“…This requires an appropriate infrastructure in terms of bandwidth, latency and throughput on the one side, and on the other side there are demands on the reliability of the AI in terms of Trusted AI and Trustworthy AI (Ma, et al, 2023). Although the quest for security and trust is perhaps as old as humanity itself -potential threats posed by strangers have always had to be recognised, mitigated and at best prevented-, trust must be developed, maintained, and reinforced (Lipps, et al, 2023). But with increasing globalisation and interconnection, combined with the ability to remotely access systems -it is no longer necessary to be in close proximity to access a system-, and with the rising importance of transmitted data in terms of confidentiality and privacy, the motivation for hackers and saboteurs is rising as well.…”

“…Nevertheless, on the path to replacing conventional mechanisms, it will play a decisive role how the methods of artificial intelligence and the distributed infrastructure will be treated. In the future, it will be more important to operate and learn on encrypted data (Smart, 2023) and to use methods such as Fully Homomorphic Encryption (FHE) (Sanon, et al, 2023) in order to take privacy aspects into account, as well.…”

“…Besides "traditional" methods such as Physically Unclonable Functions (PUFs) (Gassend, et al, 2002) -using properties of semiconductor devices and electronic circuits-, and Secret Key Generation (SKG) -using properties of the wireless radio channel-, these also include Human PUFsproperties of the human body; biometrics-. In particular, the so-called 6G-enabling technologies such as Wireless Optical Communication (Wei, et al, 2022), Reconfigurable Intelligent Surfaces (Lipps, et al, 2023) and AI, open up a wide range of possibilities for incorporating these methods into the security and authentication process.…”

Authentication and integrity are the prerequisites for trustworthy and secure communication. Without unambiguous knowledge of who is being interacted with, no confidential content can be exchanged, no (remote) access to systems and equipment can be granted, and no trust can be established. This situation is further exacerbated by an increasing interconnection and globalization towards a hyperconnected world. (Communication) Participants are no longer necessarily in close physical and social proximity and do not need to know each other, but can have their source/destination anywhere in the world. An authentication process is used to verify that someone -whether human or machine-, is in fact who she claims to be: The process thus includes a validation step to evaluate an assertion. However, systems differ in terms of their requirements, for instance with regard to the authentication options available, the time period required for re-authentication and the frequency of re-authentication, as well as the level of security to be achieved with authentication. The latter particularly with regard to the cost/benefit ratio of the application. Additionally, there are efforts to finally abolish traditional passwords, passphrases and pin codes and render them obsolete. In this work, technologies and methods for authentication beyond passwords and trustworthy authentication will be examined, particularly with regard to future communication infrastructures such as Beyond 5G and Sixth Generation (6G) wireless systems. Thereby, the impact of Artificial Intelligence (AI) methods, but also the relevance to Quantum Key Distribution (QKD) and Post Quantum Cryptography, as well as the use of 6G-enabling technologies like Reconfigurable Intelligent Surfaces (RISs), Wireless Optical Communication (WOC) and Physical Layer Security (PhySec), for example as additional factors of a multi-factor authentication process, will be considered, along with Body Area Networks (BANs) and the integration of the human body relying on biometrics. The various concepts are compared with regard to their requirements, limitations and possible applications in order to provide the user with an orientation as to which authentication method is conceivable and useful in which specific scenarios.
