Review of Key Management and Distribution Technique for Data Dynamics for Storage Security in Cloud Computing

Abstract

Data storage and retrieval is major issue in cloud environments. For data storage and retrieval used authentication and authorization process. The authentication and authorization process used cryptography technique. The cryptography technique provides symmetric and asymmetric crypto systems. The symmetric technique is week in compression of asymmetric technique. Various authors used the concept of asymmetric cryptography technique for the process of data over the cloud network. Authors also suggested the concepts of data dynamics for the proof of data retrieval. The proof of retrieval gives the concept of cloud based data auditing in block level. The access of data security faced a problem of encryption time of data and generation of key. The encryption time and generation of key take more time and invites third party attack on data integration. For the integration of data various algorithms are used. In this paper present the review of key generation and crypto analysis of data over cloud computing.
