| Abstract | This paper presents an approach to establish a new service that offers a group of mobile users in a wireless campus setting the possibility of creating their own virtual secure network “on the fly ” on top of the wireless LAN infrastructure. From an architectural perspective, we seek to benefit from the successful experience of VPNs in wired networks and to apply it to the wireless domain, by implementing and managing a collection of IPSec tunnels on top of an 802.11 wireless infrastructure. System scalability is considered as a primary objective of the designed system and, consequently, two main complementary solutions are implemented. First, the system relies on a mixed topology architecture of mobile nodes that can adapt to different situations by varying from a star centered at the server to a 3-level binary tree rooted at the server. Second, a smart switching protocol is devised to reduce significantly the number of cryptographic operations therefore enhancing the overall performance of the system. |
