Oracle Database is one of the most widely used relational database management systems in the world, known for its robust features, reliability, and high performance. Transparent Data Encryption (TDE) is a specific feature in Oracle Database designed to provide data-at-rest encryption. This guide covers integrating Oracle Database TDE with CryptoHub by using the PKCS #11 standard for enhanced security and performance.

​
Key features

This integration has the following features:
  • Transparent data encryption: Safeguard your sensitive data at rest using industry-standard encryption algorithms, such as AES, without needing to modify your existing applications or database structure.
  • Column-level encryption: Encrypt individual columns within your database tables, protecting only the most sensitive data while maintaining optimal database performance.
  • Tablespace encryption: Secure entire tablespaces with Oracle TDE, providing comprehensive protection for your sensitive data and simplifying encryption management.
  • Data-at-rest encryption: Oracle TDE protects sensitive data stored in database files, ensuring inaccessibility without the proper encryption keys.
  • Seamless operation: TDE operates transparently to the application, meaning you don’t need to modify existing queries or application logic to implement encryption.
  • Key rotation: The feature supports periodic key rotation without requiring data decryption and re-encryption, easing administrative overhead.
  • Integration with Oracle Wallet: You can integrate TDE with Oracle Wallet, a secure key storage mechanism, for additional layers of security.

Benefits of CryptoHub integration through PKCS #11

Integrating with CryptoHub provides the following benefits:
  • Enhanced security: Using a CryptoHub for key storage drastically reduces the possibility of unauthorized key access or compromise, strengthening your database security.
  • Optimized performance: We engineer our HSMs for efficient cryptographic operations, which can improve the performance of encryption and decryption tasks within Oracle Database TDE.
  • Compliance advantage: Integrating with a CryptoHub meets compliance requirements related to secure key management and data protection, such as FIPS 140-2 or GDPR.
  • Operational resilience: The failover and high-availability features of CryptoHub ensure that your Oracle Database remains robust and reliable.
  • Centralized key management: Storing and managing encryption keys in a CryptoHub simplifies key administration, providing a centralized and secure key management solution.
