摘要：
CP-ABE (Cipher-text Policy Attribute Based Encryption) can help providing reliable, fine-grained access control in untrusted cloud storage environment, since users can access to data files only if their attributes satisfy the access policies associated with the files. However, CP-ABE has two main drawbacks: its policies are not expressed using standard languages and it can't support non-monotonic policies. So we extended CP-ABE to support XACML (eXtensible Access Control Markup Language) based policy transformation and to support logical NOT in policies through De Morgan's Laws. And then we applied it to a secure overlay cloud storage system called FADE to deploy access control for Amazon S3 cloud storage service. The simulation results show that our proposal is practical and time efficient.
