Data Security

Three features of the AirPort Card help to maintain the security of data transmissions.

• The AirPort Card uses direct-sequence spread-spectrum (DSSS) technology that uses a multi-bit spreading code that effectively scrambles the data for any receiver that lacks the corresponding code.
• The AirPort Card software can use a table of authentic network client ID values to verify each client's identity before granting access to the network.
• When communicating with a base station, the AirPort Card software encrypts the data using Wired Equivalent Privacy (WEP) with a 40-bit security key.
