Study on Mobile Large Data Storage Security in Cloud Computing Environment

Abstract

In this thesis, data security in cloud computing is regarded as the research object. First of all, the definitions, model, structure, application, research organization and related knowledge of cloud computing is introduced. Then, the data security assurance methods which used in this thesis including symmetric and asymmetric encryption system, attribute-based encryption algorithm and Merkle Hash Tree are discussed. The security challenge, advantage, protective measures and security architecture of data security based in cloud computing environment are summarized with many cloud computing characteristics, such as massive, virtualization, dynamics and expansibility.
