Context: Scientific computing in the 21st century has evolved from fixed to distributed work environment. The current trend of Cloud Computing (CC) allows accessing business applications from anywhere just by connecting to the Internet. Evidence shows that, switching to CC organizations' annual expenditure and maintenance are being reduced to a greater extent. However, there are several challenges that come along with various benefits of CC. Among these include security aspects.

Cloud computing is one of the most promising technologies for backup and data storage that provides flexible access to data. Cloud computing plays a vital role in remote backup. It is so unfortunate that this computing technique has flaws that thrilled and edgy end users in implementing it effectively. These flaws include factors like lack of integrity, confidentiality and privacy to information. A secure cloud is impossible unless the computer-generated environment is appropriately secured. In any form of technology it is always advisable that security challenges must be prior identified and

The cloud database is a relatively new type of distributed database that allows companies and individuals to purchase computing time and memory from a vendor. This allows a user to only pay for the resources they use, which saves them both time and money. While the cloud in general can solve problems that have previously been too costly or time-intensive, it also opens the door to new security problems because of its distributed nature. Several approaches have been proposed to increase the security of cloud databases, though each seems to fall short in one area or another. This thesis presents

Institutions and enterprises are moving towards more service availability, managed risk and at the same time, aim at reducing cost. Cloud Computing is a growing technology, thriving in the fields of information communication and data storage. With the proliferation of online activity, more and more information is saved as data every day. This means that more data is being stored in the cloud than ever before. Data that is stored online often holds private information – such as addresses, payment details and medical documentation. These become the target of cyber criminals. There is therefore g

Security, especially security compliance, is a major concern that is slowing down the large scale adoption of cloud computing in the enterprise environment. Business requirements, governmental regulations and trust are among the reasons why the enterprises require certain levels of security compliance from cloud providers. So far, this security compliance or auditing information has been generated by security specialists manually. This process involves manual data collection and assessment which is slow and incurs a high cost. Thus, there is a need for an automated compliance tool to verify an

Throughout the recent years cloud computing has gained large popularity in the information technology domain. Despite its popularity, there are many organizations that are lacking broader understanding of implementing and utilizing cloud computing for business and operating purpose due to the existing vagueness regarding its cost and security effect associated. It is argued that the main attractiveness of cloud computing for organizations is its cost effectiveness, whilst the major concern relates to the risks for security. Accordingly, more effort has been made in exploring these issues of cl

Context: Cloud computing is a prospering technology that most organizations are considering for adoption as a cost effective strategy for managing IT. However, organizations also still consider the technology to be associated with many business risks that are not yet resolved. Such issues include security, privacy as well as legal and regulatory risks. As an initiative to address such risks, organizations can develop and implement SLA to establish common expectations and goals between the cloud provider and customer. Organizations can base on the SLA to measure the achievement of the outsource

Although cloud computing is the major hype nowadays, it is actually a relatively old concept which can be dated back to the 1950s. Then, AT&T was developing a centralized infrastructure and storage space, where their customers could connect to using advanced telephones. Cloud computing works in a similar fashion, where customers subscribe to centralized service models. The models are separated in three main categories; Software-as-a-Service (SaaS), Platform-as-a-Service (PaaS) and Infrastructure-as-a-Service (IaaS). The cloud is a multi-tenant environment, i.e., several custome

Cloud Computing has advanced to the point where it may be considered an attractive proposition for an increasing number of South African organisations, yet the adoption of Cloud Computing in South Africa remains relatively low. Many organisations have been hesitant to adopt Cloud solutions owing to a variety of inhibiting factors and concerns that have created mistrust in Cloud Computing. One of the top concerns identified is security within the Cloud Computing environment.

Technological innovation has enabled tiny devices to participate in pervasive com- puting. Such devices are particularly vulnerable to security and privacy threats, because of their limited computing resources and relatively weak physical security. We investigate possible cryptographic solutions to security and privacy problems arising in two kinds of emerging pervasive computing networks: Personal Area Net- works (PANs) and the EPCglobal Network. A number of key management schemes have been proposed for use in PANs, but these schemes only support key management within a PAN. However, as peopl

Computer and Information Science<br>Ph.D.<br>The growing concerns in term of the privacy of data stored in public cloud have restrained the widespread adoption of cloud computing. The traditional method to protect the data privacy is to encrypt data before they are sent to public cloud, but heavy computation is always introduced by this approach, especially for the image and video data, which has much more amount of data than text data. Another way is to take advantage of hybrid cloud by separating the sensitive data from non-sensitive data and storing them in trusted private cloud and un-trus

Les avancées des techniques de virtualisation et la maturité des langages d'orchestration ont contribué à la conception et au déploiement de services cloud composites. Ces services cloud peuvent être sujets à des changements dans le temps, en raison de la migration de leurs ressources. Cela peut introduire de nouvelles vulnérabilités, qui compromettent un service cloud dans son ensemble. Dans ce contexte, cette thèse propose d'améliorer et d'automatiser la sécurité des services cloud composites selon trois axes principaux. Le premier axe consiste en un framework de sécurité automatique basé su

Encryption helps to ensure that information within a session is not compromised. Authentication and access control measures ensure legitimate and appropriate access to information, and prevent inappropriate access to such resources. While encryption, authentication and access control each has its own responsibility in securing a communication session, a combination of these three mechanisms can provide much better protection for information. This thesis addresses encryption, authentication and access control related problems in cloud and distributed environments, since these problems are ver
