What is WPA

English abbreviation: WPA (Wi-Fi Protected Access)

Wi-Fi network security access

Category: Mobile and wireless

Explanation: WPA is a standards-based, interoperable WLAN security enhancement solution that greatly enhances the level of data protection and access control for existing and future wireless LAN systems. WPA is derived from the ieee802.11i standard being developed and will be maintained forward compatible. When deployed properly, WPA guarantees that data for WLAN users is protected and that only authorized network users can access the WLAN network.

Wi-Fi Protected Access (WPA) is a protocol and algorithm for improving the security of the keys used by WEP. It changes the way the key is generated and transforms the key more frequently to get security. It also increases the message Integrity check feature to prevent packet forgery. (Computer science)

The function of WPA is to replace the existing WEP (Wired equivalent Privacy) protocol.
Wireless LANs used to be less secure because of the drawbacks of the standard encryption technology "WEP".
WPA is a new technology that inherits the fundamentals of WEP and addresses the drawbacks of WEP. Because of the enhanced algorithm for generating cryptographic keys, it is almost impossible to compute a common key even when grouping information is collected and parsed.
WPA also adds functionality and authentication features that prevent data from being tampered with halfway through. Thanks to these features, WEP's previously criticized shortcomings have been fully resolved.
