SURVEY ON EFFICIENCY OF ENCRYPTION ALGORITHMS FOR CLOUD DATA SECURITY

Computer Engineering

Cloud computing is technology where the clients‟ can use high end services in form of software that reside on different servers and access data from all over the world. With a promising technology like this, it certainly abandons clients‟ privacy, management of data and services, putting new security threats towards the assurance of data in cloud. However, there are some security concerns when clients handle and share data in the cloud-computing environment. The security threats such as maintenance of data integrity, data hiding and data safety dominate clients concerns when the issues of cloud security come up. The big data and time-consuming encryption calculations related to applying any encryption method have proved as a hindrance in this field. Cryptography is knowledge of protecting the information for providing encryption techniques. In this paper we survey different security issues to cloud and different cryptographic algorithms adoptable to provide better security for the cloud.
