|Title:||Improving security information gathering with IEEE 802.21 to optimize handover performance|
|Published:||October 30, 2009|
|Abstract:||In mobile networks, authentication is a time-consuming operation that needs to be shortened in order to provide seamless handovers. Furthermore, the time required for negotiating security parameters and obtaining security policies increases the importance of the authentication performance during handovers. Many optimizations have been proposed for different authentication mechanisms in different network layers. However, they fail to provide means to learn in advance security capabilities and policies in candidate networks, and thus do not reduce the chance of connecting to potentially incompatible target networks. In this paper we use the information capabilities provided by IEEE 802.21 and propose an extension to current network selection algorithms that takes into account>security parameters and policies to optimize the handover performance and reduce the negotiation delay.|
