Information security through controlled quantum teleportation networks

Information security is the backbone of current intelligent systems, such as the Internet of Things (IoT), smart grids, and Machine-to-Machine(M2M) communication. The increasing threat of information security requires new models to ensure the safe transmission of information through such systems. Recently, quantum systems have drawn much attention since they are expected to have a significant impact on the research in information security. This paper proposes a quantum teleportation scheme based on controlled multi-users to ensure the secure information transmission among users. Quantum teleportation is an original key element in a variety of quantum information tasks as well as quantum-based technologies, which plays a pivotal role in the current progress of quantum computing and communication. In the proposed scheme, the sender transmits the information to the receiver under the control of a third user or controller. Here, we show that the efficiency of the proposed scheme depends on the properties of the transmission channel and the honesty of the controller. Compared with various teleportation scheme presented recently in the literature, the most important difference in the proposed scheme is the possibility of suspicion about the honesty of the controller and, consequently, taking proper precautions.     

Security and privacy issues of physical objects in the IoT: Challenges and opportunities

In the Internet of Things (IoT), security and privacy issues of physical objects are crucial to the related applications. In order to clarify the complicated security and privacy issues, the life cycle of a physical object is divided into three stages of pre-working, in-working, and post-working. On this basis, a physical object-based security architecture for the IoT is put forward. According to the security architecture, security and privacy requirements and related protecting technologies for physical objects in different working stages are analyzed in detail. Considering the development of IoT technologies, potential security and privacy challenges that IoT objects may face in the pervasive computing environment are summarized. At the same time, possible directions for dealing with these challenges are also pointed out.     

Dependable and reliable cloud-based architectures for vehicular communications: A systematic literature review

Traffic congestion, air pollution, fuel wastage, and car accidents are all exacerbated by increased traffic. Thus, vehicular communications, which refer to information transmission between cars, pedestrians, and infrastructures, have lately gained popularity and been extensively explored due to their enormous potential to enable intelligent transportation and various safety applications. Manually piloted cars and automated vehicles can acquire relevant information via vehicular communications to enhance traffic security and boost entertainment services. The basic concept of automobile clouds was originally published in the literature not long ago, and several suggested structural approaches have been presented in this study thus far. Several academics have concentrated on the structural layout to address various problems and, as a result, satisfy user expectations in order to give dependable services. We examined various vehicular cloud topologies in this study. We also offered a complete summary of current network layer research on allowing efficient vehicle communications and examined specific security, architectural, and reliability concerns in vehicular clouds. Also, the taxonomy of vehicular networks was discussed in terms of the service link between vehicular networks and cloud computing. Ultimately, we discussed the research prospects available.
