AES AES has been developed to ensure the highest degree of security and authenticity for digital information and it is the most advanced solution defined by IEEE 802 11i for the security in the wireless network Note All devices in the network should use the same encryption method to ensure the communication The WPA PSK key can be from 8 to 64 characters and can be letters or numbers This same key must be used on all of the wireless stations in the network The WEP keys are used to encrypt data transmitted in the wireless network There are two types of key length 64 bit and 128 bit Select the default encryption key from Key 1 to Key 4 by selected the radio button Fill the text box by following the rules below 64 bit Input 10 digit Hex values in the A F a f and 0 9 range or 5 digit ASCII characters including a z 0 9 as the encryption keys For example 0123456 or test1 128 bit Input 26 digit Hex values in the A F a f and 0 9 range or 13 digit ASCII characters including a z and 0 9 as the encryption keys For example 01234567890123456789abcdef or administrator 802 1x Setting Certification CA Server Authentication Type PEAP w Session Resumption Disabled TLS Smart Card Identity TTLS Md5 Challenge Use Client certificate Tunneled Authentication Protocol EAP MSCHAP v2 Identity

30. ture configuration Infrastructure is applicable to enterprise scale for wireless access to central database or wireless application for mobile workers 25 6 Whatis BSS ID A specific Ad hoc LAN is called a Basic Service Set BSS Computers in a BSS must be configured with the same BSS ID 7 Whatis WEP WEP is Wired Equivalent Privacy a data privacy mechanism based on a 40 bit shared key algorithm as described in the IEEE 802 11 standard 8 Whatis TKIP TKIP is a quick fix method to quickly overcome the inherent weaknesses in WEP security especially the reuse of encryption keys TKIP is involved in the IEEE 802 11i WLAN security standard and the specification might be officially released by early 2003 9 Whatis AES AES Advanced Encryption Standard a chip based security has been developed to ensure the highest degree of security and authenticity for digital information wherever and however communicated or stored while making more efficient use of hardware and or software than previous encryption standards It is also included in IEEE 802 11i standard Compare with AES TKIP is a temporary protocol for replacing WEP security until manufacturers implement AES at the hardware level 10 Can Wireless products support printer sharing Wireless products perform the same function as LAN products Therefore Wireless products can work with Netware Windows 2000 or other LAN operating systems to support printer or file sharing
31. y feature the wireless network will be more effective For WLAN security issues this adaptor supports 64 128 bit WEP data encryption that protects your wireless network from eavesdropping It also supports WPA Wi Fi Protected Access feature that combines IEEE 802 1x and TKIP Temporal Key Integrity Protocol technologies Client users are required to authorize before accessing to APs or AP Routers and the data transmitted in the network is encrypted decrypted by a dynamically changed secret key Furthermore this adaptor supports WPA2 function WPA2 provides a stronger encryption mechanism through AES Advanced Encryption Standard which is a requirement for some corporate and government users This adapter is cost effective together with the versatile features it is the best solution for you to build your wireless network 1 1 Features Complies with the IEEE 802 11b and IEEE 802 11g 2 4GHz DSSS standards High data transfer rate up to 54Mbps Supports Turbo Mode to enhance the data transfer speed within the specific wireless network Supports 64 128 bit WEP WPA TKIP with IEEE 802 1x WPA2 AES with IEEE 802 1x functions for high level of security Supports the most popular operating system Windows 98SE Me 2000 XP 2003 Server Supports USB 2 0 1 1 1 0 interface Portable and mini size design 1 2 Specifications Standards IEEE 802 11b g Bus Type USB 2 0 Type A Frequency Band 2 4000 2 4835GHz Industrial Scient
32. y from that point keeping unauthorized users that don t have the matching password from joining the network while encrypting the data traveling between authorized devices WPA2 Like WPA WPA2 supports IEEE 802 1x EAP authentication or PSK technology It also includes a new advanced encryption mechanism using the Advanced Encryption Standard AES AES is required to the corporate user or government users The difference between WPA WPA is that WPA2 provides data encryption via the AES In contrast WPA uses Temporal Key Integrity Protocol TKIP WPA2 PSK WPA2 PSK is also for home and small business The difference between WPA PSK and WPA2 PSK is that WPA2 PSK provides data encryption via the AES In contrast WPA PSK uses Temporal Key Integrity Protocol TKIP When you have set the Authentication Type to Open Shared WPA or WPA2 you can also enable IEEE 802 1x setting to use the authentication server or certification server to authenticate client users Parameter Description Encryption Mode WPA Pre Shared Key WEP Key Key1 Key4 None Disable the encryption mode WEP Enable the WEP Data Encryption When the item is selected you have to continue setting the WEP Encryption keys TKIP TKIP Temporal Key Integrity Protocol changes the temporal key every 10 000 packets a packet is a kind of message transmitted over a network This ensures much greater security than the standard WEP security
