Abstract:
With the increasing popularity and adoption
of IoT technology, fog computing has been used as an
advancement to cloud computing. Although trust
management issues in cloud have been addressed,
there are still very few studies in a fog area. Trust is
needed for collaborating among fog nodes and trust
can further improve the reliability by assisting in
selecting the fog nodes to collaborate. To address
this issue, we present a provenance based trust
mechanism that traces the behavior of the process
among fog nodes. Our approach adopts the
completion rate and failure rate as the process
provenance in trust scores of computing workload,
especially obvious measures of trustworthiness.
Simulation results demonstrate that the proposed
system can effectively be used for collaboration in a
fog environment.
