Which Encryption Protocol Below Is Used In The Wpa2 Standard?

Which encryption protocol below is used in the Wpa2 standard?

WPA is called wi-fi protected Access, WPA2 is wi-fi protected Access II, WPA3 is wi-fi Protected Access. These are the three security systems organized by the wi-fi company to protect the wireless computer system. These are produced due to the response of several weakness points found in the previous system (WEP) wired equivalent privacy.

WPA was firstly developed in 2013. WPA2 is developed in 2014 it is an anticipation of more complexity and security over WPA. WPA3 was announced in January 2018 with upgrading improvements in the security system over WPA and WPA2. Let’s see the detailed explanation of these three security systems and also know how these are works?

What is WPA?

WPA is developed as an intermediate step over WEP because the full standard is available for WPA. WPA firmware is advanced than WEP on NIC. With the advancement of technology, several changes are needed in the wireless system than those required in network cards.

TKIP (Temporal Key Integrity Protocol) has been integrated with WPA. The encryption key used by WPA is 64 bit or 128 bits. The key manually inserts into the wireless network system.

A message integrity check is developed in WPA to protect wireless devices from attackers who change and resend the data. Message integrity check changes the cyclic redundancy check (CRC) in the already WEP standard. The major drawback of WEP is it does not provide strong data for the data packet to be handled. TKIP is stronger than WEP but less strong than WPA2. The flaws discovered in WPA by the researchers are based on weakness in older WEP.

What is WPA 2?

WPA is replaced by WPA2 in 2014 for major security reasons. It is more advanced than WPA for the protection of the wireless security system. WPA2 uses CCMP and AES-based encryption cards. When it is developed it is mandatory for all the new devices for WPA2 certification.

How WPA2 works?

WPA2 replaces the TKIP and RC4 based on two higher and strong encryption modes. These modes are (AES) advanced encryption standard and (CCMP) counter code cipher block chaining message authentication code protocol. WPA2 uses as a backup plan when CCMP cannot be supported by the device.

Three symmetric block cipher are comprised in AES. Encryption and decryption data are placed in these three blocks of 128 bits, 192 bits, and 256-bit keys. The more powerful computer system is used by the AES from Aps and clients.

CCMP:

It protects data in such a way only accessible to an authorized user to obtained data. It uses cipher block chaining message authentication code for the security of message integrity.

WPA2 enables clients to move from one AP to another by using the same wireless network by using pre-authentication. It is the seamless roaming of WPA2.

Flaws in WPA2:

The big security flaw in WPS2 is the (KRACK) key reinstallation attack vulnerability that damages the wireless encryption keys. This (KRACK) vulnerability is present in the encryption key and affects all over the WPA2.

Many industrial analysts admitted that KRACK is the serious flaw of WPA2. Technologists quickly developed new software to avoid this risk before the arrival of the new generation. A dictionary attack is the four-way handshake method of weak passcodes that easily crack too offline. In dictionary attacks type hundreds, thousands, and millions of passwords to the target network. In this way, attackers crack the handshake of WPA2 gained all information when offline. A dictionary attack is less feasible than long passwords which include uppercase and lower case, letters, special characters, and numbers.

What is WPA3?

In 2018 the most recent and secure wireless security standard is certified that is WPA3. It is one of the most secure that experts consider it. WPA3 uses CCMP-128 and AES-128 personally.

The encryption protocol used by the WPA2:

The encryption protocol used by WPA2 is (AES) advanced encryption standard cipher. Along with (AES) it also uses message validity and integrity checking. These strongly in protection for privacy and integrity than RC4 used by WPA. The WPA2 used the informal names “AES” and “AES-CCMP”.
