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."

Re:The graphic is a lie

Actual truth: Most of the CAs are Symantec, using multiple names to make it appear there is actually competition.
Graph: Huge lump of CAs making it look like they aren't all Symantec.
