Ensuring Data Integrity Using Cooperative Provable Data Possession for Multi Cloud Environment

Abstract

Cloud computing is a new and fast growing technology that offers an innovative, efficient and scalable business model for organizations. Cloud computing is type of computing where resources are shared rather than having local servers or personal devices to handle various applications. Cloud computing is a type of internet based computing where different services like server, storage, application, and network are delivered to the organizations. Although almost every business organization is going to adopt this technology due to its various advantages. When cloud computing become more perfect organizations and user will store enormous amount of data on remote cloud storage to achieve remote access, reduced cost, data collection and sharing of other services. To access services from cloud user can have account associated with single and multiple cloud service providers (SPs). Important aspect for cloud computing environment is to maintain integrity of stored data. Implementation of encryption of the information is done in such a way that it will be impossible for the attackers to read the resources sent on the web. Advanced Encryption Standard (AES) and Elliptic Curve Cryptography (ECC) are the methods used for the encryption. Result will be text (cipher) which is decrypted on the receiver’s side. AES and ECC algorithm implemented together to provide sound security.
