Re: [sidr] Keys and algorithms for Updates - feasibility analysis? (was Re: RPKI and private keys)

Hardware cryptoprocessors raise the issue of export licenses. They are
also expensive. There will have to be software alternatives.

If we want widespread adoption, there must be an option to "just turn
it on" without having to shell out a load of extra money and fill a
lot of forms.

Security usability means more than just a zero-marginal-cost software
implementation. It means easy setup of keys and certificates, and
probably the option of running in "advisory more" where verification
failures raise error messages but do not cause routes to fail. That
will enable ASes to try, watch, and gain the confidence to turn it on.

Who's looking at security usability?
