WebApr 7, 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! WebOur hash function here is to take each value mod 10. The table to the right shows the resulting hash table. We hash a series of values as we get them, so the first value we hash is the first value in the string of values, and the last value we hash is the last value in the string of values. 22 mod 10 = 2, so it goes in slot 2.
