Quantum mechanics has come a long way since the discovery of the initial fundamentals in the early nineteenth century. The field of quantum computing has since emerged from physics, finding theoretical application in modern computation systems, including within cellular networks such as 5G. Although security and privacy were seriously considered during the 5G standardization process, quantum computers could, in fact, undermine the confidentiality and integrity of the most modern telecommunications networks, including 5G.
5G is opening up a whole new set of opportunities for connectivity. However, privacy and data security concerns are set to play a key role as new vendors and new technologies emerge to capitalize on 5G capabilities. This expansion, added to the significant architectural changes, and quantum in particular, will make for highly complex networks, exposing new vulnerabilities and greater risks as we move towards a Post-Quantum Crypto world.
While today’s market opportunity for 5G security currently lies in network security solutions targeted at telco operators, increasingly, this will be overshadowed by demand for software and service security, with the market expected to reach US$8.6 billion in revenues by 2027. A growing share of that will come from enterprise markets looking to secure specific applications (e.g., URLLC, MMTC) and configurations (e.g., network slices) and prepare their networks for Post-Quantum Crypto.
