1.3 Features
Basic Concepts
WPA
Wi-Fi Protected Access (WPA) is a wireless security draft defined by the Wi-Fi Alliance. The IEEE802.11i standard is
compatible with this draft.
RSN
The IEEE802.11i standard defines the concept of Robust Security Network (RSN): and makes many improvements against
various defects of the WEP encryption mechanism. The functions are equal to WPA2 launched by the Wi-Fi Alliance.
TKIP
The Temporal Key Integrity Protocol (TKIP) is an enhancement on WEP security. TKIP provides key mixing, message
integrity check and key mechanism re-generation for each packet, thus eliminating hidden risks of WEP.
AES
Advanced Encryption Standard (AES) is a new encryption standard published by the National Institute of Standards and
Technology (NIST) of the United States. On October 2, 2000, the Rijndael algorithm designed by Joan Daemen and Vincent
Rijmen from Belgium won with its excellent performance and anti-attack capabilities, and became the new-generation
encryption standard AES.
