Web7 de abr. de 2024 · The first hash-based signature schemes was invented in 1979 by a mathematician named Leslie Lamport. Lamport observed that given only simple hash function — or really, a one-way function — it was possible to build an extremely powerful signature scheme. Powerful that is, provided that you only need to sign one message!
