Definition Edit

Keyless Signature Infrastructure (KSI) is

designed to provide scalable digital signature based authentication for electronic data, machines and humans. Unlike traditional approaches that depend on asymmetric key cryptography, KSI uses only hash-function cryptography, allowing verification to rely only on the security of hash-functions and the availability of a public ledger commonly referred to as a blockchain.[1]
