People can only mentally handle a few trust anchors, so for SSL it goes: 1 User -> 2-3 browser makers -> 100's of CAs -> millions of websites The trust starts out narrowly funnelled and grows outwards as things get outsourced. For this it'd go 1 merchant -> 4-5 payment processing engines -> dozens of hardware manufacturers -> hundreds of thousands of devices --001a1133446031e17704fbfa20cb Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: quoted-printable

It's no different to the CA problem. P= eople can only mentally handle a few trust anchors, so for SSL it goes:

The trust starts out narrowly funnelled and grows outwa= rds as things get outsourced.
