What type of encryption does WPA2-Personal use?

• A. Certificate-based encryption
• B. Pre-shared key (PSK) encryption
• C. Advanced Encryption Standard (AES)
• D. Public Key Infrastructure (PKI)

Answer: (B)

WPA2-Personal employs pre-shared key (PSK) encryption as the primary method for securing wireless networks. In this approach, a shared passphrase is established by the user, which is then used to generate the encryption keys for the communication session. This method allows devices to authenticate and communicate securely without the need for a dedicated server to manage individual user credentials. Using PSK encryption ensures that only those who know the shared passphrase can connect to the network, thus helping to protect against unauthorized access. It provides a relatively simple yet effective means of securing a wireless connection, making it suitable for home networks or small office environments where the administrative overhead of managing individual user identities is unnecessary. While Advanced Encryption Standard (AES) is also a key component of WPA2 since it defines the encryption algorithm used for securing data, PSK refers specifically to the mechanism of key distribution and authentication. Therefore, although AES is often used in conjunction with PSK, it does not exclusively define the encryption type utilized by WPA2-Personal.
