WPA2-Security for Wi-Fi Network

Wi-Fi Protected Access (WPA/WPA2),  is a security technology for Wi-Fi networks. It was developed to overcome the weaknesses of  WEP (Wired Equivalent Privacy), WPA provides strong encryption by use of either of two standard technologies: Temporal Key Integrity Protocol (TKIP) and Advanced Encryption Standard (AES). WPA also includes built-in authentication support.

It was found TKIP has some security holes.WPA2 was developed with strong wireless encryption and does not allow the use of an algorithm called Temporal Key Integrity Protocol (TKIP). Wi-Fi Protected Access 2 (WPA2), based on IEEE 802.11i, is a new wireless security protocol in which only authorised users can access a wireless device.

Security features of WPA2

1.Stronger cryptography (e.g. Advanced Encryption Standard or AES),

2.Stronger authentication control (e.g. Extensible Authentication Protocol or EAP),

3.Key management,

4.replay attack protection, 

5.data integrity.

Wi-Fi Certification for use of WPA2

Wi-Fi certified product has had to use WPA2 since 2006 and is based on the IEEE 802.11i technology standard for data encryption. WPA2 has  Advanced Encryption Standard(AES) for security.Also, WPA2 requires to enter a longer password than WPA requires. WPA2 ,only,should be active in the router as WPA sometimes interfere with WPA2 and WEP make it easier for hackers to break into the network. 
Both versions of Wi-Fi Protected Access (WPA/WPA2) can be implemented in either of two modes: Personal mode and enterprise mode.What is Wi-Fi,Read Here

 

WPA2 in Personal Mode

When enabling the Personal mode—technically called the Pre-shared Key (PSK) method—of WPA or WPA2 security, you create one unique global password. Everyone enters this same password before connecting to the wireless network. This mode is appropriate for most home networks—but not business networks. A unique encryption passphrase* is defined on the wireless router and any other access points (APs). The passphrase must be entered by users when connecting to the Wi-Fi network. This passphrase is saved on the device.What is WI-Fi Security Read Here
