Cryptographic Key Exchange: An Innovation Outlook
, Case Western Reserve UniversityAbstract
This article evaluates the innovation landscape facing the challenge of generating fresh shared randomness for cryptographic key exchange and various cyber security protocols. It discusses the main innovation thrust today, focused on quantum entanglement and on efficient engineering solutions to BB84, and its related alternatives. This innovation outlook highlights non-quantum solutions, and describes NEPSAR – a mechanical complexity based solution, which is applicable to any number of key sharing parties. Short-lived secret keys are also mentioned, as well as emerging innovation routes based on Richard Feynman’s observation: “there is plenty of room at the bottom,” extracting plenty of digital randomness from tiny amounts of matter, yielding very many measurable attributes (nanotechnology).
Note: The reported innovation outlook followed the procedure of the InnovationSP Platform (https://innovationSP.net).
