What is the Difference between WEP and WPA
When wireless networks were created, one of the major problems with them was the security of data. Unlike wired networks, the data was easily captured because of its transmission from a radio device in a wireless network. Many measures were taken to stop this. One was WEP or wireless encryption protocol and the other was Wi-Fi protected access. With these technologies, the data is safely transmitted. Both have differences that are given below.
WEP
Wireless encryption protocol was created to securitize the broadcasted data over a wireless LAN. In wired LAN the data is much more secured than wireless LAN or Wi-Fi. Data is sent in packets after encryption but can be decrypted easily. The WEP key is used to encrypt data which need to be changed periodically to meet the weakness of the WEP. Even though new developments were made in this field, the eavesdropper can easily break the key within 2 minutes.
WPA
Wi-Fi protected access is the new development in wireless network security. To use WPA, all the devices on wireless network are enabled for WPA. If not, the network automatically falls back to WPE. In temporal key integrity algorithm is used in WPA. This key uses hash algorithm and rapidly checks itself for eavesdropping. The easiest WPA to be used for personal use in routers at home is the persona WPA, which does not contain any algorithmic key but a simple English 8-63 lettered phrase.
WEP vs WPA
WEP and WPA both have the task to control and check the system security but WEP loses marks because it can be eavesdropped easily. This is the biggest weakness of WEP. But in WPA the encryption key is made with hash algorithm which is not easily breakable and uses TKIP. WEP is the standard protocol in every wireless device even though the WPA protocol is the widely acceptable and liked one. WPA is the enhanced security protocol which WEP is not.
