Mona: Secure Multi-Owner Data Sharing for Active Clusters in the Cloud

With the character of low upkeep, distributed computing gives a practical and productive answer for offering gathering asset among cloud clients. Shockingly, offering information in a multi-manager way while saving information and character protection from an untrusted cloud is still a testing issue, because of the continuous change of the enrollment. In this paper, we propose a protected multiowner information offering plan, named Mona, for element amasses in the cloud. By leveraging gathering signature and element show encryption systems, any cloud client can secretly impart information to others. In the meantime, the capacity overhead and encryption processing expense of our plan are autonomous with the quantity of denied clients. What's more, we investigate the security of our plan with thorough verifications, and exhibit the productivity of plan in tests.
