Theory of Cryptography Conference

(unofficial page by Oded Goldreich)

You may want to visit the official TCC site.

As I announced in the business meeting of TCC'13, I am stepping down as chair and member of the steering committee of TCC, and also do not intend to attend future venues. The reason is that, in the last decade, my research interests and activities have been drifting away from cryptography. I still find cryptography very interesting, but I believe one cannot pursue all that one finds interesting: Painful choices to keep away from many interesting issues (due to limited personal resources) are inevitable.

A short statement of purpose (by Oded Goldreich, Dec. 2002)

The needs of the theoretical cryptography (TC) community are best understood in relation to the two communities between which it resides: the Theory of Computation (TOC) community and the Cryptography/Security community. All three communities have grown in volume in recent years. This increase in volume makes the hosting of TC by the existing TOC and Crypto conferences quite problematic. Furthermore, the perspectives of TOC and Crypto on TC do not necessarily fit the internal perspective of TC and the interests of TC. All these indicate a value in the establishment of an independent specialized conference. A dedicated conference not only provides opportunities for research dissemination and interaction, but helps shape the field, give it a recognizable identity, and communicate its message.

To be more specific, our view is that there is a fair number of good TC papers per year that cannot (and should not) fit into either CRYPTO or FOCS/STOC. Such papers are the "growing grounds" of an area, and it is important to provide them with a stage. (These papers cannot fit in the general conferences because they are too many in number and because their main contribution is inherent to TC and less relevant to the wider audiences. They may lead to works that are fit for presentation in the general conferences, but they themselves don't really fit there.) Thus, we believe that there is a real need for a TC conference.

Impressions from the 1st TCC (by Oded Goldreich, Feb. 2004)

My impression is that the 1st TCC was a great success. The program was very good (see more below), the attendance was even beyond our expectations (approximately 100 registered), and the atmosphere was great (full of excitement and energy).

I don't recall ever feeling this way (wrt atmosphere)! I think that this has to do with the highly uniform/homogeneous nature of the set of attendees. It was amazing to see how the entire audience is interested (at least at some level) in almost every talk and follows (at least partially) every talk. At least this was true wrt myself, and consequently I was quite exhausted... It was amazing to go around the lecture room and hear groups excitingly involved in discussions that I could easily understand and relate to. My feeling was that this conference provided a meeting place to a community (which never met by itself before) and that the meeting provided a forum for extensive interaction as well as contributed to the self-image of the community. All this seems to yield a burst of energy that is most likely to enhence the area.

The bottom-line is that I feel that my a priori feeling that this conference has been needed turned out to be a big understatement. Firstly, the submissions and the attendance (with many traveling from the west coast, Europe and even Japan!) speaks for itself (and asserts that this conference is really needed). Secondly, I am bewildered to the thought of what would have happened and has been happening for years when this conference did not exist. That is, if this conference had not existed then

Let me say a few words on the program. I found the program to be of very good quality. I could spot only two papers (out of 27 in the program) of which I thought that they should not have appeared in the program. (As you know, I'm quite critical...) In my opinion, all the rest are of quality that is at least as good as the average CRYPTO/EC quality, but of course most of these papers would not have been accepted to CRYPTO/EC because they'd be considered to lack practical applications. (I'd even say that I'm willing to bet that, although each of the 25 papers could have been accepted to CRYPTO/EC, provided it were among few "theory" submissions, it is the case that if TCC would not have existed then at least 20 of these papers would not have appeared anywhere!)

The scope and goal of TCC

The Theory of Cryptography Conference is dedicated to the dissemination of results in the area (i.e., Theory of Cryptography). The conference aims to provide a meeting place for researchers and be instrumental in shaping the identity of the Theory of Cryptography community.

The Theory of Cryptography deals with the paradigms, approaches and techniques used to conceptualize, define and provide solutions to natural cryptographic problems. More specifically, research in this area includes:

Submission must not substantially duplicate work that any of the authors has published elsewhere. The submission should contain a scholarly exposition of ideas, techniques, and results, including motivation and a clear comparison with related work. Fot further details, see the CFP.

TCC Steering Committee Members: Mihir Bellare, Ivan Damgard, Oded Goldreich (chair), Shafi Goldwasser, Johan Hastad, Russell Impagliazzo, Ueli Maurer, Silvio Micali, Moni Naor, and Tatsuaki Okamoto.
