While civil society waits for 5G that is to bring dramatic improvement in data speed, connection density and application versatility, technical community is already looking forward to the future of 6G networks. Huge transformations are predicted with the introduction of 6G technology, where ultra-fast speed, extremely large and real-time connectivity together with real-time data processing will be the order of the day. But they come with unprecedented security and privacy issues that have to be solved to secure this revolutionary ecosystem. For 6G networks, the new application requirements for connectivity will be challenging to meet in terms of coverage of services, low latency, high data rate and the massive number of machine-to-machine connections that the newly proposed networks expect to support; hence, good secure frameworks will be expected. These frameworks should include the ability to incorporate enhanced form of encryption, secure form of user authentication and effective control of access to resources and data from new forms of cyber threats. Further, the novel form of 6G networks will entail uses of decentralized ledger technologies, quantum-safe communications and this calls for unique ways to guarantee data authenticity and user anonymity. It bears repeating that the implementation of AI and machine learning in these networks will enable the identification of probable security threats and subsequent security threat counteraction in real time. Also, the number and varieties of the use cases that are expected to be served by 6G, including self-driving cars, smart cities, and telemedicine and remote operations and control, will require strong security to protect data and regain users’ confidence. As researchers work in together with industry to explore the idea of 6G, there will be the need to ensure that the established network infrastructure is secure and can withstand any threat that may hamper the usage of this newest wireless connection.
