Many Internet of Things (IoT) applications benefit greatly from low-power long-range connectivity. A promising technology to achieve the low-power and long-range requirements is seen in LoRaWAN, a media access control (MAC) protocol maintained by the LoRa Alliance and leveraging Semtech's patented LoRa radio modulation technology. LoRaWAN provides three different device classes (A, B and C), which...
Internet of Things (IoT) has revolutionized the traditional Internet where only human-centric services were offered. It has enabled objects to have the ability to connect and communicate through the Internet. IoT has several applications such as smart water management systems. However, they require high energy-efficient sensor nodes that are able to communicate across long distance. This motivates...
EtherCAT is one of the real-time Ethernet protocols widely employed in industrial controls. However, its wireless extension is not straightforward due to the unique on-the-fly bus access method based on summation-frame. This paper explores the possibilities of interconnecting EtherCAT with wireless standards such as IEEE 802.11 and 802.15.4. The gateway design is presented and event-driven interconnection...
Secure Multi-party Computation (SMC) has been introduced to allow the computation of generic functions between two parties that want to keep secret the input they use, and share only the computed result. One of the approach proposed to solve the SMC problem relies on the design of Garbled Circuits (GC), that are Boolean circuits that can be evaluated collaboratively achieving the SMC goal. Recently,...
Two-party Secure Multi-party Computation (SMC) is a classical problem in theoretical security. The Garbled Circuit (GC) approach has been proposed as a method for solving SMC using Boolean circuits. Actually, interest has grown in the efficiency of this technique and in its applications to computation outsourcing in untrusted environments. A recent work shows that EXOR gates in a Boolean circuit have...
Industrial Internet of Things covers all aspects of networked intelligent manufacturing systems. This means covering a wide array of application domains and user requirements. In such scenarios it is not feasible to define a single protocol for all situations. Hence, a multi-protocol approach is required. OPC UA has strong backing from Industry 4.0 as the protocol for the Industrial Internet of Things...
LoRaWAN is a Low Power Wide Area Network (LPWAN) technology which enables low cost and low power IoT device communication even in dense urban areas. LoRa modulation is capable of extracting data from a weak signal in noisy environments. This modulation technique can be useful for the delivery of critical data in the noisy environment. In this study, we investigate LoRaWAN technology in the context...
Information-Centric Networking is a promising networking paradigm that overcomes many of the limitations of current networking architectures. Various research efforts investigate solutions for securing ICN. Nevertheless, most of these solutions relax security requirements in favor of network performance. In particular, they weaken end-user privacy and the architecture's tolerance to security breaches...
Dissimilarity between Bluetooth Low Energy based devices limits a number of devices that can be added to a home automation system to a particular brand. This paper presents a new method which enables "brand-free plug-n-play" deployment of smart devices. The method is based on novel approach to home manager concepts of services and properties, and design of adaption mechanism layer. The method...
Rapid innovations in the area of digital things and Information Communication Technology are driving rapid deployment of Internet of Things (IoT) around the globe. Device to Device communications (D2D) in IoT are envisaged through various protocols such as Constrained Access Protocol (CoAP), Message Queue Telemetry Transport (MQTT) and MQTT-SN (for sensor networks). One of the major concerns in the...
In Release 11, the 3rd Generation Partnership Project (3GPP) introduced the ability for Service Capability Servers (SCS) / Machine-to-Machine (M2M) Servers to request that the Mobile Core Network (MCN) deliver a Short Message Service (SMS) device trigger to the User Equipment (UE). The ability to send a trigger avoids the need for the UE to maintain constant contact with the SCS via keep-alive messaging...
The Internet of Things (IoT) paradigm envisions an interconnected world where things can communicate with each other, transmit state information and execute smart tasks. The number of devices connected in Internet has been growing exponentially in the past years and the Machine-to-Machine (M2M) plays a major role in enabling IoT paradigm while it is expected that in the near future billion of devices...
This work introduces the "Packet Too Big"-"Packet Too Small" ICMP based attack against IPsec gateways. We explain how an attacker having eavesdropping and packet injection capabilities, from the insecure network where he only sees encrypted packets, can force a gateway to reduce the Path MTU of an IPsec tunnel to the minimum, which triggers severe issues for the hosts behind this...
Wireless Sensor and Actuator Networks (WSANs) will play an essential role in the future Internet of Things. Wireless communication is an important enabler that provides ease of deployment and reduced installation costs but puts strong constraints on the used communication protocols regarding available bandwidth and reliability. WSANs based on 6LoWPAN allow to use IPv6 within most constrained wireless...
Gateway or cloud based interaction models are widely used for automation solutions that use networked sensors and actuators. In this model, every sensor/actuator interaction goes through the gateway or via the cloud. In order to realize the true Internet of Things philosophy where everything is interconnected, direct interactions between sensors and actuators, also called bindings, are important....
In this paper we propose a 3GPP-compliant distributed paging mechanism over the X2 interface for all-wireless Networks of Small Cells (NoS). An all-wireless NoS is a wireless mesh network that provides multi-hop connectivity amongst small cells, as well as access to functional entities in the mobile operator's core network. The standard 3GPP paging procedure has been designed with traditional macrocell...
Because energy efficiency is gaining more importance these days and Bluetooth Low Energy (BLE) could be used to make use of potential everyday objects into Internet of Things (IOT) — a software, platform and vendor independent common service interface that can be used in such low resource devices has high potential. OPC UA is an emerging middleware solution that addresses the above points but is bulky...
This last few years experienced a new paradigm called Cloud Computing (CC), coming as an extension of Grid Computing and Distributed Computing. This raises many questions about the appropriate infrastructure, processes, and strategy for enacting detection and response to intrusion in a Cloud environment. This article discusses the security and the visibility issues of inter-VM traffic and solutions...
Traditionally, in a typical SOA environment, a B2B gateway is at the edge of an enterprise, and is responsible for performing business document exchanges with other enterprises. In the existing model often used in mature markets, the enterprise needs to incur the cost of hosting and maintaining the gateway. However, the scenario for emerging markets is different, since they are not totally reliant...
Internet of things (IOT) technology increasingly affects backbone network development. Aiming to reduce or weaken such effects on backbone networks from a traffic perspective and attain no discount on functions in a Cobra Net based digital broadcast system, an enhanced IOT gateway and its evaluation system are presented. Based on the prototype evaluation system, experiments demonstrate the IOT gateway...
