Blockchain as an Enabler for Zero-Trust Architectures
Abstract
From the lessons that can be learned so far in this book, the author justifies why a new strategy is required to refocus our perception and utilization of computerized capabilities in the future. Chapter 8 focuses on the advancement of the cyber security discipline by determining trust-less control-sets – a fourth dimension if you will, comprising blockchain technology. Blockchain has been implemented in fungible forms, such as public bitcoin and Ethereum, and in a non-fungible manner like private keyless signature infrastructure. It is the latter that is of particular interest, where proven implementations have the potential to demonstrably act as a verifiable trust anchor, embellishing cyber security controls in a number of critical areas to ensure (1) preservation of data integrity, (2) digital finger printing of IoT assets to prove the source of data is trustworthy, (3) validation of identity and access management mechanisms, and (4) software provenance in the supply chain for not only traditional code-bases but also AI algorithms.
