1998 Atlanta Linux Showcase
PGP Key Signing.

The 1998 Atlanta Linux Showcase is including a key signing Birds-of-a-Feather (BOF) session to further introduce PGP keys to Web of Trust. Showcase attendees may meet others who wish to have their keys signed and can confirm owner identities via face-to-face protocols (e.g., checking driver's licences).

After confirming someone's identity and key fingerprint, you can then properly sign their keys, so that others may not have to perform this step before using that person's key, assuming the potential key user trusts you to certify keys. This helps in the efficiency of using public keys for various functions, since being able to know that a key really belongs to the indicated owner is important.

To help setup this session, I need to know (via E-mail will be fine) if you are interested in participating in this keysigning. To help speed things along at the session, I will collect the public keys of interested parties beforehand, and make them available on a keyring on my web server (path to be announced later at the show).

I will bring listings of the keys on that keyring, along with the key fingerprints of each. Each BOF attendee can then identify themselves to the other attendees, and verify the correct fingerprint for their own key (so that everyone can verify that the keyring does indeed have the correct key for that person). Each person on the list will do this in turn, until all keys owners have been positively identified (we may have to negotiate on what is "good" ID for certain cases), and all fingerprints are verified. After that is done, each attendee can pick up the keyring at their leisure and sign the key or keys that they wish to sign.

If desired, everyone can send the signed keys back to me; I will act as a clearinghouse, collect all the keys and signatures, and issue a final keyring which has all keys with all the signatures. I can also send the final collection to the public keyservers as well.

We will try to have a procedure available to take care of users who did not know about the BOF before coming to the the Showcase or otherwise couldn't send me a key beforehand. It may be more difficult to help these users get signatures on their keys.

Please let me know if you have any questions or comments. PGP keys should be mailed to pgpbof@ale.org. Questions or comments should be E-Mailed to mhw@wittsend.com. If you will put a Subject: of "Showcase Keysigning" in your message, that will help me process it appropriately.

Note regarding PGP 5.x/6.x Diffie-Hellman keys... At this time, we have not determined if the keysigning will be restricted to RSA keys only or if well will make some attempt to include D-H keys. Your feedback is important on this. Any keys (RSA or D-H) which are signed by D-H keys can not be used by PGP 2.x or earlier or by Viacrypt PGP. Optimally, everyone should use RSA keys to avoid compatibility problems. Use of D-H keys for signing other keys should be limited to only other D-H keys.


Thank you!
