zero-knowledge proof (ZKP) : cryptographic system that functions as a useful tool to protect privacy
https://openstax.org/books/introduction-computer-science/pages/14-key-terms
Cyber refers to anything relating to computers or information technology. At the same time, cyber resources are cyber tools, platforms, and solutions that store, process, and manage data and other assets electronically and make them available via networks, including the policies and procedures for handling cyber.
https://openstax.org/books/introduction-computer-science/pages/14-summary
The qualities that comprise cyber resources include security, safety, performance, usability, reliability, and autonomy.
