What Does an Anubis Mailer Session Look Like?
% I contact the Anubis Mailer with my user agent; a secure
session is negotiated. All further communications this
session are conducted in the session key.
% I declare myself to be FOO.
% The Anubis Mailer looks up the public key of FOO from N key
servers, where N is a small random number.
! If it cannot get an answer from N different key servers,
it will inform you of this and only transmit ringer text
for the session.
! If the majority of key servers disagree about your key,
it will inform you of this and close the connection.
% The Anubis Mailer will grab a random piece of text from its text
store and encrypt a challenge to you in your public key + it's
private key. It will send the challenge to you along with its
public key of record.
! Periodically the Anubis Mailer will query key servers about
its own public key of record. If it finds key servers in
majority disagreement, it will notify everyone who connects
to it of this fact. At this point, a user could choose to
have his or her agent send only ringer messages and close
the session without meaningful information exchange.
% You decrypt the challenge, encrypt it in your private key + the
mailer's public key and send it back. The Anubis mailer compares
the two messages.
! If they are not identical, the mailer will inform you of
this and only ringer text will be transmitted for this
session. The mailer may also generate a message for FOO,
informing FOO that a key spoofing attempt has taken place.
% At this point, your identity is confirmed with the Anubis Mailer for
this session. You may:
% Transmit outbound messages for anonymous remail.
% Collect messages bound for you.
% Transmit control strings embedded in ringer text:
! Ask that the IP address you are coming from be added
to the contact list.
! Set the frequency of the contacts
! Set the volume of the contacts
! Set your default pickup info for this session:
* this Anubis Mailer
* this Anubis Zone
* a particular newsgroup in alt.anubis.msgs
* a particular newsgroup outside alt.anubis
hierarchy (can be abused, use with care)
