What a hash comparison, a digital signature and a Merkle inclusion proof each establish, what each leaves open, and how to combine them with Sphere10 Framework.
Read articleSee with a small Lamport-style model how signing twice with a one-time key exposes enough secrets to forge a signature, and what that means for stateful signing.
