encryption at rest when stored on servers. 


The encryption process:

Imagine encryption as converting a message into a secret code readable only by those possessing the decoding key. Similarly, encryption transforms plaintext into ciphertext using algorithms and keys. Advanced Encryption Standard (AES) represents a widely recommended encryption standard known for its robust security features. AES encryption, available in varying key lengths, ensures data protection.

The encryption process begins with plaintext undergoing a series of mathematical operations based on the encryption algorithm and the key. This results in creating ciphertext, a scrambled representation of the original data. Only those with the corresponding decryption key can reverse this transformation and retrieve the plaintext.


Implementing encryption for HIPAA compliance

Select HIPAA compliant email service providers offering robust encryption features as the first step toward compliance. HIPAA compliant email providers often offer built-in encryption solutions. Equally important is educating healthcare staff on identifying PHI and using encrypted communication for sensitive data. Continuous monitoring and audits ensure adherence to compliance standards and timely threat detection.


Enhancing PHI security beyond encryption

To keep PHI secure, it's important to have multiple layers of protection. This includes access controls, risk assessments, and incident response plans. Healthcare IT and legal professionals can provide guidance on creating tailored security strategies that meet the latest standards.
