ENHANCED KEY DISTRIBUTION FOR FILE SHARING USING FUZZY AUTHORIZATION MODEL

A cloud system is difficult to synchronize login and authentication data between external clouds and internal systems without exposing internal security data. The cloud technologies are rapidly being adopted throughout the Information Technology (IT) due to their various attractive properties. In spite of their spread, they have raised a range of significant security and privacy concerns which interrupt their adoption in sensitive environments. The cloud computing technology provides IT services and resources to the customers through public network such as internet. The cloud computing services and infrastructure are mostly owned by a third party called cloud service providers. Cloud computing provides an innovative model for the organizations to use software applications, storage and processing capabilities of cloud without investing on the infrastructure. To ensure a correctness of users’ data in the cloud, we propose an effective and secure distributed model including a Self-Proxy Server (SPS) with self-created algorithm a distributed SPS dynamically interacts with Key Manager (KM) when the mobile users take on cloud service
