DESCRIPTION:Professor Rolf Haenni\, Professor in Computer Science at the 
 Bern University of Applied Sciences (BFH) in Biel\nAbstract\nIn most democ
 racies in the world\, according to the “one person\, one vote” princip
 le\, citizens have equal voting rights in elections. This implies that all
  votes from eligible voters are tallied (at most one vote per voter)\, and
  that all votes from ineligible voters are discarded. In classical paper-b
 ased voting systems\, this property is achieved to a satisfiable degree by
  various procedural measures. In an online voting system\, guaranteeing a 
 correct election outcome is much harder. The generally accepted approach t
 oday is to design systems\, which allow independent third parties to verif
 y the correctness of the election result.\nFrom a cryptographic point of v
 iew\, designing verifiable voting systems is very challenging. The main pr
 oblem results from the intrinsic conflict between the requirement of unani
 mously identifying eligible voters while protecting their vote secrecy. Va
 rious cryptographic protocols exists to solve this problem\, but most of t
 hem only provide a protection against rather weak types of adversaries. St
 ronger adversaries may try to corrupt the voter’s machines by malware\, 
 to buy votes from voters\, or even to coerce voters to vote in a specific 
 way.\nThis talk will give an overview of the most challenging technical pr
 oblems related to online voting. Some existing cryptographic voting protoc
 ols will be discussed. Particular attention will be given to the protocol 
 proposal for the next-generation Internet voting system of the State of Ge
 neva.\n \nBiography\nRolf Haenni is a professor in Computer Science at th
 e Bern University of Applied Sciences (BFH) in Biel\, Switzerland. He is a
  member of the E-Voting Research Group\, which is part of the Research Ins
 titute for Security in the Information Society (RISIS). He received his Ph
 D degree in Computer Science in 1996 from the University of Fribourg in Sw
 itzerland. He has been affiliated to the University of Los Angeles\, the U
 niversity of Konstanz in Germany\, and the University of Bern in Switzerla
 nd. His research interests include cryptographic protocols\, secure electr
 onic voting\, privacy enhancing technologies\, trust management\, uncertai
 n reasoning\, probabilistic logics\, and graphical models.\n \n \n
