Cloud Data Security Based on Data Partitions and Multiple Encryptions

摘要

The benefits of cloud computing are measured services, unlimited and automatic access and release of resources. But, data security issues such as stealing credentials, unauthorized exposure of data may scare businesses away. Many popular security techniques try to protect data in cloud. Still, various state-of-art techniques are emerging as new types of attacks are being exposed. This paper proposes a scheme that is based on partitioning the plain text into different data parts, generating multiple cipher texts for each part and each cipher text is stored in different centers of cloud storage. Decryption of a data part is done with all cipher texts of each data part and a private key. By obtaining all plain texts data parts by this method, the original text is delivered to authorized user while preserving confidentiality and integrity.
