Abstract
A cryptographic device may include a cryptographic module and a communications module removably coupled thereto. The cryptographic module may include a first housing, a user Local Area Network (LAN) interface carried by the first housing, and a cryptographic processor carried by the first housing and coupled to the user LAN interface. The communications module may include a second housing and a network wireless LAN interface carried by the second housing. The network wireless LAN interface may be coupled to the cryptographic processor, and it may be switchable between wireless LAN modes.
