Abstract

Event schedulers, well-known from groupware and social software, typicallyshare the problem that they disclose detailed availability patterns of theirusers.This paper distinguishes event scheduling from electronic voting andproposes a privacy-enhanced event scheduling scheme.Based on superposedsending and Diffie--Hellman key agreement, it is designed to be efficientenough for practical implementations while requiring minimal trust in a centralentity.Protocols to enable dynamic joining and leaving of participants aregiven.
