EMI Pseudonymity Documentation

Functional Description

EMI Pseudonymity System is meant for providing its users a way to hide their true identity behind a pseudonymous identity. The term refers to a lesser degree of anonymity, as the relationships between the pseudonyms and the true identities can be revealed eg. in the cases of misuse. Users obtain pseudonymous identities from the Pseudonymity Service by using their existing Grid identity for authentication and authorization. The service registers the newly issued pseudonyms to the VO's attribute authority as aliases to the users' existing certificates. The service is accessed with a dedicated client tool.

The following graphic shows the interaction between the components of the service (the user is using pseudonymity client tool for accessing the pseudonymity service, voms-proxy-init for initializing the Grid proxy, and finally standard Grid tools for accessing the Grid):

The sequence for requesting pseudonymous credentials is illustrated in the following diagram (the AA client refers to the client tool used for obtaining the VO attributes, ie. voms-proxy-init in most cases):
