User module (12) access capabilities are provided within a wireless Local Area Network (LAN) having distinct user groups (1-3). In this effort, a password is entered into a UM (12) seeking access within a user group (1-3). In response to the password, the UM (12) selects a key and a polynomial from memory (20). Thereafter, packets received by and transmitted from the UM (12) are encrypted, by encryption circuit (52), with the selected key and polynomial. Communictions is permitted if the UM selected key and polynomial are identical to those used by the user group CMs (10). Alternatively, the key is generated as a function of the password, while a polynomial is selected from memory (20).
