"云计算与PKI的网格认证与授权模型"

The document "Cloud Computing-Based PKI Grid Computing Authentication and Capability Authorization Model.pdf" discusses the increasing demand for sharing high-performance computing and distributed resources, and how traditional patterns of resource sharing cannot meet these needs. People now prefer to access computing, device, and storage resources from the internet whenever and wherever possible, similar to obtaining electricity. Additionally, they also prefer to search for required resources not only from local computers but also from different locations. The document explores the need for a new model for authentication and authorization in cloud and grid computing, based on Public Key Infrastructure (PKI). This model aims to provide secure and efficient access to resources while ensuring proper authentication and authorization. The abstract highlights the significance of this model in addressing the evolving requirements of resource sharing in the era of cloud computing. It emphasizes the need for a reliable and secure framework that can accommodate the increasing demand for computing resources and enable seamless access to distributed resources. Ultimately, the document emphasizes the role of PKI in establishing trust and security within the cloud and grid computing environments, thereby laying the foundation for effective resource sharing and collaboration.
