<ol style="list-style-type:lower-alpha">
 
<li> calculates the hash
 
<li> checks whether it is known/corresponds to a authorized user.
 
<li> if yes, signs the CSR
 
<li> sends a HTTP reply with the signed certificate.

The signed certificate is stored inside the javabrowser and will be offered as client side certificate upon opening a HTTPS connection.

Projects:

Grid middleware security

This is all kinds of different security related work done within the Nikhef grid-middleware security group. See for example

It also covers work on the Risk Assessment Team for the EGI Software Vulnerability Group.

User delegation in the CLARIN Metadata Infrastructure

This project was a joined project between CLARIN via the The Max Planck Institute for Psycholinguistics (MPI) and Nikhef and supported by BiG Grid. See e.g. the project pages

jGridstart

This is a Java webstart application to gently guide (new) Grid user in the process of obtaining their grid certificate. See e.g. project page for more information.

nl.nikhef.slcshttps

This project was a joined project between The Max Planck Institute for Psycholinguistics (MPI), SURFnet and Nikhef and supported by BiG Grid.

See the project page for details.
