12.1 Introduction
5G systems are the next major transition in the way of future mobile communications.
5G technology promises to provide higher bandwidth and lower latency. Unlike the
traditional mobile technologies, which are mainly meant for voice and data communications, 5G ensures to provide much more. 5G technology has the great potential to
enable services for new use cases and vertical industries, for example, in the healthcare,
transportation and smart homes. It provides opportunities for companies to build new
business models to deliver novel services to consumers in more improved and efficient
ways, as well as to increase their revenue. This rise in new business models, architecture
and technological changes in 5G will bring new challenges to the user’s privacy. The
privacy requirements is one of the crucial elements to consider in the discussion of 5G
technology as it is of utmost importance to balance the privacy requirements of users
with respect to the services offered.
The on-going mobile networks mainly consider four security aspects, that are;
authentication, integrity, confidentiality and availability. However, the privacy requirements are not at all (not only) taken into account from the infrastructure and but architecture’s perspective as well. As 5G will produce novel and critical applications, it is
therefore vital to consider the privacy characteristics from the architecture’s point of
view, such as observability, anonymity, unlinkability and pseudonymity. This will also
ensure the strong trust relationship of the consumer with mobile operators and with the
third parties, which are providing the various services. Also, not all privacy aspects can
be included while addressing the architecture of the network, due to the lawful and
privacy regulatory policies [1,14,15].
5G technology predicts the vision of “always available”, where the services are available
to users anytime and anywhere. This 24/7 connectivity with other devices may originate
a number of attacks such as impersonation, Denial‐of‐Services (DoS), and replay attacks
among others. 5G technology is also considered the key enabling technology for providing ubiquitous connectivity for smart objects. The immersive experiences, such as context
