They want to GAK all keys including signature keys. Now think, to whom in your life are you willing to grant unlimited power of attorney? Your spouse? Your lawyer? Your banker? Your employer? Your government?
Almost. Actually, they mention at one point that they don't want to GAK the signature keys, but it's almost an afterthought. The thing I find peculiar is that they wand GAK through access to private keys in a PKI, ala Micali or Banker's Trust, but the only keys which need to be in a PKI are signature keys -- ones even they admit should not be recovered. Can you spell "empty intersection", boys and girls? :) Mighty clever of the cryptographer who started them down this path. - Carl +--------------------------------------------------------------------------+ |Carl M.
