Trust anchors for GENI aggregates

This page lists various trust anchors which GENI aggregates can use. There's a section for the authorities that the GPO recommends for all GENI aggregates, and a second section for authorities which some aggregates may want to trust in unusual circumstances.

A note on certificate types:

  • A self-signed SA certificate can be added to an aggregate's list of trusted certificates by itself --- it contains everything the aggregate needs in order to trust that slice authority
  • Trusting the self-signed CA certificate for the GENI clearinghouse should be all that is needed to complete the chain to the clearinghouse's trust root.
  • An SA certificate which was signed by a self-signed CA certificate requires the inclusion of both the SA and the CA certificates.

Recommended GENI slice authorities

As of May 2015, the GPO recommends that all GENI aggregates trust the following GENI slice authorities (aka "the GENI cert bundle"), allowing the users at those SAs to use resources at GENI racks, GENI backbone and regional networks, etc.

The table below includes links to the SA certificate file, or to both of the MA and CA certificates, for each trust anchor. You can also download the entire bundle as a compressed tar file Download. The md5sum for the .tar.gz file itself is b8643cb0a695ff0ce2c6683e1031d133.
