Post-Quantum Single Secret Leader Election

Dan Boneh

In a Single Secret Leader Election (SSLE), a group of participants aims to randomly choose one leader from the group, with the restriction that the identity of the leader will be known only to the chosen leader. At a later time, the elected leader should be able to publicly reveal their identity and prove that they have won the election. The election process itself should work properly even if many registered users are passive. Among the many applications of SSLEs, they have the potential to enable more efficient proof-of-stake-based cryptocurrencies. In this presentation, Dan Boneh (Stanford) surveys SSLEs, including some recent results on post-quantum constructions. Based on recent work with Aditi Pratap and Lior Rotem.
