Tangible Encryption: Extended Analysis Companion to DOI 10.5281/zenodo.19259339

Abstract

This document provides an extended analysis and applied systems perspective on Tangible Encryption, a framework that replaces the “secret zero” problem in secrets management with a token-based identity model. Expanding on the formal definition, this work explores architectural integration with existing systems such as HashiCorp Vault, Mozilla SOPS, and cloud key management services, detailing how non-fungible tokens (NFTs) can function as persistent, ownable roots of trust. The paper examines practical implementation pathways, including hybrid encryption workflows, on-chain and off-chain verification models, and system design considerations for real-world deployment. It further contextualizes Tangible Encryption within AI-driven environments, addressing use cases such as machine learning model provenance, secure data sharing, and autonomous agent authentication across organizational boundaries. This work complements the formal analysis (DOI: 10.5281/zenodo.19259339) by providing expanded context, integration strategies, and operational considerations, offering a systems-level view of how identity-bound cryptographic tokens can unify authentication, access control, and auditability.
