Secure Multi-Owner Data Sharing for Dynamic Groups in the Cloud
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 7
Abstract
Cloud computing is renowned as an alternative to Traditional information technology due to its inherent resourcesharing and low-maintenance characteristics. With the nature of low preservation, cloud computing provides an inexpensive and capable elucidation for giving out group resource among cloud users. Unfortunately, sharing data in a multi-owner approach while preserving data and identity privacy from an untrusted cloud is still a challenging issue; due to the recurrent alter of the membership. In this paper, we propose a safe and sound multiowner data sharing scheme, for dynamic groups in the cloud. By leveraging group signature and active 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, we analyze the security of our scheme with rigorous proofs, and demonstrate the efficiency of our scheme in experiments.
