An efficient algorithm for data security in Cloud storage

Cloud computing has now become a major trend, it is a new data hosting technology that is Very popular in recent years thanks to the amortization of costs it induces to companies. In this paper we present the major security issues in cloud computing and we also propose a simple, secure, and privacy-preserving architecture for inter-Cloud data sharing based on an encryption/decryption algorithm which aims to protect the data stored in the cloud from the unauthorized access.
