[quote="jmdesp"]The way you say this somewhat implies the flaw is more or less in some detail of the model. But it's simply an unavoidable flaw of using a model with many CAs, each of which has equal capacities with the others. It means the number of points of failure increases linearly with the number of CAs. But it's easier said "we need to fix that" than done. If you limit the number of CAs, you're limiting the competition and creating some kind of oligopole between the few that you still allow. Or you need to say this model of commercial CAs is too fragile and create some kind of administrative solution ? But actually here it's a governmental CA that failed, not a commercial one. Maybe you can limit the extend of a failure by not making all CAs equal anymore, by saying some may only issue certificates with some restrictions ? Well in this case, it doesn't change things so much, nl users still need the update urgently. So really easier said than done.[/quote]
