Title

Environmental Failure Protection/Testing

Control

The electronic devices and circuitry are designed to operate within a particular range of environmental conditions. Deliberate or accidental excursions outside the specified normal operating ranges of voltage and temperature can cause erratic operation or failure of the electronic devices or circuitry that can compromise the security of the cryptographic module. Reasonable assurance that the security of a cryptographic module cannot be compromised by extreme environmental conditions can be provided by having the module employ environmental failure protection (EFP) features or undergo environmental failure testing (EFT).

For Security Levels 1, 2, and 3, a cryptographic module is not required to employ environmental failure protection (EFP) features or undergo environmental failure testing (EFT). At Security Level 4, a cryptographic module shall either employ environmental failure protection (EFP) features or undergo environmental failure testing (EFT).
