“…Additionally, there is usually VL redundancy, which means the data of a VL is sent through two different paths simultaneously, typically using two identical networks. The recipient is in charge of managing the redundant packets, usually applying a First-Valid-Wins [51] policy. From a physical link perspective, the packets are duplicated by the redundancy management block and sent through two redundant interfaces using two message authentication code (MAC) interfaces, generically named as MAC A and MAC B.…”

Aircrafts fully rely in a wide variety of electronic systems: sensors, navigation equipment, representation screens and communication elements. The interconnection of these avionics implies a huge challenge for the aircraft communication networks. Extremely stringent requirements in terms of reliability and predictability have to be provided for a safe operation. There are also important limitations to recreate those networks in a prototype form, due to the costs of the related equipment and the interest of testing different architectures and possible configurations dynamically. Moreover, performance estimation approaches based solely on network calculus provide limits for worst-case scenarios, without generating a detailed feedback under different circumstances and configurations of the network and different data sources. In this context, the present work proposes and develops an evaluation framework for avionics networks in order to support the verification and validation (V&V) procedures of the communication system before applying for certification. The proposed framework implements an event-based simulator in Simulink for Avionics Full-Duplex Switched Ethernet (AFDX), one of the most extended data protocols for avionics. This is evaluated in comparison with network calculus and bibliography performance estimation approaches, demonstrating its accuracy and capabilities.

Abstract-The notion of Integrated Modular Avionics (IMA) refers to inter-connected pieces of avionics equipment supported by a wired technology, with stringent reliability and safety requirements. If the inter-connecting wires are physically secured so that a malicious user cannot access them directly, then this enforces (at least partially) the security of the network. However, substituting the wired network with a wireless network -which in this context is referred to as an Avionics Wireless Network (AWN) -brings a number of new challenges related to assurance, reliability, and security. The AWN thus has to ensure that it provides at least the required security and safety levels offered by the equivalent wired network. Providing a wired-equivalent security for a communication channel requires the setting up of a strong, secure (encrypted) channel between the entities that are connected to the AWN. In this paper, we propose three approaches to establish such a secure channel based on (i) preshared keys, (ii) trusted key distribution, and (iii) key-sharing protocols. For each of these approaches, we present at least two representative protocol variants. These protocols are then implemented as part of a demo AWN and they are then compared based on performance measurements. Most importantly, we have evaluated these protocols based on security and operational requirements that we define in this paper for an AWN.
