OPeNDAP Hyrax Back-End Server (BES): Authentication and Authorization
Creators: name: West, Patrick

Year: 2007

description: This slide deck was presented as part of the OPeNDAP Developer's Workshop, Winter 2007 that was held from February 21-23, 2007 at the NCAR Foothills Laboratory in Boulder, CO. 

Abstract: 

The Coupling, Energetics and Dynamics of Atmospheric Regions (CEDAR) and the Earth System Grid (ESG) projects rely on OPeNDAP Back-End Server (BES) for the purpose of data distribution. Each of these systems requires different forms of authentication and authorization. To facilitate these different requirements, as presented in use-cases for each of the systems, we have enhanced the modular design of the BES by including security for establishing connections. In order to achieve this, we have combined the Point to Point Transfer (PPT) protocol used by the BES with the Secure Socket Layer (SSL) handshake protocol. The design, implementation and resulting architectures are presented.
