6G Security: Drivers and Needs
Executive Summary
Mobile networks are central to society's infrastructure, driving higher demands for security and reliability. As technology evolves and integrates the cyber and physical worlds more closely, 6G security must adopt a holistic approach that considers both communication and computation. Building on the security foundations of 5G, 6G networks will prioritize open standards, focusing on operational aspects. New technologies like immersive communication and zero-energy devices will necessitate updated threat analyses and innovative security solutions.
Introduction
6G networks represent a continuous evolution in mobile communications, following the successful deployment of 5G networks worldwide. These advancements offer transformative capabilities in connectivity and interaction, addressing the growing needs of individuals, industries, transportation, and healthcare. With the forecasted subscriber growth from over 1 billion in 2023 to over 5 billion by 2029, 5G is set to redefine how society interacts through mobile networks. As these demands expand, 6G networks will adapt to serve as comprehensive platforms, introducing new capabilities that bridge the cyber and physical realms.
The Drivers
Bridging Cyber and Physical Domains: The design of the 6G platform will incorporate and contribute to shifts in technology and societal paradigms, transitioning from distinct physical and cyber domains to a seamless cyber-physical continuum. This transformation necessitates a reevaluation of threats, risk assessments, and the development of new security solutions, especially in areas like immersive communication, extended reality, and artificial intelligence.
Technological Shifts and Paradigm Changes: As digital services increasingly become integral to daily life, the cyber domain is assimilating into the "real world," leading to a proliferation of connected devices and systems. This shift requires continuous threat analysis and the creation of security solutions that address data security and privacy concerns, particularly in emerging technologies like integrated sensing and communication.
Adaptation to Evolving Threat Landscape: The security landscape is dynamic, influenced by technological advancements and the integration of new use cases. As AI and automation become more prevalent, ensuring the reliability and security of AI functionalities becomes critical. This necessitates a broader perspective on security solutions that encompass data management, ownership, and privacy to balance utility and protection.
The Needs
To meet the demands of a global 6G network platform, security requirements must evolve alongside technological advancements. This includes addressing the challenges posed by new use cases, technologies, and the integration of devices that were not originally designed for connectivity. Ensuring the security of sensitive data, maintaining privacy, and managing the rapid changes in implementation technologies will require a comprehensive approach that integrates security throughout the development, deployment, and operation of the 6G platform.
Conclusion
Defining the security landscape for 6G networks involves recognizing the driving forces that shape its development and identifying key areas requiring attention. This includes considerations for the integration of cyber and physical domains, adaptation to a rapidly evolving threat landscape, and the need for a holistic security approach that encompasses both communication and computation. Addressing these challenges will be essential in realizing the full potential of 6G networks while safeguarding the integrity and privacy of users and data.
