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! Web10. Digital Signatures, hashes and MACs can do similar jobs. They allow someone sending a message to a check value along with the message. They allow someone receiving the message to verify that the message corresponds to the check value.
