Hash function digital signature
Hash-based cryptography is the generic term for constructions of cryptographic primitives based on the security of hash functions. It is of interest as a type of post-quantum cryptography. So far, hash-based cryptography is used to construct digital signatures schemes such as the Merkle signature scheme, zero knowledge and computationally integrity proofs, such as the zk-STARK proof system and range proofs over issued credentials via the HashWires protocol. Has… WebDec 16, 2024 · If the K used for a specific signature is public (which it'll have to be for the signature to be verified by someone holding the public key and the signature and nothing secret), then it is easy to find a second message M ′ such that CMAC ( M, K) = CMAC ( M ′, K); that is, the signature would also verify with that second message M ′.
