To assure surfing the wireless network of its encryption is to protect the wireless network security methods. Here to introduce several models of wireless encryption. WEP (Wired Equivalent Privacy) Although the name would seem a safe option for the cable network, but it is not. WEP standard wireless networks has created an early goal is to become the necessary wireless local area network WLAN security layer, but WEP is no doubt very disappointing performance. It is the source of design flaws. Systems using WEP, the wireless network to transmit data is to use a randomly generated key to encrypt the. However, WEP key used to generate these methods were soon found to be predictable, it is to potential intruders, you can easily intercept and crack the keys. Even a moderate technical level of wireless hackers can be in two to three minutes fast break WEP encryption. IEEE802.11 dynamic Wired Equivalent Privacy (WEP) mode is the design of the twentieth century in the late nineties, when the powerful encryption technology as an effective weapon by the United States strict export restrictions. As the fear of strong encryption algorithm is cracked, wireless networking products are forbidden to export. However, after just two years, dynamic Wired Equivalent Privacy mode is found to have serious shortcomings. However, the error nineties the twentieth century should not be in the presence of wireless network security, or IEEE802.11 standard itself, can not wait for the wireless network industry Electric Electronic Engineers modified the standard, so they launched a dynamic Key Integrity Protocol TKIP (dynamic Wired Equivalent Privacy in the patch version). Although WEP has been proven to be outdated and inefficient, but today in many modern wireless access points and Router , It is still supported. Not only that, it is still being used by individuals or companies most encryption methods. If you are using WEP encryption, if you are on your network security very seriously, then? The future as much as possible not to use WEP, because it really is not very secure. WPA-PSK (TKIP) Wireless network security mechanism is used in the original WEP (wired equivalent privacy), but later found to WEP is very safe, 802.11 Organization began to develop new safety standards, which is later 802.11i protocol. However, the development of standards to the final release takes a long time, but consumers will not take into account network security to give up the original wireless devices, so Wi-Fi Alliance standards before launch, the basis of the draft 802.11i , the set called WPA (Wi-FiProctedAccess) security mechanism, which uses TKIP (Temporal Key Integrity Protocol), which uses the encryption algorithm or encryption algorithm used in WEP RC4, so no need to modify the original radio equipment, hardware, WPA problem for WEP: IV is too short, key management is too simple and the message integrity is not effective protection through software upgrades to improve network security. WPA to provide the appearance of a complete authentication mechanism, AP according to the user authentication results to decide whether to allow its access to wireless networks; authentication is successful according to a variety of ways (the number of transmitted packets, the user access network time) to dynamically change the encryption key for each access user. In addition, users of wireless transmission of data packets in the MIC code, to ensure that user data is not changed by other users. As a subset of 802.11i standard, WPA is the core of IEEE802.1x and TKIP (TemporalKeyIntegrityProtocol). WPA taking into account the different users and different application security requirements, such as: business users need high security (enterprise level), or they might disclose trade secrets is very important; and home users tend to only use the network to browse Internet, send and receive E-mail, print and share files, these users are relatively low security requirements.
