Abstract: Cloud Computing is an emerging technology which provides services on demand from shared pool of computing resources. Cloud computing has at its core services like platform, infrastructure and software as a service. Benefits of cloud storage are easy access, performance, high availability, cost efficiency and many others. So each and every organization is moving its data to the cloud, that means it uses the storage service provided by the cloud provider. So there is a need to protect the data against unauthorized access, modification or denial of services, data loss, data breach etc. Cloud security is must which will break the hindrance the acceptance of the cloud by the organizations. There are a number of security algorithms which may be implemented to the cloud. This paper is a survey of different security issues to cloud and different cryptographic algorithms adoptable to better security for the cloud.
