Design and development of an embedded aeronautical router with security capabilities

Abstract

International audienceAeronautical communications are growing in complexity: avionic systems are more and more connected together through complex networks inside and outside the aircraft. This increase of connections requires highly secure systems to solve the constraints of such network topologies. In this paper, we present the IP based Secure Next Generation Router (SNG router) we have developed, providing regulation, routing, secure merging of different data sources and preserving of their segregation. During the design process we searched for a set of solutions to minimize the certification, design and development costs and maintain a high level of security. This paper is organized as follow: we first introduce the methodology we applied to the SNG router and its benefits. Then we examine the partition in charge of the security of data exchanged through the router. The paper is finished with the validation of our router?s implementation and with the evaluation of our router?s performances

How can model driven development approaches improve the certification process for UAS?

“…This is why we would like to cite [12] where we have introduced a new model driven methodology for fast prototyping of generic aeronautical systems. We have illustrated this methodology in the development of a new embedded router for future aeronautical communications [13].…”

“…In previous research, based on our model driven design approach, we produced a full compliant secure and safe router for aeronautical communications [13]. This device is able to exchange different types of information between the ground and the aircraft (point-to-point communications) in one or several safe and secure communication tunnels.…”

Realistic Network Traffic Profile Generation: Theory and Practice

“…Previous research conducts us to design new methodologies and tools to generate network data traffic as close as possible to what we can find on Local Area Networks (LAN) and on the Internet. It can be necessary for instance to evaluate performances of new network entities (such as an embedded router (Varet et al, 2012)). In this specific context, we needed to face this router to generated traffic with characteristics as close as possible as the Internet traffic.…”
