Analysis of One Secure Anti-Collusion Data Sharing Scheme for Dynamic Groups in the Cloud
摘要
We show that the scheme [IEEE TPDS, 27(1), 2016, 40-50] is awed because the group manager cannot complete his computational task in the registration phase. Actually, the designers of the scheme have misunderstood the concept of public key which is usually associated with an asymmetric encryption algorithm. Besides, the mechanism that the group manager has to re-encrypt all data stored in the cloud after a member is revoked, is somewhat infeasible because of its inefficiency.
