Identity authentication systems form the basis of many security mechanisms in many distributed computing environments today. All authentication mechanisms are based on some form of secret sharing coupled with some cryptographic methods. Each implementation is based on a conceptual model for authentication and makes certain assumptions about the network characteristics on which the distributed system is based. This paper presents conceptual models for authentication and their implementations because of their practical importance. The authentication methods are analysed in terms of their diversity, and a framework for interoperability in a heterogeneous environment is proposed.

With the consistent evolution of distributed networks and cloud computing, the communication process of existing Internet architecture are not at par to offer comprehensive security;thereby fails to cater up the dynamic web security demands of online users. This leads to the evolution of Future Internet Architecture (FIA) that claims of enhanced security system. However, a closer look into both existing web security and security of existing FIA projects shows that there are enough security loopholes in both that demands a novel security solution. Therefore, this paper contributes to investigate the effectiveness of existing web security approaches as well as security approaches of FIA in order to explore the open research issues. The finding of the study shows that there is a significant research gap that demands extreme improvement of existing web security in order to fit for secure communication in FIA.

In a local area network (LAN), the availability of all network components is indispensable. To reach this goal it is necessary to secure a LAN against unwanted communication from outside. If there is an unauthorized access which blocks the internal traffic, the security mechanism has to react and must exclude this traffic from the internal network.

Current technology driven world is moving forward with massive implementation of smart objects. These smart objects or Internet of Things (IoT) nodes are involved in sensing of real time critical data from surroundings. Though these IoT nodes are involved in very specific task but their existence is very important for the complete system. Usually, in an IoT architecture, several heterogeneous nodes connect with a nearest gateway. The gateway itself connects with the world via Internet. IoT nodes need to flexible about connectivity as those may need to leave and join any gateway based on context (time, location etc.). To achieve flexibility, IoT components need a trust relationship between each other. In this paper, we have proposed a mechanism for integrating distributed trust management in IoT by using edge computing technology, considering the scalability and heterogeneous capability of IoT devices.

New software-defined open network concepts are proposed in this paper to enable an efficient implementation of front-and backhaul solutions for future 5G mobile networks. Main requirements for 5G front-and backhaul are derived and then related to the open network architecture enabling multiple operators to share the same physical infrastructure. The value of software-defined networking (SDN) is particularly outlined therefore. For the use of SDN in the fronthaul, CPRI over Ethernet (CoE) is proposed as a new transport protocol. In the backhaul, distributed security can be implemented using SDN where direct links are confined inside the access domain, as opposed to the current centralized security solution including also the transport domain. In this way, low latency can be realized e.g. for machine-type communications. As the benefits for fixed-mobile convergence are evident, SDN should be enabled increasingly in the access domain.

The development of electronic voting applications remains an active area of research and this has led to the proposal and implementation of many models based on blockchains. However, most of the proposed models are partially decentralized solutions, in which the blockchain is used as a storage media for votes while the application is written in programming tools such as HTML, CSS, and JavaScript. This makes them vulnerable to attacks such as Denial of Service (DoS) attacks, Single Point of Failure (SPF), and fraudulent record modification. In this paper, we propose a fully decentralized electronic voting application, SEVA, in which we placed the whole application (code and data) in Ethereum to protect the application from vulnerabilities. Additionally, we propose a new consensus algorithm, Proof of Smart Vote (PoSV) for SEVA, as a viable energy-saving alternative to the energy-intensive Proof of Work (PoW). We implemented and evaluated SEVA with PoSV and compared it with a partially decentralized model of the application.

security vulnerabilities have become significant concerns due to growing demand of Internet of Things (IoT) not only for home automation systems, but also for various industrial applications. Central security technologies are vulnerable to single-point failure that could reduce attack handling technology efficiency. distributed security frameworks are used in resource-constrained heterogeneous IoT networks. Conventional security strategies are insufficient to protect the distributed and dynamic existence of IoT networks. Conversely, Software Define Network (SDN) and Blockchain are two emerging techniques expected to solve heterogeneous IoT network security. This analysis work therefore mainly seeks to examine IoT network features, security specifications, and challenges. Thereafter, well-known threats or attacks are analyzed in IoT. SDN and blockchain-based countermeasures are addressed for IoT network security with a case study. Finally, to enhance security and privacy, numerous open issues are discussed.

Critical infrastructures are ubiquitous in the modern world and include electrical power systems, water, gas, and other utilities, as well as trains and transportation systems including airports. This work is concerned with Supervisory Control And Data Acquisition (SCADA) systems that are at the heart of distributed critical infrastructures within airports. Modern airports are highly competitive cost driven operations that offer a range of public and private services. Many airport systems such as car parking and building control systems are SCADA controlled. This is achieved with sensors and controllers monitored over a large, geographically disperse area. To increase efficiency and to achieve cost savings, SCADA systems are now being connected to information technology system networks using TCP/IP. The merging of SCADA systems into the main IT network backbone is presenting new security problems for IT security managers. Historically, proprietary solutions, closed systems, ad-hoc design and implementation, and long system life cycles have led to significant challenges in assessing the true security posture of SCADA systems. To address this, this work seeks how SCADA systems are being integrated into the IT network within a modern airport. From this new standpoint we will be able to identify ways in which SCADA may be vulnerable to malicious attack via the IT network. The results of this work could offer solutions to increase security within airports.

modern home networks constitute a diverse ecosystem of devices and services, whose management is mostly handled by means of specific service or device provider mechanisms, with only a minority of customers possessing the technical skills required to deal with such tasks. This means that, when it comes to security, most users often exclusively rely on endpoint protection mechanisms (such as anti-virus) to handle their basic needs. This is mostly due to a basic assumption that considers the home LAN to be a safe environment, with most threats coming from the outside a premise that underlies most of the research about the subject. However, this perspective predates the widespread adoption of mobile appliances, smart devices and related services, some of which may be abused and/or compromised to spy and exfiltrate sensitive information from their owners. Overall, one cannot consider the home LAN to be a safe environment anymore, as potential vulnerabilities and information leaks may come from within. This paper addresses the initial phase of the development plan for a security appliance for Home LANs, capable of providing seamless protection for the ever-growing ecosystem of devices and services which are common on such networks, while also addressing the specific requirements imposed by multi-tenancy and cohabitation with third-party services. By monitoring and controlling network traffic flows on a per-device basis, we intend to make it possible to characterize typical traffic profiles for each type of device, to detect anomalies and/or information leaking events. Eventually, this capability may be leveraged to provide to control device-to-device communications in order to block unwanted interactions between equipment and external sites. By moving beyond the last mile and into the customers' doorsteps, the proposed solution intends to provide comprehensive and contextual security monitoring on a per-user basis, embedded at the residential gateway or eventually resorti
