The receiving station, such as an access point performs decryption upon receiving the frame. The network card encrypts the data before transmission using an RC4 stream cipher provided by RSA Security. WEP is defined in the 802.11b standard and aims to provide security by encrypting data over radio waves so that it is protected as it is transmitted from one end point to another. WEP works by using secret keys, or codes to encrypt data. I would suggest WEP as a selection of last resort as it’s still better than keeping the wireless network wide open without security.WEP (Wired Equivalent Privacy) was originally intended to give you the same or similar level of security as on a wired network but it turns out that it does not. The third option is to go with WPA and relatively low quality encryption and authentication. But if you have an old device which does not support WPA2, then you should go with WPA with high encryption and authentication. My final verdict is that if you have a modern device, you should almost always use WPA2 and good encryption and authentication algorithms as this will make your wireless network more secure. Here’s the comparison table for you to easily check the differences between WEP, WPA and WPA2 Protocol Encryption Authentication WEP RC4 PSK 64-bit WPA RC4 and TKIP PSK 128 & 256 bit WPA2 AES-CCMP AES-PSK 256 bit Conclusion
You may check out the following video which explains about an experiment of comparing speed and performance of these three protocols, WEP, WPA and WPA2. This is because it allows more bandwidth to be transferred between the Wireless Access Point and wireless device. Instead of using more encryption and security, WPA2 seems to be the highest performing security protocol of all. But this is totally different from the factual figures. The first thought over speed and performance is that since WEP uses simple authentication and security, it should be the fastest.
But since the users tend to have difficulty setting such a long passwords, the passphrase can be between 8 and 65 characters which is combined with EAP for encryption and authentication. WPA and WPA2 use 256-bit encryption for authentication which is quite secure. The standard which WPA and WPA2 follow for authentication is 802.1x/EAP. While WEP uses simple PSK key, WPA and WPA2 combine it with other encryption methods like WPA-PSK and EAP-PSK to make the authentication process more secure. All three security protocols, WEP, WPA and WPA2 use PSK (Pre-shared Key) for authentication. It determines whether a user is allowed to communicate with the network or not. AuthenticationĪuthentication is an important part of wireless network communication. While WPA2 is the best form of security, you may use WPA where devices are not compatible with WPA2 and use WEP as a last resort as it is still better than the network being completely open. All communication packets sent and received through WPA2 are encrypted. It uses AES-CCMP encryption which theoretically may take hundreds of years for cracking. WPA2 was designed for network communication with complete security in mind. Although it is also weaker form of security but it’s far better than WEP. The secure form of WPA uses TKIP encryption which encrypts passwords for network communication. WPA was developed as a temporary alternative to WEP.
WEP VS WPA SECURITY CRACK
Since WEP sends passwords in plain text across the network, it is quite simple to crack the network using network packet sniffers. RC4 is inherently insecure especially in case of WEP which uses small keys and key management. WEP and WPA use RC4 algorithm for encryption of network data. The factors include security, authentication and performance. Instead of discussing about each security protocol, we will discuss about three factors and compare the protocols according to these factors. WEP vs WPA vs WPA2 Personal vs WPA2 Enterprise That is why it’s important to select the best security protocol which will minimize the risk of being hacked or data leakage. One thing to keep in mind is that the wireless technology is inherently insecure as we can’t control the spread of wireless signals in the air. This article is exactly about knowing which protocol to use at which time. It’s up to the user to select a suitable protocol. Each of these protocols has their own advantages and disadvantages.
