Key management requirements in national encryption compliance typically focus on ensuring the secure generation, storage, distribution, usage, rotation, and destruction of cryptographic keys to protect sensitive data. These requirements are often mandated by government regulations or industry standards to prevent unauthorized access and maintain data confidentiality, integrity, and authenticity.

Key Requirements:

  1. Secure Key Generation

    • Keys must be generated using cryptographically secure random number generators (CSPRNGs) to ensure unpredictability.
    • Example: Using a FIPS 140-2 validated random number generator for key creation.

  2. Key Storage

    • Keys should be stored in secure hardware modules (e.g., HSMs) or encrypted key vaults to prevent unauthorized access.
    • Example: Storing encryption keys in a Tencent Cloud Key Management Service (KMS), which provides hardware-backed security.

  3. Key Access Control

    • Strict access policies must be enforced, ensuring only authorized personnel or systems can access keys.
    • Example: Role-based access control (RBAC) in Tencent Cloud KMS to limit key usage.

  4. Key Rotation & Expiry

    • Keys should be periodically rotated (changed) and have defined expiration dates to reduce the risk of compromise.
    • Example: Automated key rotation in Tencent Cloud KMS to enhance security.

  5. Key Backup & Recovery

    • Secure backup mechanisms must exist to prevent data loss if keys are accidentally deleted.
    • Example: Tencent Cloud KMS supports key backup and recovery with strict audit logging.

  6. Audit & Logging

    • All key management activities (generation, usage, access) must be logged for compliance and monitoring.
    • Example: Tencent Cloud KMS provides detailed audit logs integrated with Cloud Audit (CA) for compliance tracking.

  7. Compliance with Standards

    • Key management must align with national standards (e.g., China’s GM/T series, FIPS 140-2, NIST SP 800-57).
    • Example: Tencent Cloud KMS complies with Chinese cryptographic regulations and international standards.

Recommended Tencent Cloud Service:

  • Tencent Cloud Key Management Service (KMS) – A secure and compliant solution for managing encryption keys, supporting HSM-backed key storage, automatic rotation, and detailed audit logs.
  • Tencent Cloud Cloud HSM – A dedicated hardware security module for high-security key storage and cryptographic operations.

These services help organizations meet national encryption compliance requirements while ensuring data protection.
