In recent years, there has been considerable interest in Intercloud. Inspired by the Internet, Intercloud allows clouds to be interconnected, forming a cloud/network of clouds. With Intercloud, many new and powerful cloud computing services can be provided. One of the basic problems with supporting Intercloud is the need to address the issue of how to ensure that clouds can communicate with each other...
Cloud computing model has been among the main stream popular new technologies by providing services such as software, platform and infrastructure. In the process of providing better services for customers, cloud service providers have developed proprietary standards on how cloud application interacts with their cloud. This has been limiting the cloud adoption because of the vendor lock-in and portability...
The IEEE P2302 Intercloud WG conducts work since 2011 on the project Standard for Intercloud Interoperability and Federation with the goal to define a standard architecture and building components for large-scale interoperability of independent cloud providers. While the standardization process has achieved fine-grained definitions of several Intercloud components, a deployment of the Intercloud to...
Ciphertext-Policy Attribute Based Encryption (CP-ABE) is recognized as an important data protection mechanism in cloud computing environment for its flexible, scalable and fine-grained access control features. For enhancing its security, efficiency and policy flexibility, researchers have proposed different schemes of CP-ABE which have different kinds of access policy structures. However, as far as...
In the contemporary cloud computing environment, the various cloud providers adopt different architectures for their systems and usually these are not compatible. The scalable exchange of information about these heterogeneous resources is often not addressed; still this represents an interesting challenge, since different Cloud systems and vendors have different ways to describe and invoke their services,...
This paper presents a fully secure (adaptive-predicate unforgeable and private) attribute-based signature (ABS) scheme in the standard model. The security of the proposed ABS scheme is proven under standard assumptions, the decisional linear (DLIN) assumption and the existence of collision resistant (CR) hash functions. The admissible predicates of the proposed ABS scheme are more general than those...
The integration of cloud and grid infrastructures is still of current interest, because it provides a way for the scientific area to ensure sustainability of well engineered grid applications. The integration of well established grid infrastructures with cloud systems also fosters their complementary usage, simplified migration of applications, as well as efficient resource utilization. In this paper,...
