29000142-001 A 5
The following cryptographic modules have been implemented in the
3e-528 .
• AES (128/192/256 bit)
• 3DES (192 bit)
• WEP
• WPA
• 802.1x/EAP-TLS for authentication
Wireless Basics
Wireless networking uses electromagnetic radio frequency waves to
transmit and receive data. Communication occurs by establishing radio
links between the wireless access point and devices congured to be part
of the WLAN.
The 3e-528 incorporates WiFi standard and FIPS 140-2 security for
wireless communication.
802.11b
The IEEE 802.11b standard, developed by the Wireless Ethernet
Compatibility Alliance (WECA) and ratied by IEEE, establishes a stable
standard for compatibility. A user with an 802.11b product can use any
brand of access point with any other brand of client hardware that is built
to the 802.11b standard for basic interconnection. 802.11b devices provide
11 Mbps transmission (with a fallback to 5.5, 2 and 1 Mbps depending on
signal strength) in the 2.4 GHz band.
For wireless devices to communicate with the 3e-528 , they must meet
the following conditions:
• The wireless device and wireless access point must have
been congured to recognize each other using the SSID (a
unique ID assigned in setup so that the wireless device is
seen to be part of the network by the 3e-528 );
• Encryption and authentication capabilities and types en-
abled must conform; and
• If MAC ltering is used, the 3e-528 must be congured to
allow the wireless device’s MAC address to associate (com-
municate) with the 3e-528 wireless interface.
802.11g
Because 802.11g is backwards-compatible with 802.11b, it is a popular
component in LAN construction. 802.11g broadens 802.11b’s data rates
to 54 Mbps within the 2.4 GHz band using OFDM (orthogonal frequency
division multiplexing) technology.
