    Cloud computing enables businesses to use computing resources on-demand anywhere in the world without having to build and maintain computing infrastructures in-house. This model involves multiple parties performing diverse operations via the Internet across multiple organisations. Employees and consumers can access resources and services from their own and associated organisations. Despite the success of cloud computing, its security paradigm has one major challenge: how to determine the identity and access rights of users across all the organisations. The user's credential and sensitive information are always stored and maintained by the parent organisation, however, other partner organisations require verification of the user's identity and access rights to allow them to access their services and resources. The biggest difficulty is to communicate the user's identity to their partner organisations without sending their sensitive information. Numerous open standard identity protocols have been introduced in the last two decades. Amongst all, three standard identity protocols Security Assertion Markup Language (SAML), Open Authentication (OAuth), and OpenID Connect (OIDC) are the most established protocols in the cloud computing industry. Therefore, this paper presents a working prototype and critical analysis of these three open standard identity protocols SAML, OAuth and OIDC. It also explores evaluation criteria which are used for this analysis purpose. Finally, it discusses their strengths and limitations, and determines the most suitable open standard identity protocol for all types cloud computing models

    The Internet of Things (IoT) concept is evolving rapidly and influencing newdevelopments in various application domains, such as the Internet of MobileThings (IoMT), Autonomous Internet of Things (A-IoT), Autonomous Systemof Things (ASoT), Internet of Autonomous Things (IoAT), Internetof Things Clouds (IoT-C) and the Internet of Robotic Things (IoRT) etc.that are progressing/advancing by using IoT technology. The IoT influencerepresents new development and deployment challenges in different areassuch as seamless platform integration, context based cognitive network integration,new mobile sensor/actuator network paradigms, things identification(addressing, naming in IoT) and dynamic things discoverability and manyothers. The IoRT represents new convergence challenges and their need to be addressed, in one side the programmability and the communication ofmultiple heterogeneous mobile/autonomous/robotic things for cooperating,their coordination, configuration, exchange of information, security, safetyand protection. Developments in IoT heterogeneous parallel processing/communication and dynamic systems based on parallelism and concurrencyrequire new ideas for integrating the intelligent “devices”, collaborativerobots (COBOTS), into IoT applications. Dynamic maintainability, selfhealing,self-repair of resources, changing resource state, (re-) configurationand context based IoT systems for service implementation and integrationwith IoT network service composition are of paramount importance whennew “cognitive devices” are becoming active participants in IoT applications.This chapter aims to be an overview of the IoRT concept, technologies,architectures and applications and to provide a comprehensive coverage offuture challenges, developments and applications

    Systematic Review on Security and Privacy Requirements in Edge Computing: State of the Art and Future Research Opportunities

    Edge computing is a promising paradigm that enhances the capabilities of cloud computing. In order to continue patronizing the computing services, it is essential to conserve a good atmosphere free from all kinds of security and privacy breaches. The security and privacy issues associated with the edge computing environment have narrowed the overall acceptance of the technology as a reliable paradigm. Many researchers have reviewed security and privacy issues in edge computing, but not all have fully investigated the security and privacy requirements. Security and privacy requirements are the objectives that indicate the capabilities as well as functions a system performs in eliminating certain security and privacy vulnerabilities. The paper aims to substantially review the security and privacy requirements of the edge computing and the various technological methods employed by the techniques used in curbing the threats, with the aim of helping future researchers in identifying research opportunities. This paper investigate the current studies and highlights the following: (1) the classification of security and privacy requirements in edge computing, (2) the state of the art techniques deployed in curbing the security and privacy threats, (3) the trends of technological methods employed by the techniques, (4) the metrics used for evaluating the performance of the techniques, (5) the taxonomy of attacks affecting the edge network, and the corresponding technological trend employed in mitigating the attacks, and, (6) research opportunities for future researchers in the area of edge computing security and privacy
