WEP wpa / wpa2 wpa-psk / wpa2-psk differences and characteristics
WEP WEP - Wired Equivalent Privacy Encryption, [url=http://switchonsale.com/huawei/Huawei_Osn_550_Microwave_Equipment.html]Huawei Osn 550 Microwave Equipment[/url] WEP security technology originates from RSA data encryption technology called RC4 to meet the users' higher level of network security needs.
WEP is short for Wired Equivalent Privacy. The Wired Equivalent Privacy (WEP) protocol is a method of encrypting wirelessly transmitted data between two devices to prevent unauthorized users from tapping or intruding into the wireless network .
A security protocol for wireless local area networks (WLANs) as defined in the 802.11b standard. WEP is used to provide the same level of security as wired lan. LANs are inherently more secure than WLANs because the physical structure of the LAN protects them and some or all of the network is buried inside the building to prevent unauthorized access. WLAN via radio waves do not have the same physical structure and therefore are vulnerable to attack and interference. The goal of WEP is to provide security by encrypting data in radios, just as end-to-end. The WEP feature uses the rc4 ping algorithm developed by rsa Data Security. If your wireless base station supports MAC filtering, it is recommended that you use this feature with WEP (MAC filtering is much more secure than encryption).
The WPA WPA, known as Wi-Fi [url=http://switchonsale.com/huawei/Huawei_Ip_Espace_U1960_Huawei_Router.html]Huawei Ip Espace U1960 Huawei Router[/url] Protected Access, has WPA and WPA2 standards and is a system that protects Wi-Fi security. Generation of system Wired Equivalent Privacy (WEP) found in several serious weaknesses arising.
WPA implements most of the IEEE 802.11i standard and is a replacement for WEP before 802.11i is complete. WPA design can be used on all wireless network card, but not necessarily used in the first generation of wireless access point. WPA2 is a complete standard, but it can not be used on some old network cards. Both of these provide excellent security capabilities, but there are also two obvious issues: WPA or WPA2 must be started and selected to be useful instead of WEP, but most installation guidelines make WEP a top priority. When using the "personal" mode most likely to be available in your home and small office, the passphrase required must be longer than the six to eight character password you have been teaching to preserve integrity.

Explanation: WPA is A standards-based interoperable WLAN security enhancement solution that greatly enhances the data protection and access control of existing and future wireless LAN systems. WPA is derived from the ongoing IEEE802.11i standard and will be forward compatible. When properly deployed, WPA ensures that WLAN users' data is protected and that only authorized network users have access to the WLAN network. Due to the proven insecurity of WEP, WPA is used to provide users with a temporary solution until the 802.11i protocol is complete. The standard data encryption using TKIP (Temporary Key Integrity Protocol), there are two modes to choose from authentication, one is to use the 802.1x protocol for authentication; one is called the pre-shared key PSK (Pre-Shared Key) mode.
WPA2 WPA2 (WPA Second Edition) is the Wi-Fi Alliance's certification program for products that use IEEE 802.11i security enhancements.
WPA2-certified products have been in the market since September 2004. Currently, most businesses and many new residential Wi-Fi products support WPA2. As of March 2006, WPA2 has become a mandatory standard. WPA2 requires a Chipset with Advanced Encryption Standard (AES) support. WPA2 has two styles: WPA2 Personal Edition and WPA2 Enterprise Edition. WPA2 Enterprise requires a RADIUS (Remote Authentication Dial-In User) server with 802.1X capabilities. SOHO users without a RADIUS server can use WPA2 Personal Edition with random characters with a password length of 20 or more, or hosted [url=http://switchonsale.com/huawei/Huawei_Ar2200_Router_Ss_Dl_V35_Dte_3.html]Huawei Ar2200 Router Ss Dl V35 Dte 3[/url] services such as McAfee Wireless Security or Witopia SecureMyWiFi.
