OK, I buy the problem, but until we do something about the totally non-anonymising properties of the 'net, revealing that I want the public key for some person seems to be quite minor - compared, for example, to revealing that I sent him email each time I do.

But you don't have to reveal that you sent him email. You can use stealthy communication. Stealthy communication is communication wherein not only is the content concealed from eavesdroppers by encryption, but information about who is communicating with whom, when, or if at all, is concealed, as well. The Internet can be used for stealthy communication. The basic idea is that each potential participant has ongoing traffic to and from a message pool which is propagated world-wide. When the participant has no live traffic to send, dummy traffic is sent instead. The dummy traffic is indistinguishable from the live traffic except by using decryption keys which are chosen by correspondents. The outbound traffic continues autonomously without interruption for months and years and is not correlated to the live traffic, so an observer without the keys cannot determine when or how much live communication is happening. Inbound cover traffic consists of taking a full feed of the message pool at all times without interruption. A Debian Linux package exists which enables stealthy email. It has been in everyday use for years, although not widely. Details on request. I am looking for someone to host it. Any volunteers? -- StealthMonger
