NDG Security

NERC DataGrid Security is both an architecture and implementation for federated identity management and access control. It was first developed for the NERC DataGrid and has been extended to support the Earth System Grid Federation under development to support secure access to the federated data archive for CMIP5 (The Coupled Model Intercomparison Project).


  • ESGF: Federated Access control infrastructure for the Earth System Grid Federation, includes architectural overview
  • MashMyData: a NERC funded demonstrator project to create a portal environment for users to combine their data with datasets from distributed sources. It will trial access control with multihop delegation in a workflow.
  • NERC DataGrid 3 Project Activities?
  • Old Project home pages?

Development Activities

  • ndg_xacml: Python implementation of XACML, eXtensible Access Control Markup Language developed for CEDA (Centre for Environmental Data Archival).

netCDF C API Extension for SSL based authentication with OPeNDAP

  • netCDF C API Extension: modifications to the netCDF API for the Earth System Grid Federation to enable PKI based authentication.


  • MyProxyClient: Python implementation of the client interface to the MyProxy Credential Management Service
