With the rapid development of the computer technology, cloud-predicated accommodations has become a hot topic. Cloud-predicated accommodations not only provide users with services, but withal bring many security issues. Consequently, the study of access control scheme to bulwark user’s privacy in cloud environment is of great consequentiality. In this paper, we implement an access control system with privilege disunion predicated on privacy aegis (PS-ACS).In this scheme we divide the users into two domains. They are personal domain (PSD) and public domain (PUD).For the users of PSD we set the read and write access permissions. The Key- Aggregate Encryption (KAE) is utilized to implement the read access sanction. It will ameliorate the access efficiency. Ameliorated Attribute-predicated Signature (IABS) is utilized to determine the users write access. For the users of PUD hierarchical attribute-predicated encryption (HABE) is implemented to eschew the issues of single point of failure and perplexed key distribution. Function and performance testing result shows that the PS-ACS scheme can achieve aegis in cloud predicated accommodations.
