Title:
Non-distributable key-sharing protocol with particular emphasis on the Internet of Things
Authors: Mario Mastriani
Abstract:Quantum key distribution (QKD) constitutes the most widespread family of information preservation techniques in the context of Quantum Cryptography. However, these techniques must deal with a series of technological challenges that prevent their efficient implementation, in space, as well as in exclusively terrestrial configurations. Moreover, the current smallsat constellations of Low Earth Orbit (LEO with an altitude of approx. 500 km) added to other satellites in Medium Earth Orbit (MEO), and geostationary orbits (GEO), plus a large amount of space debris present around the planet, have become a serious obstacle for Astronomy. In this work, a classic alternative to QKD is presented, also based on a symmetric key, but with low cost, and high efficiency, which dispenses with all the implementation problems present in the QKD protocols and does not require the use of satellites, and which we will call non-distributable key sharing (NDKS). Due to its low cost,
simplicity of implementation, and high efficiency, NDKS is presented as an ideal solution to the problem of
cybersecurity on the Internet of Things (IoT), in general, and IoT-fog-clouds, in particular.
