Some CAs sacrificed security for profitability. Which was the reason I started the EV process. If the race to the bottom had continued the products we sold would have no value at all. Getting your root into a browser requires you to get a WebTrust audit against your CPS. The problem is that before EV there were no requirements for the CPS. So long as your process said 'I do absolutely nothing at all', you could get your WebTrust audit. Some of the browser providers impose other requirements, but none addressed the validation criteria until EV was created. http://technet.microsoft.com/en-us/library/cc751157.aspx The only thing that was holding the system together was the fact that the older browsers could not update their root stores. So new CAs could only get a start by paying to cross-certify with an existing root. And all the roots that were inserted pre-Web Trust had been required to provide a CPS that actually committed them to do something with at least some meaning. That is why it costs more to get your CA cross-signed by some roots than others, those that promised least can command the highest prices. At this stage there are far fewer older browsers due to natural attrition and the older roots timing out. And at the end of this year Microsoft is going to pull the 1024 bit roots from the program. That is a good thing from the crypto point of view but will eliminate the last vestiges of control in the DV market unless something is done. I would like to deploy DNSSEC for the same reasons that you give. The problem is that at the moment it runs straight into a buzz-saw of global international politics. That is in the process of being fixed.
