As usual, there will be a rump session at Crypto '98. The rump session is intended to be an informal session in which participants give short presentations on recent results, work in progress, and other topics of interest to the crypto community (possibly including presentations that are not purely technical in nature). Stuart Haber will preside over this year's rump session, which will take place on Tuesday evening, August 25. Those wishing to give a talk at the rump session must submit a short abstract, no more than one page long, either to the program chair, Hugo Krawczyk, or to the rump session chair, Stuart Haber. Submissions may be made either by e-mail (at most one page of ASCII text to stuart@surety.com) before Friday, August 21, or in person at the conference before noon on Monday, August 24. Submissions should include a requested amount of time for the presentation, up to seven minutes. Depending on the submissions they receive, the chairs will select a program for the session.
