Abstract:
Cloud based data sharing is very imminent these days due to various number of advantages associated with it but to attain these fruitful advantages its integrity is required to be ensured. To gain secure communication and flawless data sharing we require strong authentication mechanism. Authentication mechanisms vary from situation to situation but the decentralized authentication mechanism is proven to be strong then centralized one. Different cloud authentication mechanisms have been proposed till now but all of them have their own limitations. These limitations arises a need for strong cloud authentication mechanism. A mechanism not very complex but strong enough to fulfil the need. Somewhat similar mechanism is proposed here in this thesis to provide reliable cloud based data sharing with less complexity.
