The focus of this paper is to determine if a common operating system can satisfy all the basic requirements of IoT devices, taking into consideration the limited capability of IoT devices, high customization needs, and security requirements, and if a single operating system can achieve this or not.

The leap from 4G to 5G technology is set to revolutionize our digital lives with faster speeds, lower latency, and better connectivity. However, this advancement brings significant privacy concerns, particularly regarding location data. The 5G standard includes a Subscription Concealed Identifier (SUCI) to enhance privacy by hiding users' permanent identifiers. Yet, SUCI's optional nature and the need for SIM card updates hinder its widespread use. Additionally, 5G's advanced features like beamforming and network slicing, though useful for precision services, create new risks by enabling precise location tracking. This paper examines why SUCI alone cannot adequately protect location privacy in 5G networks. We analyze how 5G improvements impact privacy, reveal vulnerabilities in network slicing, and propose enhanced identity verification and security measures. Our study underscores the necessity for comprehensive privacy protections to mitigate the complex threats in the 5G era.

The focus of this paper is to analyze the changes in the security of pacemaker IoMT (Internet of Medical Things) When its uses 5G networks connections compared with 4G network connection. This study compares the thread model of both connections and assesses the risk mitigation when using the 5G. The research indicates that while 5G offers enhanced security features, the inherent vulnerabilities of pacemakers remain significant and require further hardware-level security improvements.
