A Review on Cryptography in Cloud Computing

Abstract

Cloud computing is the delivery of computing services over the web instead of keeping files on a proprietary disk drive or local memory device. Computing services can include servers, storage, databases, networking, software. The main reason and great advantage for using the cloud are that the user can store and access the stored data in the cloud from anywhere anytime and getting all its services for a low cost. Despite, Security has always been a big concern with cloud computing because the information stored in the cloud is not directly maintained by the customer. When the user uploaded or stored data during a cloud computing service, the info owners are unlikely to understand the path via which their data is being transmitted. The user is unknown to the fact whether the information is being collected, analyzed, and accessed by a third party or not. To overcome the security issues various cryptography algorithm is proposed. This paper focused on the basics of cloud computing and discussed various cryptography algorithms present in the existing work.
