摘要

This paper experimentally integrates an existing Kirchhoff–Law–Johnson–Noise (KLJN) physical key exchange scheme as a source of truly random keys for decentralized identifiers (DIDs). Web 3.0 is driven by secure keys, typically represented in hexadecimal, that are pseudo-randomly generated by an initialization vector and complex computational algorithms. We demonstrate that the statistical physical KLJN scheme eliminates the additional computational power by naturally generating physically random binary keys to drive the creation of DIDs that are appended to an Ethereum blockchain.
