The standardized requirements for encrypted storage and transmission of private domain data typically involve several key aspects:

Encryption Standards:

  • Symmetric Encryption: Utilize strong algorithms like AES (Advanced Encryption Standard) with a sufficient key length (e.g., 256-bit).
  • Asymmetric Encryption: Use protocols such as RSA or ECC (Elliptic Curve Cryptography) for key exchange and digital signatures.

Key Management:

  • Implement secure methods for generating, storing, and rotating encryption keys.
  • Ensure that keys are protected with hardware security modules (HSMs) or similar secure environments.

Secure Transmission Protocols:

  • Employ protocols like TLS (Transport Layer Security) version 1.2 or higher for securing data in transit.
  • Use VPNs (Virtual Private Networks) when transmitting data over the internet.

Data Storage Encryption:

  • Encrypt data at rest using encryption features provided by storage systems or through application-level encryption.
  • Ensure that backups and replicas are also encrypted.

Compliance and Auditing:

  • Adhere to relevant data protection regulations (e.g., GDPR, HIPAA) that specify encryption requirements.
  • Implement logging and auditing mechanisms to track access and changes to encrypted data.

Example:
For a company handling sensitive customer information, they might use AES-256 to encrypt data stored in their databases. When transmitting this data between servers or to users, they would use TLS 1.3 to secure the connection. Keys would be managed using an HSM and rotated regularly. Compliance with GDPR would ensure that they have proper consent and rights management for processing this data.

Cloud Service Recommendation:
For implementing these requirements in a cloud environment, services like Tencent Cloud offer robust solutions. For instance, Tencent Cloud's Key Management Service (KMS) provides secure key management, and their CloudHSM allows for hardware-based key storage. Additionally, using Tencent Cloud's Virtual Private Cloud (VPC) with TLS-enabled services ensures secure data transmission.
