Linux Kernel FIPS Object Module (KFOM) Cryptographic Module

Cisco Systems, Inc. - FIPS 140 #4744

activeLevel 1

The Cisco Linux Kernel FIPS Object Module (KFOM) is a firmware hybrid cryptographic library that serves the operating system kernel. It does not implement any security protocols, instead only allowing for Linux kernel applications access to using approved algorithms.

Key facts

Scheme: FIPS 140
Certificate: 4744
Standard: FIPS 140-3
Security level: Level 1
Status: active
