Data Encryption Methods
Encryption plays a crucial role in protecting sensitive outsourcing data, ensuring it’s accessible only to those with proper authorization.
How End-to-End Encryption Works
End-to-end encryption (E2EE) keeps data encrypted from the moment it’s sent until it reaches the intended recipient. Only the recipient with the correct decryption key can unlock the information. Here’s how it works:
- Generate unique public-private key pairs.
- Encrypt the message using the recipient’s public key.
- Send the encrypted data.
- Decrypt the message using the recipient’s private key.
This method ensures that even if the data is intercepted, it remains unreadable without the private key.
Protecting Data at Rest and in Transit
Data requires different encryption methods depending on whether it’s stored or being transmitted. Here’s a breakdown:
| Data State | Encryption Method | Protection Level | Implementation |
|---|---|---|---|
| At Rest | File-level Encryption | High | Individual files or folders |
| At Rest | Full-disk Encryption | Very High | Entire storage devices |
| In Transit | TLS/SSL | High | Network communications |
| In Transit | VPN Tunneling | Very High | Secure network overlay |
These methods ensure that both stored and moving data are shielded from unauthorized access.
Current Encryption Standards
Several encryption standards are widely used to secure data:
- AES-256: A symmetric encryption standard ideal for securing stored data.
- RSA-4096: An asymmetric encryption method used for digital signatures and secure data transmission.
- TLS 1.3: Protects data in transit with advanced features like perfect forward secrecy.
Here’s a quick comparison of these standards:
| Protocol | Key Length | Security Level | Best Use Case |
|---|---|---|---|
| AES-256 | 256-bit | Very High | File encryption |
