Which technology is designed to encrypt data at rest specifically in compliance with FIPS 140-2 standards?

Self-encrypting drives (SEDs) are specifically designed to encrypt data at rest and can operate in compliance with FIPS 140-2 standards. FIPS 140-2 is a U.S. government standard that outlines specific security requirements for cryptographic modules, which means that any technology that claims to comply must meet stringent security criteria.

SEDs provide a hardware-based encryption solution that automatically encrypts data as it is written to the disk and decrypts it as it is read, without requiring the user to perform any additional steps. This built-in encryption is transparent to the user, ensuring that data protection is constant and reliable. Furthermore, SEDs typically utilize robust encryption algorithms and can easily be integrated into systems for compliance with various security standards, including FIPS 140-2.

While the other technologies mentioned play a role in securing cryptographic operations or supporting secure environments, they do not specifically focus on encrypting data at rest in a way that directly aligns with the practical application required for FIPS 140-2 compliance. For instance, Hardware Security Modules (HSMs) and Trusted Platform Modules (TPMs) are used primarily for cryptographic key management and device identity protection, whereas measured boot focuses on system integrity validation during the
