"We can end government censorship in a decade," Schmidt said during a speech in Washington. "The solution to government surveillance is to encrypt everything."

Setting aside the entertaining aspect of the source of said statement, I don't think encryption in and of itself is enough. Encryption performed by companies is useless, since we know by now that companies - US or otherwise - are more than eager to bend over backwards to please their governments.

What we need is encryption that we perform ourselves, so that neither governments nor companies are involved. I imagine some sort of box between your home network and the internet, that encrypts and decrypts everything, regardless of source or destination. This box obviously needs to run open source software, otherwise we'd be right back where we started.

Is something like that even possible?

Lennie,

Sounds like you've had a lot of experience navigating these muddied waters ;)

"- certs signing takes time, knowledge and effort to get done. Certs are actually already free (!) or cheap (10 euros). You don't pay for the cert. You pay for that time and effort to talk to a CA."

The thing is, they aren't all created equal. Many have bad support in browsers. And all the cheap CAs are of the automated variety, doing little more than contacting us via *insecure* email and http connections, pretty ironic right?

Another major problem with the CA model is that *everyone's* security gets reduced to the weakest CA in the browser, since that CA technically has the ability to forge signatures for any website whether they are even customers of the CA or not.


"Support for DNSSEC/DANE and SNI in browsers would help here."

Issues with complexity aside, I agree this is the way forward. It eliminates the security problems in relying on 3rd party CA's and also entitles everyone to certificates without having to buy them (everyone wins except for the CA's who loose big time).

It's great for academic theory, but in the real world ISPs, network equipment, and existing software are major hurdles with no easy answers. Look at initiatives like IPv6, jumbo packets, etc. In each case, we are all in firm agreement that the old standards are holding back technology, yet they're so deeply entrenched that we are barely any closer to deploying these things than we were 10 years ago.

I'm pretty convinced that the current internet will have to become completely unreliable before we will take migrations seriously.
