An Interactive Graph of the Certificate Authority Ecosystem

An anonymous reader writes "Researchers of the International Computer Science Institute in Berkeley have created an interactive diagram that shows root-CAs, their intermediates, the relationships between them and how many certificates have been signed by them. The graph was generated by passively monitoring the Internet uplinks of a number of (mostly) edu sites for SSL connections and their certificate Information. Among other things the graph shows that one GoDaddy intermediate signed more than 74,000 certificates and that a German CA uses more than 200 sub-CAs for administrative reasons."

Not bad, but...

they probably should have hired Randall of XKCD to actually do the graphics... Nobody does these sorts of visualizations as well as that. And I just didn't find the alt-text funny at all. :)
