What are the requirements of national encryption compliance for enterprise data storage?

National encryption compliance requirements for enterprise data storage typically mandate the use of standardized cryptographic algorithms to protect sensitive data at rest. These requirements ensure data confidentiality, integrity, and availability while aligning with local laws and regulations.

Key Requirements:

1. Algorithm Standards: Use approved encryption algorithms (e.g., AES-256, RSA-2048) to secure stored data.
2. Key Management: Implement secure key generation, storage, rotation, and access controls. Keys must be protected from unauthorized access.
3. Data Classification: Identify and classify data based on sensitivity (e.g., personal, financial, or health data) to apply appropriate encryption levels.
4. Access Controls: Restrict access to encrypted data and cryptographic keys to authorized personnel only.
5. Audit and Monitoring: Maintain logs of encryption-related activities for compliance audits.

Example: A financial institution storing customer payment records must encrypt the data using AES-256 and manage keys in a hardware security module (HSM) compliant with national standards like FIPS 140-2 or China's GM/T series.

For cloud-based storage, Tencent Cloud offers services like Cloud HSM for secure key management and COS (Cloud Object Storage) with built-in encryption to meet compliance needs. These services support industry-standard algorithms and provide audit logs for regulatory reporting.
