ViotSOC: Controlling Access to Dynamically Virtualized IoT Services using Service Object Capability

Virtualization of Internet of Things(IoT) is a concept of dynamically building customized high-level IoT services which rely on the real time data streams from low-level physical IoT sensors. Security in IoT virtualization is challenging, because with the growing number of available (building block) services, the number of personalizable virtual services grows exponentially. This paper proposes Service Object Capability(SOC) ticket system, a decentralized access control mechanism between servers and clients to effi- ciently authenticate and authorize each other without using public key cryptography. SOC supports decentralized partial delegation of capabilities specified in each server/- client ticket. Unlike PKI certificates, SOC’s authentication time and handshake packet overhead stays constant regardless of each capability’s delegation hop distance from the root delegator. The paper compares SOC’s security bene- fits with Kerberos and the experimental results show SOC’s authentication incurs significantly less time packet overhead compared against those from other mechanisms based on RSA-PKI and ECC-PKI algorithms. SOC is as secure as, and more efficient and suitable for IoT environments, than existing PKIs and Kerberos

Enabling virtual radio functions on software defined radio for future wireless networks

Today's wired networks have become highly flexible, thanks to the fact that an increasing number of functionalities are realized by software rather than dedicated hardware. This trend is still in its early stages for wireless networks, but it has the potential to improve the network's flexibility and resource utilization regarding both the abundant computational resources and the scarce radio spectrum resources. In this work we provide an overview of the enabling technologies for network reconfiguration, such as Network Function Virtualization, Software Defined Networking, and Software Defined Radio. We review frequently used terminology such as softwarization, virtualization, and orchestration, and how these concepts apply to wireless networks. We introduce the concept of Virtual Radio Function, and illustrate how softwarized/virtualized radio functions can be placed and initialized at runtime, allowing radio access technologies and spectrum allocation schemes to be formed dynamically. Finally we focus on embedded Software-Defined Radio as an end device, and illustrate how to realize the placement, initialization and configuration of virtual radio functions on such kind of devices

Yacht Single Window: A case for a vessel-to-infrastructure interaction platform

open8noOne of the most important and promising application of the IoT technologies is in the interaction of "mobile" entities, like cars and trucks, with "static" infrastructures in which they are immersed and from which they depend, like motorways, parking sites, city facilities. This type of application is generally named "vehicle-to-infrastructure" communication. This paper describes the research outcomes of the Yacht Single Window (YSW) project that applied this paradigm to a new and different use case for the IoT: enabling the 'vessel-to-infrastructure' communication in order to exploit the IoT technologies for the benefits of the leisure boats and yachts security, safety and improved connection.openBaglietto, Pierpaolo; Camera, Giancarlo; Maresca, Massimo; Gelli, Stefano; Parodi, Andrea; Serratore, Matteo; Roncarolo, Leonardo; Stasi, NicolaBaglietto, Pierpaolo; Camera, Giancarlo; Maresca, Massimo; Gelli, Stefano; Parodi, Andrea; Serratore, Matteo; Roncarolo, Leonardo; Stasi, Nicol
