摘要：Data access control is an efficient way to provide the data security in the cloud but due todata outsourcing over untrusted cloud servers, the data access control becomes a challenging issue in cloud storagesystems. Attribute-based Encryption (ABE) technique is regarded as a most trustworthy cryptographicconducting tool to guarantee data owner’s direct control on their data in public cloud storage. The previous ABEschemes involve only one authority to maintain the complete attribute set, which can bring a single-point hindrance onboth security and performance. Paper proposed the design, an expressive, efficient and revocable decentralized mannerdata access control scheme for multi-authority cloud storage systems, where there are multiple authorities exist andevery authority is able to issue attributes independently.
