Bulletin boards (BB) are important cryptographic building blocks that, at their core, provide a broadcast channel with
memory. BBs are widely used within many security protocols, including secure multi-party computation protocols, e-voting systems, and electronic auctions. Even though the security of protocols crucially depends on the underlying BB, as also highlighted by recent works, the literature on constructing …
