Investigations on Decentralized Access Control Strategies for Anonymous Authentication of Data Stored In Clouds

In order to achieve safe storage, policy based file access control, policy based file assured deletion and policy based renewal of a file stored in a cloud

In [13], revocation involved changing the public and secret keys of the minimal set of attributes which are required to decrypt the data.. We do not consider this approach be-

We can resolve this problem by encryption, that is encrypt data then upload into the cloud but unfortunately data sharing in cloud with securely is not a easy task because

Our scheme also has the added feature of access control in which only valid users are able to decrypt the stored information.[8] The scheme prevents replay attacks and

S Divya Bharathy and T Ramesh[14] intrdused the concept of privacy preserving access control scheme for data storage, which supports anonymous authentication and performs

c) Monotone span programs. Any access structure can be converted into a Boolean function. a) Distributed access control of the data stored in cloud. Only authorized users with

Abstract — Motivated by the exponential growth and the huge success of cloud, we propose a new decentralized access control scheme for secure data storage in clouds
