1. the key I receive is indeed the key that is served by upon2020.com (my site — I publish my pgp key there via http, so it’s a good example) 2. the key served by upon2020.com is the key the owner of the site intended to serve 3. the site is under the effective control of one Johannes Ernst 4. the Johannes Ernst that owns that site is indeed the Johannes Ernst I want to communicate with So there are several avenues of attack, only some of which can be mitigated with HTTPS. I choose to believe that I’m not a valuable target enough to attack my public key distribution, in particular because I still send the majority of my e-mail unencrypted :-) The more secure way of matching key to individual is to receive the key from the individual directly, e.g. in direct contact, or by (secure) introduction from a trusted third party.
Back to Don’s original question: it should also have the tools by which the site owner would like to interact with others. Today, unfortunately, that largely is limited to blogging, plus some ways for others to talk back (commenting, pingbacks etc.) Innovation required here. Cheers, Johannes. |
