Quantum Security for the Tactile Internet

Summary

The Tactile Internet aims at sending audiovisual and haptic signals (i.e. massive IoT data) to enable various families of use cases like human–machine cohabitation and remote control of robots. This requires stringent requirements in terms of latency, reliability, and security. Nevertheless, classical technologies are showing more and more of their intrinsic limitations to satisfy the required performance when paradigms like full network softwarization, in‐network intelligence and computing, and big data mining become part of the network design. Then, the interest for inherently different technologies/resources like quantum‐mechanical have been rising, since they provide new kind of resources for communication, computing, and security. However, the maturity of these technologies for direct implementation in future 6G networks and the Tactile Internet is still far. The objective of this chapter is to explain the main characteristics of quantum technologies, and paradigms in order to take advantage of their security benefits and enable the Tactile Internet efficiently and effectively. Some critical considerations are mentioned in order to highlight the main pros and cons of each solution.
