Abstract

With the character of low management, cloud computing provides an various and efficient solution for sharing group tasks among cloud users. Unfortunately, sharing data in a multi-owner manner while handling data and identity privacy from an untrusted cloud is still a challenging issue, due to the frequent gradiant of the membership. In this paper, a secure multi owner data sharing scheme for dynamic groups in the cloud. By leveraging group signature and dynamic broadcast encryption techniques, any cloud user can anonymously share data with others. Meanwhile, the storage overhead and encryption computation cost of our scheme are independent with the number of users. In addition, we analyze the security of our scheme with rigorous proofs, and demonstrate the efficiency of our scheme in experiments.
