Abstract

Cloud computing is a big platform in the field of information technology for sharing data, resources, services and information by people of the world. The big problem in cloud is security, there are many method used to create secured data in cloud computing. Cryptography is one of an effective method to create secure communication in cloud computing especially in real time application where either symmetric key or a symmetric key can be applied. This paper presents a survey of many papers, which uses many encryption algorithms, many of them uses symmetric algorithms, the others papers uses asymmetric algorithm, and the others papers uses symmetric and asymmetric algorithms. The objective of this paper is to select or achieve suitable algorithm for their suitable application to encrypt data in a secure manner. The important goal of all papers in this survey is encryption time, decryption time, and throughput. In this paper a comprehensive survey has been done on the encryption algorithms in different applications that are similar to the applications in the cloud computing environment to select a suitable encryption algorithm to encrypt storage data in a secure manner
