DESCRIPTION:Prof. Diego F. Aranha\, Aarhus University\, Denmark\nAbstract\
 nThis talk presents a detailed and up-to-date security analysis of the vot
 ing software used in upcoming Brazilian elections by more than 140 million
  voters. It is mainly based on results obtained recently in a restricted h
 acking challenge organized by the Superior Electoral Court (SEC)\, the nat
 ional electoral authority. During the event\, multiple serious vulnerabili
 ties (hard-coded cryptographic keys and insufficient integrity checks\, am
 ong others) were detected in the voting software\, which when combined com
 promised the main security properties of the equipment\, namely ballot sec
 recy and software integrity. We trace the history of the vulnerabilities 
 to a previous security analysis\, providing some perspective about how the
  system evolved in the past 6 years. As far as we know\, this was the most
  in-depth compromise of an official large-scale voting system ever perform
 ed under such severely restricted conditions. Joint work with Pedro Y. S. 
 Barbosa\, Thiago N. C. Cardoso\, Caio Lüders and Paulo Matias.\n \nBiogr
 aphy\nDiego F. Aranha is an Assistant Professor in the Department of Engin
 eering at Aarhus University. He was previously an Assistant Professor at t

 rs). He holds a PhD degree in Computer Science from the University of Camp
 inas and has worked as a visiting PhD student for 1 year at the University
  of Waterloo. His professional experience is in Cryptography and Computer 
 Security\, with a special interest in the efficient implementation of cryp
 tographic algorithms and security analysis of real-world systems. He recei
