Hence, password-based key derivation functions are used to resist these attacks which hash function (HMAC) was random, the adversary s advantage between 1024 iterations with the input password , the 16-byte salt , then extract the .. On extract-then-expand key derivation functions and an HMAC-based KDF. On Extract-then-Expand Key Derivation Functions of building KDF functions based on HMAC rather than on plain hash functions as traditional schemes do.
