Bill gives his annual review of what has transpired in the world of
cryptography over the past year, and shares some interesting stories
about cryptography in history. Afterward, we hold our annual keysigning


A key signing party is a get-together of people who use the PGP
encryption system with the purpose of allowing those people to sign each
others keys. Key signing parties serve to extend the web of trust to a
great degree. Key signing parties also serve as great opportunities to
discuss the political and social issues surrounding strong cryptography,
individual liberties, individual sovereignty, and even implementing
encryption technologies or perhaps future work on free encryption software.

The basic workflow of signing someone's key is as follows:

Verify that the person actually is who they claim to be;
Have them verify their key ID and fingerprint;
Sign their key;
Send the signed key back to them

At the meeting, we go through the first two steps. Each person who
preregistered their key will announce their presence and then read off
their key ID and fingerprint, so everyone can verify that their copy of
the list of keys is correct. Once we've run down the list, we line up,
and each of us examines everyone else's photo IDs to verify that they
are who they claim to be. After the meeting is over, each participant
can then retrieve the keys that they've personally verified, sign those
keys, and send the signed keys back to their respective owners.

In order to complete the keysigning in the allotted time, we follow a
formal procedure as seen in V. Alex Brennen's "GnuPG Keysigning Party
HOWTO", attached below. It is strongly advised that if you have not been
to a keysigning party before, you read this document. We're using the
List-based method for this keysigning party, and the keyserver at

It is essential that, before the meeting, you register on the signup
form listed in the attachments. You should bring at least one picture ID
with you. You must also bring your own printout of the report on that
page, so you can check off the names/keys of the people you have
personally verified.

The list will be printed on Wednesday afternoon, the day of the meeting;
be sure to register your key for the keysigning before that. The
official cutoff time is 3:00 pm.

On-Campus Free Parking (These parking lots are free after 5pm)

The Amherst Street/E51 parking lot is the best parking option. It
probably will have plenty of spaces. During the school year the lot
tends to be full, but tends to clear out after 6:30 or 7PM.

Due to the never-ending construction, Sloan's Hermann Garage is only
accessible via Main Street. It is a small garage without a gate, and
directly under the Sloan library.

All other MIT lots require permits after hours.

The closest public parking
is Kendall Center Green Garage, next to the Marriott Hotel. The entrance is
90 Broadway Street. For other parking options, see

All Cambridge parking meters use Passport by Phone:
This is active on all Cambridge metered parking spaces. Meters are free
after 8PM
