ข้อกำหนดความปลอดภัยสำหรับโมดูลการเข้ารหัสที่ใช้ในภาครัฐสหรัฐฯ กำหนดระดับความปลอดภัย 4 ระดับ
NIST FIPS 140-2 specifies the security requirements that cryptographic modules must meet for use in U.S. and Canadian government systems, spanning four levels from basic algorithm correctness to tamper-responsive hardware. Smart cards and hardware security modules are validated against it to demonstrate approved algorithms, key management, and physical protection. It is being superseded by FIPS 140-3, which aligns the U.S. scheme with the international ISO/IEC 19790 standard.
