An Acronym for Wifi Protected Access
A standard for encryption and authenticating to a wireless AccessPoint.
Can use either RC4 or AES for encryption, and uses RADIUS or a simple password (Pre Shared Key) for authentication.
Under Linux-based operating systems, WPA is handled by a separate program (wpasupplicant) rather than each individual wireless card driver. See WirelessNetworkSecurityNotes for hints on how this works.
