A Note on One Secure Anti-Collusion Data Sharing Scheme for Dynamic Groups in the Cloud
Abstract
We remark that the scheme [IEEE TPDS, 27(1), 2016, 40-50] is flawed because the group manager cannot complete his computational task in the registration phase. Actually, they 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.
