Final answer:
WPA2 encryption is accomplished using the AES security protocol, which uses a secret key to encrypt and decrypt data. The key length can be either 128 bits or 256 bits, providing strong security for wireless network communications.
Step-by-step explanation:
Encryption under WPA2 is accomplished by using a security protocol called AES (Advanced Encryption Standard).
AES is a symmetric encryption algorithm that uses a secret key to encrypt and decrypt data. It operates on blocks of data and is considered secure and widely used for network communication.
The key used in WPA2 encryption can be either 128 bits or 256 bits long, providing a high level of security to protect wireless network communications.
Encryption under WPA2 is accomplished by using the Advanced Encryption Standard (AES), specifically with Counter Mode with Cipher Block Chaining Message Authentication Code Protocol (CCMP). WPA2, which stands for Wi-Fi Protected Access 2, is designed to secure wireless computer networks.
It provides stronger data protection and network access control than its predecessor, WPA, by utilizing stronger encryption methodologies.
