Secure Data Transmission in the Era of 6G: Challenges and Solutions

ABSTRACT


INTRODUCTION
Sixth-generation (6G) networks will soon be deployed, ushering in a new era of connection as a result of the quick development of wireless communication technology.From first-generation (1G) to the impending 6G, data speeds have increased exponentially, there is extremely minimal latency, and numerous devices are now connected.It has become clear how crucial it is to ensure safe data transmission as society depends more and more on this cutting-edge technology.
According to Shahraki et al. (2021) the 6G environment offers revolutionary capabilities like as data speeds surpassing 1 terabit per second, sub-millisecond latency, and the capacity to link an unprecedented number of devices per unit area.However, these amazing developments come with never-before-seen security difficulties.Terahertz (THz) frequency bands, massive multiple-input and multiple-output (MIMO) systems, edge computing, and artificial intelligence (AI)-driven architectures are a few of the ground-breaking technologies that will be incorporated into the transition from 5G to 6G (Chowdhury et al., 2020;Wang et al., 2020;Abdel et al., 2022).Despite the enormous potential of these breakthroughs, they also present fresh attack avenues and flaws that might be used by bad actors.
With each new generation, creative solutions are required to meet new dangers, since security has remained a constant problem in wireless communication (Banafaa et al., 2022).Due to the special features of 6G technology, security issues might soon reach previously unheard-of heights.Due to unique propagation properties, the use of THz frequencies for communication necessitates a reevaluation of security standards (Ruzomberka et al., 2023).Massive MIMO and beamforming, which improve network performance, may unintentionally result in the emergence of new areas of attack (Fonyi, 2020).Additionally, edge computing, a component of 6G design, poses issues with data integrity and privacy at the network's edge (Yazid et al., 2021).
The key place that AI plays in 6G networks brings both possibilities and dangers.While intelligent anomaly detection and predictive threat analysis are ways that AI might improve security, it can also be used by adversaries to plan intricate assaults (Jagatheesaperumal et al., 2021).The fine-grained data produced by 6G-enabled devices intensifies privacy concerns, calling for careful attention to legal and moral issues (Tariq et al., 2023).Creative Commons Attribution-ShareAlike 4.0 International License.

A thorough grasp of the vulnerabilities caused by the particular features of 6G is essential to overcoming these difficulties.The creation and use of reliable security measures that are flexible enough to respond to changing threats is equally important.As a result, this research begins an investigation into security issues and potential fixes for safe data transfer in the 6G future.
The goal of this study is to add to the growing body of knowledge on 6G security by analyzing the architecture's subtleties and spotting possible flaws.The research offers a path for safeguarding data transmission in 6G networks by outlining workable solutions based on cuttingedge cryptographic methods, AI-driven security measures, and physical layer security mechanisms (Porambage et al., 2021;Khan et al., 2022;Bhat et al., 2020).It emphasizes the value of multidisciplinary cooperation between academics, business leaders, and decision-makers to promote a comprehensive security strategy (Siala & Wang, 2022).
With these objectives in mind, our research aims to close the knowledge gap between the existing state of wireless communication security and the upcoming problems brought on by 6G technology.The research seeks to provide insights guiding the creation of adaptive security methods reducing possible risks by examining the security implications of 6G's core components.The research also looks at the legal and moral aspects of 6G security, emphasizing the necessity of balancing security requirements with user privacy rights (Karale, 2021).
The confluence of ground-breaking technologies necessitates a proactive security approach as society rushes into the 6G future.A strong data transmission infrastructure is required for the smooth integration of 6G into crucial industries (Mahmood et al., 2020).This study sets out on a quest to understand the security issues affecting 6G and provide creative fixes for shoring up its pillars.This work seeks to make a substantial contribution to the conversation on secure data transmission in the 6G era by careful component examination, vulnerability assessment, and ethical considerations.
