Cryptographic system for data applications,in the context of internet of things

With each passing day, Internet of Things (IoT), has the potential to transform our society to a more digital way. In this paper, a cryptographic system is proposed, which has been designed and implemented, following the IoT optimized technologies. As the benefits of IoT are numerous, the need for a privacy platform is more than necessary to be developed. This work aims to demonstrate this by, firstly, implementing efficient and flexible, the fundamentals primitives of cryptography and privacy. Secondly, this is achieved, by introducing applied cryptography, in a more interactive and flexible approach. The proposed system and the incorporation of this platform is scrutinized. In the context of this work, an application of symmetric cryptography is introduced, based on the Advanced Encryption Standard (AES) in Electronic Code Book (ECB), Cipher Block Chaining (CBC) and Counter (CTR) modes of operation, for both encryption and decryption of texts, images and electronic data applications. In addition two other security schemes are supported by the proposed system: AES Galois/Counter Mode (GCM) and AES Galois Message Authentication Code (GMAC). The GCM proposed integration, in an authentication scheme, designed to provide authenticity and confidentiality, at the same time. On the other hand, GMAC, can be applied as message authentication code. Both operations, are optimized in sense of implementation resources, since the major cost is targeted to AES core. In addition, based on the integrated hardware modules, user registration and validation is proposed and implemented, with no additional cost, and with no performance penalty. Furthermore, two factor authentication has been designed and proposed, based on One Time Passwords (OTP), which can been produced with a random procedure. After these, a reference to the security levels, as regards to the communication between the IoT layers of the architecture, is presented. IoT hardware platforms are facing lack of security level and this brings the opportunity to use advanced security mechanisms. Implementation comparison results emphasize the importance of testing and measuring the performance of the alternative encryption algorithms, supported by hardware platforms.     

The Neural Knowledge DNA Based Smart Internet of Things

Abstract

The Internet of Things (IoT) has gained significant attention from industry as well as academia during the past decade. Smartness, however, remains a substantial challenge for IoT applications. Recent advances in networked sensor technologies, computing, and machine learning have made it possible for building new smart IoT applications. In this paper, we propose a novel approach: the Neural Knowledge DNA based Smart Internet of Things that enables IoT to extract knowledge from past experiences, as well as to store, evolve, share, and reuse such knowledge aiming for smart functions. By catching decision events, this approach helps IoT gather its own daily operation experiences, and it uses such experiences for knowledge discovery with the support of machine learning technologies. An initial case study is presented at the end of this paper to demonstrate how this approach can help IoT applications become smart: the proposed approach is applied to fitness wristbands to enable human action recognition.     

Adding sense to the Internet of Things

The Internet of Things (IoT) concept is being widely presented as the next revolution toward massively distributed information, where any real-world object can automatically participate in the Internet and thus be globally discovered and queried. Despite the consensus on the great potential of the concept and the significant progress in a number of enabling technologies, there is a general lack of an integrated vision on how to realize it. This paper examines the technologies that will be fundamental for realizing the IoT and proposes an architecture that integrates them into a single platform. The architecture introduces the use of the Smart Object framework to encapsulate radio-frequency identification (RFID), sensor technologies, embedded object logic, object ad-hoc networking, and Internet-based information infrastructure. We evaluate the architecture against a number of energy-based performance measures, and also show that it outperforms existing industry standards in metrics such as network throughput, delivery ratio, or routing distance. Finally, we demonstrate the feasibility and flexibility of the architecture by detailing an implementation using Wireless Sensor Networks and Web Services, and describe a prototype for the real-time monitoring of goods flowing through a supply chain.     

IoTs (Internet of Things) and DfPL (Device-free Passive Localisation) in a disaster management scenario

This paper presents an overview of the potential obstacles and challenges related to research topics such as IoT, DfPL WSNs (Wireless Sensor Networks) in IoT and disaster management using WSNs. This review will analyse key aspects of deploying a DfPL WSN in IoT scenario for disaster management.In an IoT scenario the DfPL WSN is only collecting raw data that is forwarded to the Internet using a Compressed Sensing (CS) IoT framework or other solutions including data compression. Compressed Sensing (CS) refers to a method used to reduce the number of samples collected in an IoT WSN. Thus it is possible to create stand-alone applications that require fewer resources. There is no need to process the data in the WSN as this can be done in the Data Analysis Network, after the data is reconstructed. This will enable a reduced volume of data transmitted and lower power consumption for battery-operated nodes.The detection of people in a disaster scenario who are simply moving and not in the possession of a ‘tracking device’ is revolutionary. The aim here is to build upon our patent-pended technology in order to deliver a robust field-trial ready human detection system for disaster situations.

This paper presents a comprehensive review of emerging technologies for the internet of things (IoT)-based smart agriculture. We begin by summarizing the existing surveys and describing emergent technologies for the agricultural IoT, such as unmanned aerial vehicles, wireless technologies, open-source IoT platforms, software defined networking (SDN), network function virtualization (NFV) technologies, cloud/fog computing, and middleware platforms. We also provide a classification of IoT applications for smart agriculture into seven categories: including smart monitoring, smart water management, agrochemicals applications, disease management, smart harvesting, supply chain management, and smart agricultural practices. Moreover, we provide a taxonomy and a side-by-side comparison of the state-of-the-art methods toward supply chain management based on the blockchain technology for agricultural IoTs. Furthermore, we present real projects that use most of the aforementioned technologies, which demonstrate their great performance in the field of smart agriculture. Finally, we highlight open research challenges and discuss possible future research directions for agricultural IoTs.
