3.2.1.1 Certificates

Your ZyXEL Device can use certificates (also called digital IDs) for user authentication. Certificates are based on public-private key pairs. A certificate contains the certificate owners identity and public key. Certificates provide a way to exchange public keys for use in authentication. A Certification Authority (CA) issues certificates and guarantees the identity of each certificate owner. There are commercial certification authorities like CyberTrust or VeriSign and government certification authorities. In public-key encryption and decryption, each host has two keys. One key is public and can be made openly available; the other key is private and must be kept secure. Public-key encryption in general works as follows. 1 Tim wants to send a private message to Jenny. Tim generates a public key pair. What is encrypted with one key can only be decrypted using the other. 2 Tim keeps the private key and makes the public key openly available. 3 Tim uses his private key to encrypt the message and sends it to Jenny. 4 Jenny receives the message and uses Tims public key to decrypt it.
5 Additionally, Jenny uses her own private key to encrypt a message and Tim uses Jennys public key to decrypt the message. The certification authority uses its private key to sign certificates. Anyone can then use the certification authoritys public key to verify the certificates.

3.2.1.2 WEP

3.2.1.2.1 Data Encryption WEP (Wired Equivalent Privacy) encryption scrambles all data packets transmitted between the ZyXEL Device and the AP or other wireless stations to keep network communications private. Both the wireless stations and the access points must use the same WEP key for data encryption and decryption. There are two ways to create WEP keys in your ZyXEL Device. Automatic WEP key generation based on a password phrase called a passphrase. The passphrase is case sensitive. You must use the same passphrase for all WLAN adapters with this feature in the same WLAN. For WLAN adapters without the passphrase feature, you can still take advantage of this feature by writing down the four automatically generated WEP keys from the Security Settings screen of the ZyXEL utility and entering them manually as the WEP keys in the other WLAN adapter(s). Enter the WEP keys manually. Your ZyXEL Device allows you to configure up to four 64-bit, 128-bit or 256-bit WEP keys. Only one key is used as the default key at any one time. 3.2.1.2.2 Authentication Type The IEEE 802.11b/g standard describes a simple authentication method between the wireless stations and AP. Three authentication types are defined: Auto, Open System and Shared Key. Open System mode is implemented for ease-of-use and when security is not an issue. The wireless station and the AP or peer computer do not share a secret key (WEP key). Thus the wireless stations can associate with any AP or peer computer and listen to any transmitted data that is not encrypted. Shared Key mode involves a shared secret key (WEP key) to authenticate the wireless station to the AP or peer computer. This requires you to enable the wireless LAN security and use same settings on both the wireless station and the AP or peer computer. Auto authentication mode allows the ZyXEL Device to switch between the open system and shared key modes automatically. Use the auto mode if you do not know the authentication mode of the other wireless stations.

3.2.1.3 IEEE 802.1x

The IEEE 802.1x standard outlines enhanced security methods for both the authentication of wireless stations and encryption key management. Authentication can be done using an external RADIUS server. 3.2.1.3.1 EAP Authentication EAP (Extensible Authentication Protocol) is an authentication protocol that runs on top of the IEEE 802.1x transport mechanism in order to support multiple types of user authentication. By using EAP to interact with an EAP-compatible RADIUS server, an access point helps a wireless station and a RADIUS server perform authentication. The type of authentication you use depends on the RADIUS server and an intermediary AP(s) that supports IEEE 802.1x. The ZyXEL Device supports EAP-TLS, EAP-TTLS and EAPPEAP. Refer to the Wireless Security appendix for descriptions. For EAP-TLS authentication type, you must first have a wired connection to the network and obtain the certificate(s) from a certificate authority (CA). A certificate (also called a digital ID) can be used to authenticate users, and a CA issues certificates and guarantees the identity of each certificate owner.

3.2.1.4 WPA

Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. WPA improves data encryption by using Temporal Key Integrity Protocol (TKIP), Message Integrity Check (MIC) and IEEE 802.1x. WPA and WPA2 use Advanced Encryption Standard (AES) in the Counter mode with Cipher block chaining Message authentication code Protocol (CCMP) to offer stronger encryption than TKIP. Select WEP only when the AP does not support WPA. WEP is less secure than WPA.

3.2.1.5 WPA2

WPA 2 (IEEE 802.11i) is a wireless security standard that defines stronger encryption, authentication and key management than WPA.

CHAPTER 6

Wireless Screens
This chapter discusses how to configure wireless settings and wireless security on your ZyXEL Device.
6.1 Wireless LAN Overview
This section introduces the wireless LAN (WLAN) and some basic scenarios.
6.1.1 BSS (Infrastructure)
A Basic Service Set (BSS), also called an Infrastructure network, exists when all communications between wireless stations or between a wireless station and a wired network client go through one access point (AP). Intra-BSS traffic is traffic between wireless stations in the BSS. When Intra-BSS is enabled, wireless station A and B can access the wired network and communicate with each other. When Intra-BSS is disabled, wireless station A and B can still access the wired network but cannot communicate with each other.
Figure 26 Basic Service set
Chapter 6 Wireless Screens

6.1.2 ESS

An Extended Service Set (ESS) consists of a series of overlapping BSSs, each containing an access point, with each access point connected together by a wired network. This wired connection between APs is called a Distribution System (DS). An ESSID (ESS IDentification) uniquely identifies each ESS. All access points and their associated wireless stations within the same ESS must have the same ESSID in order to communicate.
Figure 27 Extended Service Set

6.2 Wireless LAN Basics

This section describes the wireless LAN network terms.

6.2.1 Channel

A channel is the radio frequency or frequencies used by IEEE 802.11b wireless devices. Channels available depend on your geographical area. You may have a choice of channels (for your region) so you should use a different channel from an adjacent AP (access point) to reduce interference. Interference occurs when radio signals from different access points overlap, causing signal disruption and degrading performance. Adjacent channels partially overlap, however. To avoid interference due to overlap, your AP should be on a channel at least five channels away from a channel that an adjacent AP is using. For example, if your region has 11 channels and an adjacent AP is using channel 1, then you need to select a channel between 6 or 11.

6.2.2 SSID

The SSID (Service Set Identity) is a unique name shared among all wireless devices in a wireless network. Wireless devices must have the same SSID to communicate with each other.

6.2.3 RTS/CTS

A hidden node occurs when two stations are within range of the same access point, but are not within range of each other. The following figure illustrates a hidden node. Both stations are within range of the access point (AP) or wireless gateway, but out of range of each other, so they cannot hear each other; that is they do not know if the channel is currently being used. Therefore, they are considered hidden from each other.

Figure 28 RTS/CTS

When station A sends data to the AP, it might not know that the station B is already using the channel. If these two stations send data at the same time, collisions may occur when both sets of data arrive at the AP at the same time, resulting in a loss of messages for both stations. RTS/CTS is designed to prevent collisions due to hidden nodes. An RTS/CTS defines the biggest size data frame you can send before an RTS (Request To Send)/CTS (Clear to Send) handshake is invoked. When a data frame exceeds the RTS/CTS value you set (between 0 to 2432 bytes), the station that wants to transmit this frame must first send an RTS (Request To Send) message to the AP for permission to send it. The AP then responds with a CTS (Clear to Send) message to all other stations within its range to notify them to defer their transmission. It also reserves and confirms with the requesting station the time frame for the requested transmission. Stations can send frames smaller than the specified RTS/CTS directly to the AP without the RTS (Request To Send)/CTS (Clear to Send) handshake. You should only configure RTS/CTS if the possibility of hidden nodes exists on your network and the cost of resending large frames is more than the extra network overhead involved in the RTS (Request To Send)/CTS (Clear to Send) handshake.
If the RTS/CTS value is greater than the Fragmentation Threshold value (see next), then the RTS (Request To Send)/CTS (Clear to Send) handshake will never occur as data frames will be fragmented before they reach RTS/CTS size. Note: Enabling the RTS Threshold causes redundant network overhead that could negatively affect the throughput performance instead of providing a remedy.
