Certificate details

Certificate ID #19
Status historical
Historical reason Validation Sunsetting Policy - FIPS 140-1 Certificate
Validation dates 29.06.1998
Standard FIPS 140-1
Security level 2
Type Hardware
Embodiment Multi-Chip Stand Alone
Caveat When using vendor-initialized SHA-1 in transaction group 1)(Note: This validation has been superseded by validation certificate #41, which meets an Overall Level 3
Exceptions
  • Physical Security: Level 3 +EFP
  • EMI/EMC: Level 3
Description Provides hardware cryptographic services (e.g., secure private key storage, high-speed math accelerator for 1024-bit public key crypto, hashing). Services are provided using a single silicon chip packaged in a 16mm stainless steel case. Can be worn or attached to an object for info at point of use. Can withstand harsh outdoor environments and is durable for everyday wear.

Automated analysis

Automated inference - use with caution

All attributes shown in this section (e.g., links between certificates, products, vendors, and known CVEs) are generated by automated heuristics and have not been reviewed by humans. These methods can produce false positives or false negatives and should not be treated as definitive without independent verification. This applies equally to the Cross-references section below. If you want to know more about how this data is computed and how reliable it is, see our documentation on automated analysis. If you believe any information here is inaccurate or harmful, please submit feedback.

No automatically derived data are available in this section.
