A Hardware One-Time Pad Prototype Generator for Localising Cloud Security
(2017)
Tobin, Paul; Tobin, Lee; mcKeever, Michael; Blackledge, Jonathan, Professor
Abstract:
<p>In this paper, we examine a system for encrypting data before storing in the Cloud. Adopting this system gives excellent security to stored data and complete control for accessing data by the client at different locations. The motivation for developing this personal encryption came about because of poor Cloud security and doubts over the safety of public encryption algorithms which might contain backdoors. However, side-channel attacks and other unwanted third-party interventions in Cloud security, probably contribute more to the poor security record history. These factors led to the development of a prototype for personalising security locally which defeats cryptanalysis. The key distribution problem associated with random binary sequences called one-time-pads, does not exist for one-to-Cloud applications, unlike bi-directional communications where it was a big issue. The random binary sequences were generated from chaotic analogue oscillators with initial conditions from ...

Cloud Computing for Schools
(2010)
O'Doherty, Shane
Abstract:
<p>This project evaluates previous Information and Communication Technology policy and practice relating to primary schools in Ireland with a view to suggesting a better way forward in light of advances in ICT, such as the availability of fast broadband services, including fibre broadband, browser-based applications and the advent of cloud computing. Cloud computing refers to the Internet as a source of both software programs and also data retention, in effect the Internet provides the software and data services via browsers to users who may remain entirely unaware of the technology at work, uncluttered by hardware or software licensing issues or problems and free to concentrate on activity and usage. More specifically, this study questions the wisdom of large spending on soon-to-be obsolete hardware and software packages in light of the fact that Internet browsers now offer access to both software applications and data storage without requiring users to have hard disks of the...

Cloud Computing:Strategies for Cloud Computing Adoption
(2010)
Shimba, Faith
Abstract:
The advent of cloud computing in recent years has sparked an interest from different organisations, institutions and users to take advantage of web applications. This is a result of the new economic model for the Information Technology (IT) department that cloud computing promises. The model promises a shift from an organisation required to invest heavily for limited IT resources that are internally managed, to a model where the organisation can buy or rent resources that are managed by a cloud provider, and pay per use. Cloud computing also promises scalability of resources and on-demand availability of resources. Although, the adoption of cloud computing promises various benefits to an organisation, a successful adoption of cloud computing in an organisation requires an understanding of different dynamics and expertise in diverse domains. Currently, there are inadequate guidelines for adopting cloud computing and building trust. Therefore, this research project aims at developing...

Context aware mobile cloud services: a user experience oriented middleware for mobile cloud computing
(2016)
O'Sullivan, Michael J.; Grigoras, Dan
Abstract:
Existing research on implementing the mobile cloud computing paradigm is typically based on offloading demanding computation from mobile devices to cloud-based servers. A continuous, high quality connection to the cloud infrastructure is normally required, with frequent high-volume data transfer, which can have a detrimental impact on the user experience of the application or service. In this paper, the Context Aware Mobile Cloud Services (CAMCS) middleware is presented as a solution that can deliver an integrated user experience of the mobile cloud to users. Such an experience respects the resource limitations of the mobile device. This is achieved by the Cloud Personal Assistant (CPA), the user’s trusted representative within CAMCS, which completes user-assigned tasks using existing cloud-based services, with an asynchronous, disconnected approach. A thin client mobile application, the CAMCS Client, allows the mobile user to send descriptions of tasks to his/her CPA, and view task...

Development of a Cloud Solution for SMEs in the Irish Construction Industry
(2010)
Hore, Alan V; Redmond, Alan; West, Roger
Abstract:
<p>There is a strong emerging trend within the Information Communication Technology (ICT) sector for replacing traditional packaged desktop applications with Web based, outsourced products and services. The drive for this innovative solution is its contribution to enabling software to be developed, delivered and consumed in discrete chunks (known as services) liberating the users from traditional computing and providing services accessible across a range of devices and appliances. The objective of this paper is to report on the progress towards defining this Web based service, commonly known as ‘Cloud computing’, for Small to Medium Size Enterprises (SMEs) in the Irish construction industry. The authors will present the results of a Construction IT Alliance (CITA) Enterprise Innovation Network (EIN) marketplace survey that combined vendor and consumer attitudes. This paper will also act as recommendation for the future development of a re-engineered software solution that will...

Enterprise Cloud Adoption - Cloud Maturity Assessment Model
(2017)
Conway, Gerry; Doherty, Eileen; Carcary, Marian; Crowley, Catherine
Abstract:
The introduction and use of cloud computing by an organization has the promise of significant benefits that include reduced costs, improved services, and a pay-per-use model. Organizations that successfully harness these benefits will potentially have a distinct competitive edge, due to their increased agility and flexibility to rapidly respond to an ever changing and complex business environment. However, as cloud technology is a relatively new phenomenon, there is still a lot to learn about the adoption and use of cloud, including issues such as security, data protection, interoperability, service maturity, and return on investment. These issues need to be considered,and if possible remediated,toenablean organization to effectivelymanage itscloud adoption journey. This paper describesan assessmentmodelthat was developed by the Innovation Value Institute (IVI) using a multi method, two-phasedapproach. The first ph...

Integrating mobile and cloud resources management using the cloud personal assistant

Integrating mobile and cloud resources management using the cloud personal assistant
(2015)
O'Sullivan, Michael J.; Grigoras, Dan
Abstract:
The mobile cloud computing model promises to address the resource limitations of mobile devices, but effectively implementing this model is difficult. Previous work on mobile cloud computing has required the user to have a continuous, high-quality connection to the cloud infrastructure. This is undesirable and possibly infeasible, as the energy required on the mobile device to maintain a connection, and transfer sizeable amounts of data is large; the bandwidth tends to be quite variable, and low on cellular networks. The cloud deployment itself needs to efficiently allocate scalable resources to the user as well. In this paper, we formulate the best practices for efficiently managing the resources required for the mobile cloud model, namely energy, bandwidth and cloud computing resources. These practices can be realised with our mobile cloud middleware project, featuring the Cloud Personal Assistant (CPA). We compare this with the other approaches in the area, to highlight the impor...

Investigation into a best practice model for providing an integrated user experience with mobile cloud applications

O'Sullivan, Michael J.
Abstract:
Mobile Cloud Computing promises to overcome the physical limitations of mobile devices by executing demanding mobile applications on cloud infrastructure. In practice, implementing this paradigm is difficult; network disconnection often occurs, bandwidth may be limited, and a large power draw is required from the battery, resulting in a poor user experience. This thesis presents a mobile cloud middleware solution, Context Aware Mobile Cloud Services (CAMCS), which provides cloudbased services to mobile devices, in a disconnected fashion. An integrated user experience is delivered by designing for anticipated network disconnection, and low data transfer requirements. CAMCS achieves this by means of the Cloud Personal Assistant (CPA); each user of CAMCS is assigned their own CPA, which can complete user-assigned tasks, received as descriptions from the mobile device, by using existing cloud services. Service execution is personalised to the user's situation with contextual data, ...

Mobile cloud healthcare systems using the concept of point–of–care
(2017)
Alshareef, Hazzaa Naif
Abstract:
Recent years have witnessed a rapid growth in delivering/accessing healthcare services on mobile devices. An example of a health practice/application that is benefiting from the mobile evolution is m–health, which is aimed at providing health services to mobile devices on the move. However, mobile devices have restricted computational and storage capacity, and run on batteries that have limited power. These limitations render m–health unable to run the demanding tasks that may be required for accessing/providing health services. The mobile cloud has recently been proposed as a solution for dealing with some of the limitations of mobile devices, such as low storage and computing capacity. However, introducing this solution into the m–health field is not straightforward, as the integration of this technology has specific limitations, such as disconnection issues and concerns over privacy and security. This thesis presents research work investigating the ability to introduce mobile clo...

Self-learning cloud controllers: fuzzy Q-learning for knowledge evolution
(2015)
Jamshidi, Pooyan; Sharifloo, Amir; Pahl, Claus; Metzger, Andreas; Estrada, Giovani
Abstract:
Auto-scaling features enable cloud applications to maintain enough resources to satisfy demand spikes, reduce costs and keep performance in check. Most auto-scaling strategies rely on a predefined set of rules to scale up/down the required resources depending on the application usage. Those rules are however difficult to devise and generalize, and users are often left alone tuning auto-scale parameters of essentially blackbox applications. In this paper, we propose a novel fuzzy reinforcement learning controller, FQL4KE, which automatically scales up or down resources to meet performance requirements. The Q-Learning technique, a model-free reinforcement learning strategy, frees users of most tuning parameters. FQL4KE has been successfully applied and we therefore think that a fuzzy controller with Q-Learning is indeed a promising combination for auto-scaling resources.

Abstract:
Cloud computing represents a significant economic opportunity for Europe. However, this growth is threatened by adoption barriers largely related to trust. This position paper examines trust and confidence issues in cloud computing and advances a case for addressing them through the implementation of a novel trustmark scheme for cloud service providers. The proposed trustmark would be both active and dynamic featuring multi-modal information about the performance of the underlying cloud service. The trustmarks would be informed by live performance data from the cloud service provider, or ideally an independent third-party accountability and assurance service that would communicate up-to-date information relating to service performance and dependability. By combining assurance measures with a remediation scheme, cloud service providers could both signal dependability to customers and the wider marketplace and provide customers, auditors and regulators with a mechanism for determining...

User-centric adaptation of multi-tenant services: preference-based analysis for service reconfiguration
(2014)

Abstract:
Multi-tenancy is a key pillar of cloud services. It allows dif- ferent tenants to share computing resources transparently and, at the same time, guarantees substantial cost savings for the providers. However, from a user perspective, one of the major drawbacks of multi-tenancy is lack of con gura- bility. Depending on the isolation degree, the same service instance and even the same service con guration may be shared among multiple tenants (i.e. shared multi-tenant ser- vice). Moreover tenants usually have di erent - and in most of the cases - con icting con guration preferences. To over- come this limitation, this paper introduces a novel approach to support user-centric adaptation in shared multi-tenant services. The adaptation objective aims to maximise ten- ants' satisfaction, even when tenants and their preferences change during the service life-time. This paper describes how to engineer the activities of the MAPE loop to sup- port user-centric adaptation, and focuses on t...
