B² Cryptography: A Symmetric, Hardware-Bound Authentication Architecture

Abstract

This white paper describes B² Cryptography, the authentication framework underlying the GoldKeyAlliance identity platform. B² replaces the structural assumptions of Public Key Infrastructure —certificate authorities, asymmetric key pairs, and computational hardness conjectures — with asymmetric-only, hardware-bound architecture where every security property is demonstrable ratherthan assumed.This document is intended for security architects and technical evaluators assessing B² forintegration into enterprise, education, healthcare, and regulated environments. It covers thearchitecture's design rationale, its cryptographic primitives and their composition, a comparativethreat model analysis against PKI-based authentication, and the offline authentication model fordisconnected environments.
