We consider the problem of constructing a secure cloud storage service to which users outsource sensitive data for sharing with others where, in particular, the service provider is not completely trusted by the customer. Cloud storage service denotes an architectural shift toward thin clients and conveniently centralized provision of both computing and storage resources. When utilizing cloud storage for secure data sharing, one of the main motivating problems of this architecture is providing thin clients with both strong data confidentiality and flexible fine-grained access control without imposing additional cost on them (clients). To achieve this goal, we propose a novel data sharing protocol by combining and exploiting two of the latest attribute based cryptographic techniques, attribute-based encryption (ABE) and attribute-based signature (ABS). Furthermore, we also give a detailed comparison of our scheme with several latest existing schemes.
