Explain about Wi-Fi Protected Access
WI-FI full form is Wi-Fi Protected Access which has featured a 128-bit “temporary key integrity protocol” that generates a new key dynamically for each data packet (APs). With upgraded firmware, TKIP was created to be utilized with older WEP devices. Researchers did find a security flaw with TKIP, though; it could only encrypt “short” (128 byte) data packets and had issues retrieving the keystream.
This led to the replacement of TKIP in WPA2 with the more secure CCMP (also known as “AES-CCMP”) encryption protocol. Each wireless device utilizes the same 256-bit authentication key under WPA-Personal, which was created for usage in homes and small offices.
How does it perform the access?
For automatic key generation and enterprise-wide authentication, WPA-Enterprise, which was designed for large enterprises, needs a RADIUS authentication server and Wi- Fi that is encrypted. All of your uploads and downloads are converted into scrambled code via encrypted WiFi, rendering them worthless to hackers unless they can decipher the code or possess a decryption key.
There are four encryption technology standards for WiFi that have been adopted: WEP, WPA, WPA2, and WPA3. No matter which standard you choose, a password is required to use an encrypted WiFi connection. Maybe back then Wi-Fi Protected Access provided you with “wired equal privacy.” But since then, WEP-cracking devices’ computer processing speeds and password cracking software have both significantly improved.

Without explicitly breaking the encryption, it is also possible to acquire WEP keys using simple attacks. Use WEP sparingly; it hasn’t been secure in over a decade. Thus, the WI-FI full form is Wi-Fi Protected Access, or WPA for short, was created. Every encryption standard eventually loses its security.
Another issue is that in only a few years, businesses and governments will be deploying actual quantum computers and quantum computer network technology. All of the encryption that we now use, including wireless encryption, will be very quickly and easily cracked by quantum computers.
