![]() ![]() By forcing nonce reuse in this manner, the encryption protocol can be attacked, e.g., packets can be replayed, decrypted, and/or forged. According to Researchers, We show that an attacker can force these nonce resets by collecting and replaying retransmissions of message 3 of the 4-way handshake. Each time it receives this message, it will reinstall the same encryption key, and thereby reset the incremental transmit packet number (nonce) and receive replay counter used by the encryption protocol. So a client may receive message 3 multiple times. In this case, sometimes Handshaking message may be dropped or lost so Access Point (AP) will retransmit message 3 if it did not receive an appropriate response as acknowledgment. ![]() Later it will be used for Encrypt the user data using a normal Excryption method by an encryption protocol. Once User joined with the WiFi Network, it used to execute the 4 way-handshake to negotiate A Fresh Encryption key and it will be installed receiving message 3 of the 4-way handshake.
