| Abstract: | Security can only be guaranteed as long as the hardware and other key
parameters, including software components, secret keys etc, of a device remain genuine
and unmodified. Under this context, device authentication must be considered as a key
security issue, complementary and of equal importance to user authentication, in today’s
wireless and forthcoming ubiquitous realms. This paper classifies and analyses possible
major solutions proposed until now towards solving the device authentication issue. We
constructively argue on each solution presented examining its advantages and
disadvantages. A qualitative comparative analysis for the device authentication schemes
in question is also offered, probing its applicability for both infrastructure and ad-hoc
deployments. Inter-domain device authentication, where applicable, and users’ privacy as
a side-effect are investigated as well. |
