We propose the client-side AES256 encryption for a cloud SQL DB. We trust the safety of the cloud DBS run-time values, e.g., through a moving target defense. The client may send AES key(s) with the query. These become run-time values for on-the-fly decryption of ciphertext into plaintext for query evaluation. The DBS clears all these values at the query end at latest. The scheme functionally offers...
Cloud computing is the growing technology of large scale distributed computing. It provides on-demand access to distributed resources, which are available in open environment on paid basis. Because all most all the industries now a days want to use these services to reduce infrastructure and maintenance cost, therefore the load on cloud is increasing day by day. Balancing load is one of the biggest...
To meet ever-changing business needs, organizations are required to invest time and budget to scale up IT infrastructure such as hardware, software and services. However with own premises and investment in IT infrastructure scaling process can be slow and costly. Moreover, even if organizations scale up their IT infrastructure, these are hardly able to achieve the optimal utilization of the same....
Message Passing Interface (MPI) has been the predominant standardized system for writing parallel and distributed applications. However, while MPI has been the software system of choice for traditional parallel and distributed computing platforms such as large compute clusters and Grid, MPI is not the system of choice for cloud platforms. The primary reasons for this is the lack of low latency high...
The expectations of human desire on the technology are unlimited, so we need much more scalable system that manage themselves and fulfills our desire automatically. The current state of cloud computing infrastructure is not fully industrialized. To provide good quality of service (QOS) through cloud, the autonomic cloud computing, offers self- management properties of Autonomic Computing. With this...
The Cloud computing offers various services and web based applications over the internet. With the tremendous growth in the development of cloud based services, the security issue is the main challenge and today's concern for the cloud service providers. This paper describes the management of security issues based on Diameter AAA mechanisms for authentication, authorization and accounting (AAA) demanded...
Polygon overlay is one of the complex operations in computational geometry. It is applied in many fields such as Geographic Information Systems (GIS), computer graphics and VLSI CAD. Sequential algorithms for this problem are in abundance in literature but there is a lack of distributed algorithms especially for MapReduce platform. In GIS, spatial data files tend to be large in size (in GBs) and the...
Windows Azure is an emerging cloud platform that provides application developers with APIs to write scientific and commercial applications. However, the steep learning curve to understand the unique architecture of the cloud platforms in general and continuously changing Azure APIs specifically, make it difficult for the application developers to write cloud based applications. During our extensive...
We address the problem of providing users with the ability to assess the integrity of join results produced by external computational providers and computed over externally stored databases. Our approach relies on different mutually supporting techniques offering strong integrity protection guarantees at a limited cost. The application of the approach is completely transparent to the computational...
Cloud computing is becoming mainstream for High Performance Computing (HPC) application development over the last few years. However, even though many vendors have rolled out their commercial cloud infrastructures, the service offerings are usually only best-effort based, without any performance guarantees. Cloud computing effectively saves the eScience developer the hassles of resource provisioning...
