A Secure Anti-Collusion Data Sharing Scheme for Dynamic Groups in the Cloud

Abstract

Benefited from cloud computing, users can achieve an effective and economical approach for data sharing among group members in the cloud with the characters of low maintenance and little management cost. A Secure Anti-Collusion Data Sharing Scheme for Dynamic Groups in the Cloud Meanwhile, we must provide security guarantees for the sharing data files since they are outsourced.
A Secure Anti-Collusion Data Sharing Scheme for Dynamic Groups in the Cloud Unfortunately, sharing data while providing privacy preservation is still a challenging issue due to the frequent change in membership, especially for an untrusted cloud due to the collusion attack. Moreover, for existing schemes, the security of key distribution is based on the secure communication channel, however, to have such channel is a strong assumption and is difficult for practice.

Advantages

  • It supports dynamic group efficiency.
  • The other user in the group need to update or recomputed their private key when new user joins or user revoked from the group.
  • The user can securely obtain their private key from the group manager without any certificate authority.
  • Propose a secure data sharing scheme which can be protected from collusion attack

Conclusion

In this paper, we outline a plan for the sharing of information against agreement for element bunches in the cloud. In our plan, customers can securely acquire their private keys from collecting Certificate Authorities director and secure correspondence channels. Likewise, our plan can bolster dynamic gatherings proficiently, when another client joins in the gathering or a client is denied from the gathering, the private keys of alternate clients don’t should be recomputed and redesigned.
