• Abstract: Mobile communication on the Internet sets more security concerns than traditional mobile networks such as GSM.The network infrastructure registration process should give credentials to the user to let him or her being identi .ed by any service provider in order to preven fraudulen use.In addition,a user should be able to communicate with privacy and to sign a message (e.g.a paymen order)so that billing is possible. Users should be able to connect from everywhere,with various ypes of terminals,possibly mobile.In this paper,we propose to secure an infrastructure providing telecommunication services on the Internet for a mobile user.We establish a trust relationship be ween any pair of the parties with a password-based user access.As for user-to-user commu- nication,both signaling and media data can be secured.We illustrate the use of this infrastructure to provide secure IP-Telephony.

A framework for alarm correlation and fault diagnosis

• Authors: M. Guiagoussou, R. Boutaba and G. v. Bochmann
• Reference: [Guia 99a] Networking and Information Systems Journal, Vol. 2, No. 4 (1999), pp. 459-482.
• Abstract: This paper explores the use of structural and co-operation relations between network components for fault management, particularly during the alarm correlation and fault diagnosis phases. Aggregation, connectivity and use-of-service relations are defined as basic units for building more complex relations. Relations' utilisation policies are defined to help during the alarm correlation and fault diagnosis processes. An example of a mobile wireless network is presented to illustrate the benefits of the relation based alarms correlation.
