Analysis and Implementation of Encryption Algorithm Based on Cloud Computing Environment

[1] Cloud computing uses distributed architecture that enables use of scalable resources to provide computing services to cloud users using virtualization concept. It allows sharing of resources, scalability, elasticity, pay per usage and self-provisioning of resources from cloud providers.[2] Cloud computing moves application software and databases to large data centers where management of users’ data and services provided to them may not be fully secured. Communication between services providers and users using cloud network is done through service legal agreements (SLA). Because data transfer is between user and provider is done remotely; data security comes into concern as it opens the door to attacks such as intrusion. This paper is a study of encryption algorithms that are used to prevent intrusion with the intention to achieve data confidentiality, integrity and availability.
