Attribute-Based Data Sharing Scheme Revisited in Cloud Computing
Ciphertext-policy attribute-based encryption (CP-ABE) is a very promising encryption technique for secure data sharing in cloud computing. Moreover, the attribute with arbitrary state can not support most CP-ABE schemes. In this Attribute-Based Data Sharing Scheme Revisited in Cloud Computing paper, we revisit the attribute-based data sharing scheme to solve the key escrow issue, but also improve the expressiveness of the attribute, making the resulting scheme more friendly to cloud computing applications.

In this paper, we redesigned an attribute-based data sharing scheme in cloud computing. The improved key issuing protocol was presented to resolve the key escrow problem. It enhances data conﬁdentiality and privacy in cloud system against the managers of KA and CSP as well as malicious system outsiders, where KA and CSP are semi-trusted.
