Over the last years the number of AIS messages generated by ships to signal their position has been increasing thus permitting decision support systems to build new strategies based on the elaboration of such data. In this paper we propose an algorithm based on a K-Nearest Neighbor classifier to predict ships routes. The algorithm was tested on real data extracted from AIS messages collected around...
The EU‐funded project UAN (Underwater Acoustic Network) was aimed at conceiving, developing, and testing at sea an innovative and operational concept for integrating underwater and above‐water sensors in a unique communication system to protect offshore and coastline critical infrastructures. This work gives details on the underwater part of the project. It introduces a set of original security features...
A Delay Tolerant Network (DTN) relies on the implicit assumption that nodes cooperate towards message forwarding. However, this assumption cannot be satisfied when there are malicious nodes acting as blackholes and voluntarily attracting and dropping messages.In this paper we propose a reputation-based protocol for contrasting blackholes. Every node locally maintains the reputation of forwarding nodes...
An underwater acoustic scenario raises many problems in terms of security because of the limited bandwidth provided by the underwater medium. In this paper we face with the problem of secure cooperation among underwater acoustic vehicles. We propose a cryptographic suite able to reduce at the minimum the message overhead added by security. The cryptographic suite provides vehicles authentication,...
The UAN - Underwater Acoustic Network - project has among its goals the investigation of networked communication modalities in which mobile nodes are located in the environment in order to optimize the communication characteristics of the acoustic channel. The mobile network nodes in UAN are placed on Autonomous Underwater Vehicles (AUVs) carrying appropriate acoustic modems and capable of autonomous...
An Underwater Acoustic Network (UAN) raises many issues in terms of security. In this paper we focus on attacks performed during the network discovery phase. At the state of art, all underwater discovery protocols do not provide message authenticity so they are exposed to spoofing-based attacks against network integrity and availability. In this paper, we focus on FLOOD [1], a network discovery protocol...
Delay Tolerant Network (DTN) is a network paradigm used to deliver messages when network connectivity is not guaranteed. In a DTN, communication is made possible by carriers, mobile nodes that physically carry messages from a network partition to another. Selecting carriers that provide the best delivery probability is a crucial issue. However, if carriers misbehave, the integrity and availability...
