WebApr 7, 2024 · Hash-based signature schemes were first invented in the late 1970s by Leslie Lamport, and significantly improved by Ralph Merkle and others. For many years they were largely viewed as an interesting cryptographic backwater, mostly because they produce relatively large signatures (among other complications). WebAn alternative to (EC)DSA is the Schnoor signature scheme, which in its original form reduces the signature size from 4t-bit to 3t-bit for conjectures 2 t-bit security and at most 2 t/2 signatures per key. For example, at the 96-bit security level, a signature requires 36 bytes.

WebThese kinds of signatures take up 4s bits for a security of s bits. Example for RSA-PSS with message recovery: RSA modulus: 3072 bits hash: SHA-256 salt: 64 random bits Then, the signature of 3072 bits (384 bytes) stores a 256 bit hash (32 bytes), a 64 bit salt (8 bytes), and two fixed bytes (I think). That leaves room for up to 342 message bytes.
