Abstract:-Benefit since cloud computing, users can get an effective and cheap approach for
information allocation between group members within the cloud with the characters of low
maintenance and little management value. Meanwhile, we should give security guarantees for the
sharing information files since they are outsourced. Unfortunately, because of the frequent
modification of the attachment, allocation information while provided that privacy-preserving is
still a challenging issue, especially for an untrusted cloud owed to the collusion hit. Moreover, for
existing schemes, the security of key distribution relies on the secure line, however, to have such
channel is a strong assumption and is difficult for practice. In this paper, we propose a protected
data distribution system for energetic members. Firstly, we propose a secure method for key
distribution while not any protected communication channel and the user can strongly acquire
their non-public keys from group manager. Secondly, our design can attain fine-grained access
organize, any user within the group can use the source in the cloud and revoked users cannot
access the cloud again after they're revoked. Thirdly, we can shield the scheme from collusion
attack, which means that revoked users cannot get the initial file even though they conspire with
the untrusted cloud. In our approach, by leveraging polynomial operate; we can achieve a secure
user revocation scheme. Finally, our scheme will succeed fine potency, which means that previous
users needn't to update their non-public keys for matters either a replacement user joins within the
group or a user is revoked from the group.
