“…The term 'decentralized information systems' defines an interconnected information system technology whereby no single entity is the sole authority (www.computerhope.com/jargon/d/decentral.htm) and decentralization of infrastructure described is externalized across geographical locations/region of the world (Müller et al, 2017). The term 'cloud computing' describes an on-demand availability of networked computer systems resources such as storage (cloud storage) computing power where the people do not need to own the resources and without having to worry about the management of the resources.…”

“…As more organizations migrate to the cloud, the security experts need to work more on security strategies on how to secure the data and applications hosted on the cloud as most businesses that would have wanted to migrate to the cloud are skeptical of the security and integrity of the cloud infrastructure (Müller, Ludwig, & Franczyk, 2017). The German privacy laws make provision for data security applicable to private individuals and not very suitable for reliable protection of business data (Müller et al, 2017). The security in a distributed cloud architecture has become a major challenge in the infrastructure development and design of Distributed cloud architecture.…”

The technological advancement and growth of the cloud computing technologies is changing network service provisioning and operation. Cloud based services represented as XaaS where X refers to service offering such as Platform, Software and Infrastructure as a service, provides flexible on-demand provisioning along with its security concerns that goes with the adoption of the cloud computing. Despite all the advantages of adopting the cloud computing option, the security and privacy of the clients’ data cannot be overlooked. Understanding these security concerns is a fundamental requirement to choosing the cloud solution. This paper focuses on the use of Blockchain technology to mitigate the security challenges of the cloud computing. Literature reviews have discussed other security options for the cloud, but little discussions have centered on the adoption of the Block Chain technology to secure the cloud and open doors for future research of cloud computing using smart contract.

“…While it can be argued that the individual concepts of benefits realisation, requirements and FED have been developing over the years, what the results indicate is that they have been doing so independently and individually with limited linkage. As a highlight, for example, the plethora of research into requirements management [43,48,49]; has been limited in its explicit adoption of benefits realisation principles [40]. Studies such as ul Musawir, Serra [40] point to potential benefits in project governance and stakeholder management two of an important array of requirements for project success.…”

Front End Projects Benefits Realisation from a Requirements Management Perspective—A Systematic Literature Review

The recent notable emergence of a body of research in requirements management on one hand and benefits realisation has contributed to addressing a growing need for improved performance in Architecture, Engineering and Construction (AEC) projects. However, front end design (FED) as one of the vital processes in the project life cycle and delivery has attracted limited research to date within this understanding. This paper aims to map current evidence on requirements management in facilitating benefits realisation from an FED perspective. This is to bring about an updated and unified position on requirements management for its impact on design decision making. A systematic review of the literature covering the last ten years (2008–2018) aims first to build understanding and support identification of these emergent conceptual positions and secondly underscore essential requirements and their categorisations that impact on design discourse in FED. One hundred sixty-one peer-reviewed journal papers in the areas of benefits realisation and/or requirements management and/or FED based are identified on a pre-determined inclusion and exclusion criteria. Thirty-six requirements are identified as important in influencing use case changes important in design decision making broadly grouped into nine major categories. Following analysis, this research finds little evidence supporting an integrated requirements management practice and understanding to support design decision making. The research further finds bias in current research discourse towards four requirements categories (technical, economics, governance and environment); and 14 requirements, dominated by three strategic values, collaboration and project governance, with over 80% share of literature. The least 14 requirements such as “flow of spaces, social status/aspiration, mobility and integrated design” among others only account for less than 10% of literature. The authors argue for new research to bridge this gap, highlight the essential role of requirements management and broaden understanding to improve benefits realisation, particularly for FED processes.

Cloud computing has significantly benefited today's environment of IT industry through its mobility, sustainability, security, cost savings and several other important features. The risk of data loss on cloud in case of dealing with hardware and software is relatively small. However, the issue of data security becomes imminent when we are storing personal data on the cloud which is not transparent to users. In this paper, we introduce a new entity in terms of a virtual machine that provides services and assurance beyond service level agreement (SLA). In the proposed model, a role of data handling and security is assured with association of third party auditor (TPA) by the virtual machine. We further demonstrate the applied technique for encryption, decryption and integrity verification modules. We also upgrade the entropy of the advanced encryption standard (AES) with a variant of secret sharing scheme in the environment of cloud simulator.
