Silk Encryption Module
Silk Encryption Module, from Silk, holds FIPS 140-2 certificate #2689 at overall level 1. The validation is historical: agencies may keep the module in existing systems but not buy it new. Below are its validation history, algorithm certificates and security policy, drawn from the NIST CMVP entry.
Caveat: When operated in FIPS mode. The module makes no assurance of the minimum strength of random strings and generated keys. This validation entry is a non-security relevant modification to Cert. #2038.
