Certain investigations on improving security of the cloud

Abstract

In the recent years, increase in the mobile devices and cloud processing the data stored in the cloud in the form of pictures, messages and texts. Cloud Service Providers (CSP) cannot trust entirely to authorize the services used by the clients. For enhancing the security in the cloud, new cyber security model is introduced with optimal key selection. In this k-Melded clustering algorithm is used to cluster the information which is secret. It is based on the data distance measure. The data is encrypted and stored in the cloud using Blowfish Encryption (BE). To improve the accuracy Improved Dragonfly Algorithm (IDA) is used. Cloud computing is an internet based service to provide the database storage, applications sharing and utilization of the IT resources for either by pay or at free cost. When the services are at free cost the access to the resources are in limited manner. The reason behind the development of cloud computing technology is to easy access of all resources with less cost. This technology is classified based on the service and architecture. Based on architecture the cloud computing is classified as private, public, hybrid and community cloud. Based on services it is classified as Infrastructure as a Service, platform as a Service and software as a service. A private cloud is one in which all infrastructures and the designed group accesses resources. The resources, which are common for all, and access based on money is called public cloud. Hybrid cloud is the one in which uses the private cloud for storage and public cloud for maintenance during high demand. In IaaS the third party for access provides the resources to the customers over the internet. The application and tools are developed by the third party host and provide as a service to the customer is PaaS. newline
