Normally while setting the security norms for Wi-Fi Router or mobile, we always come across security types/protocols named WEP, WPA or WPA2. Let us know what exactly do these protocols mean.
Compared to the security algorithms used in early 1990’s have undergone many changes and up gradation. The security system came up with the WEP (Wired Equivalent Privacy) protocol and in 1999 WEP was approved as Wi-Fi security standard. It was aimed to offer the same security level as wired networks. But the encryption was so poor that it could be easily cracked using brute force algorithm. Due to these bunch of well-known security issues, the Wi-Fi Alliance in 2004 disused WEP.
To replace WEP a new security protocol was brought in use, that is WPA. WPA stands for Wi-Fi Protected Access. One year before WEP was officially disused, WPA was formally adopted. WPA Enterprise uses an authentication server for keys and certificates generation. WPA comes with different variants like Traditional WPA personal, known as WPA-PSK (for pre-shared key), is designed for home networking and WPA-Enterprise is designed for corporate networks only. Although WPA was developed to replace WEP, yet it failed in providing complete security protection which allowed intruders to crack the password without facing many difficulties. This was the draw back issued with the WPA.
To develop the strongest security protection, improved version of WPA named WPA2 (Wi-Fi Protected Access version 2) was brought into use in 2006. The most important improvement of WPA2 over WPA was the usage of the Advanced Encryption Standard (AES) for encryption, which made intruders highly impossible to crack the password resulting in a secured flow of data over the network. Alike WPA, WPA2 supports different variants. It always recommended to use the WPA2 protocol to set passwords for Wi-Fi routers or mobile phones.
