摘      要：In recent decades, a number of protocols for Remote data integrity checking(RDIC) have been proposed. Identity(ID) based RDIC protocols are constructed to guarantee cloud data integrity and data privacy. The known protocols for RDIC always assume that the Private key generator(PKG) is a trusted one, but in real-world applications by corrupt PKG, malicious Cloud server(CS) can easily cheat the third party auditor that the data owner’s outsourced data are kept safe through the data has been deleted or altered. In this paper, we explore the novel model of RDIC with untrusted PKG and malicious CS, by employing the partial key method and Authentication, authorization, accounting(AAA) *** construct a new ID-based RDIC, which provides the ID revocation and key updation. The experimental evaluations show that our scheme is more efficient than known ones.
