1. Jan 2012 HIP DEX for Fast Initial Authentication in 802.11 Date: 2012-01-16 Authors: Slide 1 Konstantinos Georgantas, HIIT

2. May 2011 Abstract The growth of 802.11 wireless networks over the last decade has been tremendous. Through Wi-Fi they have penetrated every market all around the world due to their performance as well as cost efficiency However, there is still much work to be done when it comes to mobility handling in such networks. Handovers between same or different wireless architectures should be seamless and not affect any established connections. The aim of this document is to firstly describe the current 802.11 WLAN architectures and then propose solutions that could possibly face the challenge of reducing the time spent during the link setup. This effort is focused on the authentication process and shall be achieved by either modifying and enhancing the existing standard or by introducing the newly formed Host Identity Protocol in its Diet Exchange version. After critically evaluating all the proposed solutions and proposing any new ones the most feasible one shall be considered for implementation and testing. For this purpose a testing setup of a WLAN (in enterprise mode) is described as well in detail. Lastly this report follows and contributes to the IEEE 802.11 TGai task group in the sense that some of the described proposals were presented there and taken into account for further study.
