Potential Enabling Technologies for 7G Networks: Survey

Savo Glisic

Every new generation of mobile networks brings significant advances in two segments, enhancement of the network parameters within the legacy technologies and introduction of new technologies enabling new paradigms in designing the networks. In the first class of enhancements the effort is to increase data rates, improve energy efficiency, enhance connectivity, reduce data transmission latency etc. In the second class of innovations for 6G and 7G, we anticipate focus on optimum integration of advanced ML and AI in general, and quantum computing with the continuous interest in the satellite networks for optimal quantum key distribution . By introducing quantum technology 7G will be able to speed up computing processes in the net, enhance network security as well as to enable distributed QC, which is a new paradigm in computer sciences. Using advanced networks as a basic ingredient of inter system integration, here we focus only on the second segment of anticipated innovations in networking and present a survey of the subset of potential technology enablers for the above concept with special emphasis on the inter dependency of the solutions chosen in different segments of the network. In Section II, we present several anticipated 6G/7G (system of systems type) network optimization examples resulting in a new paradigm of network optimization indicating a need for quantum computing and quantum computing based optimization algorithms. In Section III we survey work on quantum cryptography and QKD.

Next-generation cryptographic techniques for robust network security

Himmat Rathore

Cryptography is a key enabling tool in digital security that is needed to protect information, secure communication, and ensure the integrity between connected networks. As cybersecurity threats continue to emerge constantly and, as evidenced by APTs, ransomware, and, later, quantum cyber threats, the need for stronger, more modern generations of cryptographic methods is more urgent than ever. Therefore, this paper seeks to discuss the emerging trends in the most recent cryptographic advancements including post quantum cryptography, homomorphic cryptography and security paradigms leveraging on blockchain system. These techniques are equally effective in correcting significant limitations of existing systems and in improving their overall efficiency and rates. The coursework points out the inherent weaknesses of traditional cryptographic solutions, such as the exposure to quantum computing threat models and their ability to address current and future security needs. Through a brief discussion of the theoretical background and practical implementations, this paper aims to assess the efficiency of the latest cryptographic technologies in strengthening network security measures. Research insights show that using third-generation cryptographic approaches is far more effective in protecting information from new risks. Besides, applying these methods in essential industries, including finance, healthcare, and IoT, supports the practical utilization of these methods. Based on the findings of this research, these innovations should be adopted to secure digital structure in a growing complex environment.
