Cloud Computing, Security, Privacy, Encryption Algorithms.

Cloud security is an evolving sub-domain of computer security, network security, and, more broadly, information security. It refers to a broad set of policies, technologies, and controls deployed to protect data, applications, and the associated infrastructure of cloud computing. Encryption is a well known technology for protecting sensitive data. Use of the combination of Public and Private key encryption to hide the sensitive data of users, and cipher text retrieval. This paper presents an overview of security issues and also analyzes the feasibility of applying encryption algorithm for data security and privacy in cloud Storage. It also tried to cover the various algorithms used by researchers to solve the open security problems.
