Implementation of Decentralized Access Control with Anonymous Authentication in Cloud

Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. Cloud computing is a metaphor for the internet. It is a internet based computing. Heart of cloud computing is virtualization. The data stored in cloud is a very sensitive for example medical records, social records. In traditional days access control used in cloud are centralized in nature and it uses a single KDC.

The project is based on decentralized access control scheme for secure data storage in clouds that maintain anonymous verification. In this project, the cloud verifies the authenticity of the series without knowing the user's identity before storing data. It provides decentralized authentication and registered users can access the data from cloud. It also has the added feature of access control in which only authorized users are able to decrypt the stored information. It supports creation, modification and reading the data stored in cloud. The communication, computation, and storage overheads are similar to centralized approaches.
