Explanation / Answer
Difference between WEP and WPA mobile security solution as follows -
WEP is a weak security standard, The password it uses can often be cracked in a few minutes with a basic laptop computer and widely available. WEP is an old IEEE 802.11 standard from 1999, which was outdated in 2003 by WPA, or Wi-Fi Protected Access. WPA was a quick alternative to improve security over WEP.
WEP is vunerable to Firesheep. With manual WEP and a single key, any station with the key can decrypt everything on the network. WEP keys can be stolen or 'cracked' easily. Firesheep can be easily extended to work on a WEP network.WEP is the oldest and weakest of wifi encryption. It's the lowest level protection using a single key on the network. It's the easiest to crack.
WPA (wi-fi protected access) and WPA2 are the most recent (though not new). They use scrambled keys and user authentication. Though better, it's still somewhat vulnerable.Hence,WPA prevent man in middle attack than WEP.
WEP (Wired Equivalent Privacy) WPA (Wi-Fi Protected Access) Older equipment that can use. might not be able to use. Required less processing power Required more processing power Not as strong s WPA provide stronger wireless data encryption 64 or 128 bits encryption key 48-bit keys with more combinations. A security protocol for wireless networks introduced in 1999 to provide data confidentiality comparable to a traditional wired network. A security protocol developed by the Wi-Fi Alliance in 2003 for use in securing wireless networks; designed to replace the WEP protocol. Through the use of a security algorithm for IEEE 802.11 wireless networks it works to create a wireless network that is as secure as a wired network. As a temporary solution to WEP's problems, WPA still uses WEP's insecure RC4 stream cipher but provides extra security through TKIP. Wireless security through the use of an encryption key. Wireless security through the use of a password. Open system authentication or shared key authentication Authentication through the use of a 64 digit hexadecimal key or an 8 to 63 character passcode.Related Questions
