What is Format Preserving Encryption (FPE)
NIST has outlined SP 800-38G Revision 1 (FF3-1) which has emerged as better alternative to traditional tokenization. FF3-1 is endorsed by NIST as an advanced encryption standard that encrypts field and preserves its orginal format and type.
Advantages of FPE
FPE distinguishes itself through its remarkable flexibility. Unlike tokenization, which requires modifications to the database schema to incorporate tokens, FPE preserves the original data format. This reduces system intricacies and compatibility issues. Whether you’re encrypting data at the field, file, or database level, FPE guarantees a smooth integration without causing disruptions to the system.
Legacy Tokenization entails transferring sensitive data to a distinct repository, inadvertently establishing an additional focal point for cyber attackers. In contrast, FPE encrypts data at its origin, eliminating the necessity for a separate repository and consequently reducing potential security risks.
FPE smoothly integrates with current systems, requiring only minor adjustments. In contrast, tokenization necessitates substantial changes to databases and their associated applications. FPE’s straightforward integration simplifies the move towards a secure environment, resulting in savings of time, expenses, and resources.
Scalability issues associated with managing a large token database are eliminated when using FPE. Conversely, tokenization’s growth entails the expansion of the token repository, which introduces additional risks and expenses. FPE easily adapts to data expansion, guaranteeing minimal maintenance and efficient scalability.
FPE complies with significant security standards such as HIPAA, GDPR and PCI-DSS, providing businesses with a framework for managing sensitive data. Choosing FPE guarantees conformity with regulatory mandates and upholds a strong security stance.
FPE preserves the original data format, eliminating the necessity for extensive modifications to the database schema. The encrypted SSN retain their 9-digit structure and data type, ensuring compatibility with the system. As the company expands, FPE seamlessly handles the increasing data volume without raising scalability issues or requiring extensive maintenance.
