Privacy-Enhanced Event Scheduling
![](../../images/event-3577-128x128.png)
Event schedulers, well-known from groupware and social software, typically share the problem that they disclose detailed availability patterns of their users. This talk distinguishes event scheduling from electronic voting and proposes a privacy-enhanced event scheduling scheme.
Based on superposed sending and Diffie-Hellman key agreement, it is designed to be efficient enough for practical implementations while requiring minimal trust in a central entity. Protocols to enable dynamic joining and leaving of participants are given as well as a Web 2.0 implementation is presented.
