Secure systems and trustworthy access are major concerns in the development of Beyond 5G (B5G) and Sixth Generation (6G) wireless systems. Due to the increasing complexity of new communication systems and the interoperability of different vendors, it is mandatory to exclude the risk of unauthorized access by integrating security concepts from the very beginning. In recent approaches in the research of wireless systems, various specialized solutions are being explored. This includes the seamless integration of localization and sensing along with the development of wireless body near sensors into a universal communication system. The topic of Medical Digital Twins (MDTs) is one aspect that helps improve quality of life by using body-near sensors to monitor biomedical data. This aggregated information also can be used for the authentication of a specific user and to grant access to approved systems. Therefore in this work, a set of Key Performance Indicators (KPIs) is developed to evaluate different aspects in the field of biometric authentication systems. The indicators are identified in the combined study of biometric systems developed in previous works, highlighting both advantages and disadvantages for each proposed biometric method with respect to authentication. These different biometric approaches result in a possible Wireless Body Area Network (WBAN) which is evaluated by using the defined KPIs to identify potential synergistic effects in Multi-Factor Authentication-combinations.
