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.

Modular cryptographic device providing multi-mode wireless LAN operation features and related methods

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 network interface carried by the first housing, a cryptographic processor carried by the first housing and coupled to the user network interface, and a first connector carried by the first housing and coupled to the cryptographic processor. Furthermore, the communications module may include a second housing, a second connector carried by the second housing and being removably mateable with the first connector of the cryptographic module, and a network communications interface carried by the second housing and coupled to the second connector.

Modular cryptographic device and related methods

A cryptographic device may include a cryptographic module and a communications module coupled thereto. The cryptographic module may include a user network interface and a cryptographic processor coupled thereto. The communications module may include a network communications interface coupled to the cryptographic processor. The cryptographic processor may communicate with the user network interface using a predetermined protocol, and the cryptographic processor may also communicate with the network communications interface using the predetermined protocol.

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, a cryptographic processor carried by the first housing and coupled to the user network interface, and a first connector carried by the first housing and coupled to the cryptographic processor. The communications module may include a second housing, a second connector carried by the second housing and being removably mateable with the first connector of the cryptographic module, and a network communications interface carried by the second housing and coupled to the second connector. The communications module may also include at least one logic device for cooperating with the cryptographic processor to determine a status of the communications module.

Modular cryptographic device providing status determining features and related methods

A secure wireless LAN device includes a housing, a wireless transceiver carried by the housing, a medium access controller (MAC) carried by the housing, and a cryptography circuit carried by the housing and connected to the MAC and the wireless transceiver. The cryptography circuit may encrypt both address and data information for transmission, and decrypt both address and data information upon reception. Accordingly, a higher level of security may be provided. The cryptography circuit may implement an algorithm and use a key to provide a predetermined security level, such as up to Type 1 security, although lower levels may also be implemented. Of course, the secure wireless LAN device may be used with other LAN devices, such as user stations and/or access points, in any of a number of different LAN configurations. The MAC may implement a predetermined wireless LAN MAC protocol. For example, the LAN MAC protocol may be based upon the IEEE 802.11 standard. The device may also include at least one connector carried by the housing for connecting the MAC to at least one of a LAN station and a LAN access point. This connector may be a PCMCIA connector, for example.

Secure wireless LAN device and associated methods

A secure wireless LAN device includes a housing, a wireless transceiver carried by the housing, and a cryptography circuit carried by the housing. The cryptography circuit may operate using cryptography information and may also render unuseable the cryptography information based upon tampering. The cryptography circuit may include at least one volatile memory for storing the cryptography information, and a battery for maintaining the cryptography information in the at least one volatile memory. Accordingly, the cryptography circuit may further include at least one switch operatively connected to the housing for disconnecting the battery from the at least one volatile memory so that the cryptography information therein is lost based upon breach of the housing. The cryptographic information may comprise a cryptography key and/or at least a portion of a cryptography algorithm. This cryptographic information remains relatively secure and is lost upon tampering, such as removing the housing.
