A Survey Paper on MONA: Secure Multi-Owner Data Sharing for Dynamic Groups in the Cloud

Cloud computing is associate degree rising computing paradigm within which resources of the computing infrastructure area unit provided as services over the net. As promising because it is, this paradigm conjointly brings forth several new challenges for knowledge security and access management once users confidential against untrusted servers, existing solutions sometimes apply cryptological ways by revealing knowledge cryptography keys solely to approved users. one among the largest considerations with cloud knowledge storage is that of knowledge integrity verification at untrusted servers. To preserve knowledge privacy, a basic resolution is to encode knowledge files, so transfer the encrypted knowledge into the cloud. To resolve this downside recently the simplest economical technique Anglesey given for secured multi owner knowledge sharing in but we have a tendency to known some limitations within the same approach in terms of responsibleness and quantifiability. Therefore during this paper we have a tendency to area unit more extending the fundamental Anglesey by adding the responsibleness still as rising the quantifiability by increasing the quantity of cluster managers dynamically.
