Abstract:This paper analyzes the major cloud service providers ’key technology and security mechanism to extract the security requirement of current popular cloud services.And based on this analysis,this paper proposes a security framework which integrates cryptography algorithms as attribute-based encryption (ABE),proof of retrievability and proxy re-encryption to ensure the confidentiality,integrity,availability of cloud data.Furthermore,this paper implements a prototype of cloud storage service based efficient search system which employs ABE for fine-grained access control to protect unauthorized users ’access to sensitive file information (abstract,keywords)during search process and at the same time keeps the efficiency.
