With the widespread use of mobile embedded devices in the Internet of Things, mobile office, and edge computing, security issues are becoming more and more serious. Remote attestation, one of the mobile security solutions, is a process of verifying the identity and integrity status of the remote computing device, through which the challenger determines whether the platform is trusted by discovering an unknown fingerprint. The remote attestation on the mobile terminal faces many security challenges presently because there is a lack of trusted roots, devices are heterogeneous, and hardware resources are strictly limited. To ARM’s mobile platform, we propose a mobile remote attestation scheme based on ARM TrustZone (TZ-MRAS), which uses the highest security authority of TrustZone to implement trusted attestation service. Compared with the existing mobile remote attestation scheme, it has the advantages of wide application, easy deployment, and low cost. To defend against the time-of-check-to-time-of-use (TOC-TOU) attack, we propose a probe-based dynamic integrity measurement model, ProbeIMA, which can dynamically detect unknown fingerprints that generate during kernel and process execution. Finally, according to the characteristics of the improved dynamic measurement model, that is, the ProbeIMA will expand the scale of the measurement dataset, an optimized stored measurement log construction algorithm based on the locality principle (LPSML) is proposed, which has the advantages of shortening the length of the authentication path and improving the verification efficiency of the platform configuration. As a proof of concept, we implemented a prototype for each service and made experimental evaluations. The experimental results show the proposed scheme has higher security and efficiency than some existing schemes.

The Internet Of Things

The Internet of Things (IoT) enables the integration of data from virtual and physical worlds. It involves smart objects that can understand and react to their environment in a variety of industrial, commercial and household settings. As the IoT expands the number of connected devices, there is the potential to allow cyber-attackers into the physical world in which we live, as they seize on security holes in these new systems. New security issues arise through the heterogeneity  of  IoT  applications and devices and their large-scale deployment.

The internet of things is a new paradigm where smart embedded devices are connected to the internet. In this context, wireless sensor networks (WSN) are becoming an important alternative for sensing and actuating critical applications like industrial automation, healthcare, etc. 6LoWPAN provides a means of carrying packet in the form of IPv6 over IEEE 802.15.4 and other networks. It provides end-to-end IPv6, and as such, it is able to provide direct connectivity to a huge variety of networks and to the internet. It uses an adaptation layer for fragmenting and reassembling of the IPv6 packets. Due to its low-cost communication network, it allows IoT connectivity with limited power and throughput. It can be used to overcome the challenges that are faced during the integration of WSN and IP protocols. This chapter briefly discusses IoT followed by an introduction to IPv6 and 6LoWPAN in detail along with architecture that suits IoT, 6LoWPAN mote design features and functions. It also focus on the advantages of LoWPAN with respect to IoT and its security along with smart city case studies.

In recent years, a new generation of the Internet of Things (IoT 2.0) is emerging, based on artificial intelligence, the blockchain technology, machine learning, and the constant consolidation of pre-existing systems and subsystems into larger systems. In this work, we construct and examine a proof-of-concept prototype of such a system of systems, which consists of heterogeneous commercial off-the-shelf components, and utilises diverse communication protocols. We recognise the inherent need for lightweight security in this context, and address it by employing a low-cost state-of-the-art security solution. Our solution is based on a novel hardware and software co-engineering paradigm, utilising well-known software-based cryptographic algorithms, in order to maximise the security potential of the hardware security primitive (a Physical Unclonable Function) that is used as a security anchor. The performance of the proposed security solution is evaluated, proving its suitability even for real-time applications. Additionally, the Dolev-Yao attacker model is considered in order to assess the resilience of our solution towards attacks against the confidentiality, integrity, and availability of the examined system of systems. In this way, it is confirmed that the proposed solution is able to address the emerging security challenges of the oncoming era of systems of systems.

Abstract- Cloud computing is Internet-based computing, whereby shared resources, software and information, are provided to computers and devices on-demand, like the electricity grid. It aims to construct a perfect system with powerful computing capability through a large number of relatively low-cost computing entity, and using the advanced business models like SaaS (Software as a Service), PaaS (Platform as a Service), IaaS (Infrastructure as a Service) to distribute the powerful computing capacity to end users’ hands. Cloud Computing represents a new computing model that poses many demanding security issues at all levels, e.g., network, host, application, and data levels. The variety of the delivery models presents different security challenges depending on the model and consumers’ Quality of Service (QoS) requirements. Confidentiality, Integrity, Availability, Authenticity, and Privacy are essential concerns for both Cloud providers and consumers as well. This paper introduces the existing issues in cloud computing such as security, privacy, reliability and so on. This paper surveys the security problems of current cloud computing.

The participation of Internet devices in different communications through embedded technologies and the adaptive and interactive nature of each communication affects future development tools and applications. The majority of IoT devices are able to communicate over a wireless network, improving their usability and scalability quickly. But these usability improvements drew the attackers' attention to their personal advantages and created numerous security challenges for detection and protection. Because devices are exposed to the Internet to deliver services, they are particularly vulnerable to various threats to security and privacy.Therefore, a major concern on the Internet of Things (IoT) is the discovery of such abnormal activities that pose a security threat so that appropriate solutions can be provided with a high level of reliability. This paper will be based on a detailed overview of IoT wireless security issues and abnormal activity detection methods. It also provided an overview of the various anomaly detection models and security challenges for launching the IoT connection to the wireless network.
