  The fifth generation of the telecommunication networks (5G) established the
service-oriented paradigm on the mobile networks. In this new context, the 5G
Core component has become extremely flexible so, in addition to serving mobile
networks, it can also be used to connect devices from the so-called non-3GPP
networks, which contains technologies such as WiFi. The implementation of this
connectivity requires specific protocols to ensure authentication and
reliability. Given these characteristics and the possibility of convergence, it
is necessary to carefully choose the encryption algorithms and authentication
methods used by non-3GPP user equipment. In light of the above, this paper
highlights key findings resulting from an analysis on the subject conducted
through a test environment which could be used in the context of the Eduroam
federation.
