With the character of low maintenance, cloud
computing provides an economical and efficient solution for
sharing group resource among cloud users. Unfortunately,
sharing data in a multi-owner manner while preserving data
and identity privacy from an un trusted cloud is still a
challenging issue, due to the frequent change of the
membership. A secure multi owner data sharing scheme,
named Mona, for dynamic groups in the cloud is proposed.
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 revoked users. In addition, to it analyzing
the security of the scheme with rigorous proofs, and
demonstrate the efficiency of the scheme in the experiments.
