Electronic Voting and Cryptography
Vortrag von Dr. Roland Wen
Datum: 18.03.13 Zeit: 11.00 - 12.00 Raum: Y27H28
E-voting is one of the most interesting and socially significant applications of cryptography. It is also a good example of the vital role of cryptography in protecting information privacy and integrity as technology pervades our everyday lives.In this talk I will give a gentle overview of cryptographic e-voting schemes and how they satisfy certain security properties. In particular I will focus on two properties:
1. verifiability, which enables voters and the general public to detect corruption (through flaws or malicious attacks) of their votes and the final election result;
2. receipt-freeness, which prevents voters from being coerced (through bribery or intimidation) to vote a particular way.
I will provide some brief, high-level examples to illustrate how receipt-free, verifiable e-voting schemes are constructed from cryptographic building blocks. I will also touch on the current challenges we face in deploying cryptographic e-voting systems in real-world elections.
