A Comparative Analysis of Security Algorithms Using Cryptographic Techniques in Cloud Computing

Cloud computing is a word which is describe different computing concepts which contains hugenumber of computers attached through a real-time communication like internet. Cloud computing is also called distributed computing over the network i.e. the ability to execute an application or a program on many computers at thesame time.Cloud Computing is an emerging technology in today’s business era. It allows convenient on demand access to resources that involve large number of computers connected through Internet. Public clouds vendors offer many resources such as application, storage, hardware, software’s etc. The security issues present in public cloud is more challenging. As everything is accessed publically; many users have the threat to store and retrieve it publically. As many organizations are moving data to the cloud there is a need to protect data against unauthorized access. Hence it is necessary to study the security issues in public cloud to secure data. The purpose of this paper is to provide an overview of pubic cloud computing and the security issues involved .This paper deals with the different algorithms or method used for securing data in public cloud.
