Security consideration for IP based aeronautical networks

The internet protocol version 6 (IPv6) is the intended network protocol for the future ATN. In order to fully benefit from IP security capabilities it is important to understand the various mechanisms and the environment in which they will operate. This paper discusses the security conditions of aeronautical communication and analyzes the relevant issues in a generic way. More concrete considerations are given in the second part of the paper where threats (in terms of communication security) to the vision of NEWSKY are briefly discussed and IPv6 security service mechanisms are introduced.
