Hey! :o

I am taking the course cryptography this semester and I will have a presentation at the end of the semester.

Could you give me some information about the following topics:
- An electronic voting system
- Lattices and lattice reduction

What are these topics about??

Which one would you recommend me??

Hi mathmari,

I haven't studies any of these topics in detail, but from what I know both of these topics are tied to Homomorphic encryptions. For example the Paillier encryption scheme is used in electronic voting and lattice based cryptosystems took a new turn with the recent construction by Craig Gentry. This paper was the first fully homomorphic encryption scheme (which basically means it's homomorphic with respect to both addition and multiplication) and it uses a lattice based construction.
