IEEE 802.11 표준에 포함되어 있는 WEP 방식의 무선 랜 보안이 취약한 것으로 알려진 후 WEP을 대치할 새로운 표준이 802.1li 워킹그룹에 의하여 작성되고 있다. Wi-Fi는 중간단계로서 802.1li의 일부만을 구현하는 WPA 규격을 만들었다. 이 규격은 기존의 하드웨어를 그대로 사용하면서 소프트웨어와 펌웨어 갱신만으로 기존의 무선랜 취약점을 제거할 수 있게 한다. WPA규격을 준수하는 무선 랜 액세스포인트의 개발을 위하여 기존의 액세스포인트 디바이스 드라이버를 WPA를 지원하도록 수정하였으며, 사용자 인증 및 키 교환을 수행하는 소프트웨어를 설계 및 개발하였다.
