Attribute-Based Data Sharing Scheme Revisited in Cloud Computing

Abstract

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.
 
We propose an Attribute-Based Data Sharing Scheme Revisited in Cloud Computing improved two-party key issuing protocol that can guarantee that neither key authority nor cloud service provider can individually compromise a user’s entire secret key..

Conclusion

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.
