IEEE 802.11i MAC

Overview

IEEE 802.11i is a Wireless Local Area Network standard in the IEEE 802.11 set of specifications. It is also labelled as WPA ™ (Wireless Protected Access) and WPA2 ™ by the Wi Fi Alliance . IEEE 802.11 i is designed to overcome the weaknesses of WEP (Wireless Equivalent Privacy), the original security system for IEEE 802.11 netwo rks It upgrades the WEP algorithm s through TKIP Temporal Key Integrity Protocol ) which uses per packet keys and a better MIC (M essage I ntegrity C ode It also introduces a new encryption algorithm based on AES 128 ( Advanced Encryption Standard ) in CCMP CTR with CBC MAC Protocol ) mode , and a new authentication procedure based on the IEEE 802.1X standard, making it possible to authenticate users using a common password (WPA Personal) or a third party server (WPA Enterprise).

Developed and implemented by Co msis t he IP addresses all industrial Wi Fi markets that need data confidentiality and integrity, as well as users authentication . This IP complete s Comsis IPs portfolio (802.11a/b/g/n/i/e/p/ah)

? Secure and field proven technology

The IP with its enhanced security extension will be is dedicated to Robotics and Factory 4.0 . A simple deployment will soon be operational at Comsis ready for demonstration purposes. Contact Comsis to book your demo, remotely or on site.

? Flexible, scalable, and easy to install

Thanks to a Reference User Manual, a Reference design documentation FPGA /microcontroller synthesis and simulation scripts AD RF daughter card and Avnet SoC dev board the IP is easy to install and handle as illustrated hereafter
