EuroCrypt 2012

rump session sponsored by Good Technology

Rump session slides are now available.

The EuroCrypt 2011 Rump Session took place on the evening of Tuesday May 17th. Exactly 11 months later, on the evening of Tuesday April 17th its genuine successor, the Eurocrypt 2012 Rump Session will be held...

We need your help to keep the Rump Session fun and entertaining! If you have difficulty giving a serious talk without people falling off their chairs from laughter, or if have discovered some new spectacular insights in cryptology, the rump session might well be the place to present it. To request a talk slot at the Eurocrypt 2012 Rump Session, please follow the procedure outlined below. Note that the deadline for requesting a slot is Monday 16 April 2012, 23:59 GMT.

Some submissions may have to be rejected by the Rump Session Programme Committee (just consisting of Martijn Stam) because of time constraints; please remember that the Rump Session is meant for short and entertaining presentations. We are not going to accept any conference/meeting announcements or job adverts from Nigel since these types of announcements are now well served by the IACR's online Calendar of Events and Open Positions in Cryptology web pages. (and please do check out IACR's groovy new web design).

New this year will be an Android application (thanks to Stefan Tillich) to vote for the ``Best Presentation'' at the Rump Session. The winner gets a small prize, but more importantly eternal glory and a sollication to submit to the illustrious Journal of Craptology. A small (adapted) quote from the great Proximo for inspiration:

Listen to me. Learn from me. I was not the best because I talked quickly. I was the best because the crowd loved me. Win the crowd and you will win your award.

To avoid endless, dull and boring fussing around with opening and closing files or worse, uploading slides or changing laptops en plein public, there will be a single laptop with all the presentation slides glued together (similar to last year). If you plan to give a talk without slides, or if you don't have slides ready yet, please prepare and submit one slide stating your name and talk title. Online updates of slides for previous submissions will be accepted until noon on Tuesday. Updated slides will not be accepted on USB sticks or by email!!!

Submission will be using the IACR web submission system, with some tweaks since this is, after all, supposed to be a fun rump. You will be able to change these details up until noon on Tuesday. The site is


An Abstract must be used to submit the following information:

  • A brief summary (not for publication)
    • We have factored the internet.
    • I want to share Shamir's secret.
    • I have found whar a car, card, and chair have in common.
    • The Jocular Diffie Hellman (JDH) assumption suffices for nilpartite key agreement.
  • Explanation (kept strictly confidential, ahum) why the talk should be accepted for the Rump Session. The options here are:
    1. Chocolate: only good quality will do to bribe the Rump Session chair.
    2. Track record: my talks are always funny.
    3. Future BPA: this will get people talking for the foreseeable future.
    4. Sequel/Prequel: this talk ties in with a previous rump talk.
    5. Serious: this is just a neat result I felt like sharing.
    6. Also ran: this result keeps being rejected from conferences, you're my only hope.
  • Freshness of your result:
    1. Prophetic: I don't even know of this result.
    2. Hot from the wire: I haven't told anyone about it yet.
    3. Stewing: this result has been the focus of my attention for the past weeks, some buzz is already forming.
    4. Cooked: the result has already been submitted to or accepted by some major conference, but you don't want to wait to hear about it.
    5. Overcooked: the result has already appeared somewhere, but you might not have heard of it.
    6. Trite: this result keeps being rejected from conferences, you're my only hope!

The Category field must be used to specify how many minutes you require. If you require more than 7, you might have misunderstood the concepts of a Rump Session...
