—Mobile Ad hoc Networks (MANET) have been highly vulnerable to attacks due to the dynamic nature of its network infrastructure. Among these attacks, routing attacks have received considerable attention since it could cause the most devastating damage to MANET. Even though there exist several intrusion response techniques to mitigate such critical attacks,(More)
—Cloud computing is an emerging computing paradigm where computing resources are provided as services over Internet while residing in a large data center. Even though it enables us to dynamically provide servers with the ability to address a wide range of needs, this paradigm brings forth many new challenges for the data security and access control as users(More)
—In modern healthcare environments, healthcare providers are more willing to shift their electronic medical record systems to clouds. Instead of building and maintaining dedicated data centers, this paradigm enables to achieve lower operational cost and better interoperability with other healthcare providers. However, the adoption of cloud computing in(More)
— Organizations and enterprises have been outsourc-ing their computation, storage, and workflows to Infrastructure-as-a-Service (IaaS) based cloud platforms. The heterogeneity and high diversity of IaaS cloud environment demand a comprehensive and fine-grained access control mechanism, in order to meet dynamic, extensible, and highly configurable security(More)
