Module description
Quoted from the NIST CMVP entry for this certificate.
The E.F. Johnson Co. Subscriber Encryption Module (SEM) is a cryptographic module meeting FIPS 140-2, Level 1 requirements. The SEM provides Subscriber Equipment, such as the E.F. Johnson Co. 5100 series radio with secure and encrypted voice communication. The SEM supports AES OTAR, AES, DES, DSA, and SHA-1 FIPS Approved algorithms. These algorithms are used for data or voice communication and protection of SEM firmware. The SEM can be implemented into any Subscriber Equipment requiring FIPS 140-2 Level 1 security.
