4-120 Avaya W ireless AP-4/ 5/6 User’s G uide
• An 802.11a or 802.11b/g AP supports 64-bit, 128-bit, and 152-bit
encryption:
— For 64-bit encryption, an encryption key is 10 hexadecimal
characters (0-9 and A-F) or 5 ASCII characters (see ASCII
Character Chart).
— For 128-bit encryption, an encryption key is 26 hexadecimal
characters or 13 ASCII characters.
— For 152-bit encryption, an encryption key is 32 hexadecimal
characters or 16 ASCII characters.
NOTE:
64-bit encryption is sometimes referred to as 40-bit encryption;
128-bit encryption is sometimes referred to as 104-bit encryption.
802.1x Authentication
IEEE 802.1x is a standard that provides a means to authenticate and
authorize network devices attached to a LAN port. A port in the context of
IEEE 802.1x is a point of attachment to the LAN, either a physical
Ethernet connection or a wireless link to an Access Point. 802.1x requires
a RADIUS server and uses the Extensible Authentication Protocol (EAP)
as a standards-based authentication framework, and supports automatic
key distribution for enhanced security. The EAP-based authentication
framework can easily be upgraded to keep pace with future EAP types.
