Abstract
With the approaching implementation of 6G wireless communication networks, there will be opportunities and problems that have never been seen before, notably in privacy and security. In an era of hyper-connected, intelligent, and data-driven communication, this abstract investigates the cutting-edge technologies set to strengthen the integrity of 6G networks and protect users' privacy. Innovative methods, such as homomorphic encryption, differential privacy, and secure multi-party computation, are being investigated to protect the privacy of users. These approaches make it possible to process data without compromising sensitive information, which is in line with the growing desire for technology that protects individuals' privacy. In addition, biometric authentication serves as the primary form of verification, offering an additional layer of identity verification that is both robust and tailored in comparison to traditional approaches. As a result of the fact that it is anticipated that 6G networks would make use of network slicing, security measures are dynamically altered through isolated slices to meet several different service requirements. Wireless transmissions can be made more secure by the utilization of modern beamforming and signal processing techniques, which are part of the physical layer security. Traditional trust assumptions are called into question by the paradigm of zero-trust security models, which advocates for continuous authentication and authorization. This chapter provides a glimpse into the disruptive technologies that are going to determine the landscape of privacy and security in 6G wireless communication networks. These developments are critically important in laying a foundation that is secure, trustworthy, and privacy-focused for the hyper-connected future of wireless communication. The old ways of trusting people are being reconsidered because of a new security approach called zero-trust. Biometric authentication has an extra layer of security and can be more personalized than traditional methods. This approach suggests always checking and allowing access to systems and data, instead of relying on trust. This story shows how new technologies are changing the way we keep things private and safe in 6G wireless networks. These advancements are the basis for a future that is safe, dependable, and focused on privacy in wireless communication.
