Secure wireless LAN device and associated methods
DC CAFCFirst Claim
1. A secure wireless local area network (LAN) device comprising:
- a housing;
a wireless transceiver carried by said housing;
a medium access controller (MAC) carried by said housing; and
a cryptography circuit carried by said housing and connected to said MAC and said wireless transceiver for encrypting both address and data information for transmission by at least adding a plurality of encrypting bits to both the address and the data information, and for decrypting both the address and the data information upon reception.

Abstract
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.
