Authenticated encryption is provided by 256-bit Galois/Counter Mode Protocol (GCMP-256).WPA3 is built upon WPA2, but it provides a number of improvements:

This mechanism allows to protect the data even if the password is weak, meaning is short or using popular phrases.

This method is based on key exchange and is resistant to offline dictionary attacks, where previously recorded data can be used to guess password. In WPA3-Personal Pre-shared Key (PSK) is no longer in use and Simultaneous Authentication of Equals (SAE) comes in favor. WPA3 comes in two variants WPA3-Personal and WPA3-Enterprise, just like WPA2. The aim of WPA3 is to simplify security, enable robust authentication and increase cryptographic strength. They kept us waiting for some time, but recently new details were revealed. We learned only about few functionalities, without much details. WPA3ДЄt the beginning of the year, Wi-Fi Alliance announced that WPA3 will be introduced in the near feature. Header must be transmitted as plain-text in order to enable frame detection and decoding. Whole message, including header is taken into consideration for integrity check, while only payload is encrypted. Input message is divided into 128 bits parts and used together with a previous results as an input to the AES algorithm. This is a block-based algorithm, operating on 128 bits chunks.

In WPA2 the Counter Mode with Cipher block Chaining Message Authentication Code Protocol (CCMP) uses an Advanced Encryption Standard (AES).Д«oth integrity check and encryption are based on Advanced Encryption Standard (AES) algorithm. The most important architectural change is the data encryption algorithm. It provides a significant security improvement over WEP and WPA. WPA2 implements all mandatory features from 802.11i. If a malicious user is legitimately connected to some network protected with WPA it can capture packets destined for others and decrypt them. It is important to remember, that WPA protects well enough only against those who donвЂ™t have a key. so it is much harder to forge message with correct MIC vector. Algorithm is based not only on the data, but also additional input, such as Transmitter Address, Destination Address, etc. It introduced Message Integrity Check (MIC) algorithm, which by design was better suited to this task than CRC32 used in WEP. Output message is, as in case of WEP, xor operation of the user data and pseudorandom stream from RC4, but this time the key is much better protected and collision is less likely. This makes the main key hard to compromise. Moreover a master key (so a password you enter in access point and station) is not directly used, but rather it is mixed and encryption key is derived from master key. LetвЂ™s see the figure below and investigate what are the differences from previous approach.Д®ncryption was still based on RC4, since it was hardware implementation and couldnвЂ™t be updated, but IV was extended to 48 bits. Since there were two major flaws in WEP, WPA addressed both of them.

It was implemented as part of the 802.11i features and what is important вЂ“ it was based on the same hardware as WEP, so only firmware upgrade was required to improve the security aspect. Since the improvements were urgent and important to introduce, WPA was the answer. It introduced a number of security improvements. IEEE response to the WEP weakness was 802.11i amendment.

It is strongly advised not to use WEP anymore in any circumstances. This makes WEP key easy to be compromised.

IV is appended to the encrypted message and its purpose is to avoid using the same seed for encrypting different messages.ДЄs it turns out within few minutes so many packets can be captured, that IV collision reaches a probability of 50%. This makes the seed either 64 or 128 bits long. WEP key might either have 40 or 104 bits and IV is always 24 bits long. This is a stream encryption algorithm, which uses a pair of WEP key (a password) and an Initialization Vector (IV) as a seed. On the other hand, RC4 is used for encryption. This method is not very reliable in message integrity check. CRC32 intention was to detect errors during transmission. This is where first flaw of WEP shows up. Integrity Check Vector (ICV) is appended to the user data and forwarded to encryption. In WEP, for data integrity 32-bit cyclic redundancy check (CRC32) is used.
