The Internet of Things is integrating information systems, places, users and billions of constrained devices into one global network. This network requires secure and private means of communications. The building blocks of the Internet of Things are devices manufactured by various producers and are designed to fulfil different needs. There would be no common hardware platform that could be applied in every scenario. In such a heterogeneous environment, there is a strong need for the optimization of interoperable security. We present optimized elliptic curve Cryptography algorithms that address the security issues in the heterogeneous IoT networks. We have combined cryptographic algorithms for the NXP/Jennic 5148- and MSP430-based IoT devices and used them to created novel key negotiation protocol. © 2015 by the authors; licensee MDPI, Basel, Switzerland.

We are witnessing the emergence of a new technology paradigm, one which focuses on the large scale integration and simplification of distributed technologies along with their fundamental realignment around the needs of people and society. The new Human Centric Intelligent Society results from these changes is connecting information from many different sources across the physical and virtual worlds, using the power of integration to achieve new insights and to enact change in ways which are quicker and more context aware than ever before. The Human Centric integration will lead to safer, more comfortable and more prosperous societies, but before arriving to this status, we have several challenges for the existing platforms to be migrated and digitalized into a common Cloud Computing ecosystem, and enable the common things with a Web of Things capabilities that can enable new forms of social infrastructure that react to the needs of people in real time. In this work, we present the contributions and extensions to the EENA Public Safety Answering Points standards and data structure (PIDFLO), in order to enable it with the capabilities to be integrated with data coming from personal and wearable sensors (Internet of Things). In details, we have extended PIDF-LO with the support of OMA LwM2M Web Objects, in order to offer a scalable and interoperable integration of the Internet of Things and the European Emergencies Services based on Open Standards. © 2015 IEEE.

Entropy in computer security is associated with the unpredictability of a source of randomness. The random source with high entropy tends to achieve a uniform distribution of random values. Random number generators are one of the most important building blocks of cryptosystems. In constrained devices of the Internet of Things ecosystem, high entropy random number generators are hard to achieve due to hardware limitations. For the purpose of the random number generation in constrained devices, this work proposes a solution based on the least-significant bits concatenation entropy harvesting method. As a potential source of entropy, on-board integrated sensors (i.e., temperature, humidity and two different light sensors) have been analyzed. Additionally, the costs (i.e., time and memory consumption) of the presented approach have been measured. The results obtained from the proposed method with statistical fine tuning achieved a Shannon entropy of around 7.9 bits per byte of data for temperature and humidity sensors. The results showed that sensor-based random number generators are a valuable source of entropy with very small RAM and Flash memory requirements for constrained devices of the Internet of Things. © 2015 by the authors; licensee MDPI, Basel, Switzerland.

The INPUT Project aims at designing a novel infrastructure and paradigm to support Future Internet personal cloud services in a more scalable and sustainable way and with innovative added-value capabilities. The INPUT technologies will enable next-generation cloud applications to go beyond classical service models, and even to replace physical Smart Devices, usually placed in users homes (e.g., set-top-boxes, etc.) or deployed around for monitoring purposes (e.g., sensors), with their virtual images, providing them to users as a Service. Virtual and physical SDs will be made available to users at any time and at any place by means of virtual cloud-powered Personal Networks, which will constitute an underlying service model. These Personal Networks will provide users the perception to be always in their home LAN with their own smart digital (virtual and physical) devices. The INPUT project will overcome current limitations in the cloud service design due to the underlying obsolete network paradigms and technologies, by: using the computing and storage capabilities of network appliances to allow users create private clouds in the network; exploiting the energy consumed in network appliances more efficiently than in traditional cloud computing scenarios; moving cloud services much closer to end-users and smart-devices, thus avoiding useless network infrastructure overloading; The INPUT Project will foster future-proof Internet infrastructures that will be smarter, fully virtualized, power vs. performance optimised, and vertically integrated with cloud computing, with a clear impact on OPEX and CAPEX of Telecoms, of Service Providers, and of end-users. The INPUT project will extend the programmability of network devices to make them able to host cloud service applications, which will cooperate with the ones in users terminals and datacenters to realize the aforementioned cloud services.
