Wi-Fi Protected Access (WPA) and Wi-Fi Protected Access II (WPA2, RSN) are two security protocols and security certification programs developed by the Wi-Fi Alliance to secure wireless computer networks.

The Advanced Encryption Standard (AES), is a specification for the encryption of electronic data established by the U.S. National Institute of Standards and Technology (NIST) in 2001.AES is based on a design principle known as a substitution-permutation network, combination of both substitution and permutation, and is fast in both software and hardware.[
