  The advancement of manufacturing technologies has enabled the integration of
more intellectual property (IP) cores on the same system-on-chip (SoC).
Scalable and high throughput on-chip communication architecture has become a
vital component in today's SoCs. Diverse technologies such as electrical,
wireless, optical, and hybrid are available for on-chip communication with
different architectures supporting them. Security of the on-chip communication
is crucial because exploiting any vulnerability would be a goldmine for an
attacker. In this survey, we provide a comprehensive review of threat models,
attacks, and countermeasures over diverse on-chip communication technologies as
well as sophisticated architectures.
