 	abstract = "The next generation of MultiProcessor Systems-on-Chip (MPSoC) will encompass
 hundreds of integrated processing elements into a single chip, with the promise of highthroughput,
 low latency and, preferably, low energy utilization. Due to the high communication
 parallelism required by several applications targeting MPSoC architectures, the
 Network-on-Chip (NoC) has been widely adopted as a reliable and scalable interconnection
 mechanism.
 The NoC design space should be explored to meet the demanding requirements
 of current applications. Among the parameters that define a NoC configuration, the routing
 algorithm has been employed to provide services such as fault tolerance, deadlock and
 livelock freedom, as well as Quality of Service (QoS). As the adoption and complexity of
 System-on-Chip (SoC) increases for embedded systems, the concern for data protection
 appears as a new design requirement.
 Currently, MPSoCs can be attacked by exploiting either hardware or software vulnerabilities,
 with the later responsible for 80% of the security incidents in embedded systems.
 Protection against software vulnerabilities can occur at (i) Application Level, by using
 techniques such as data encryption to avoid plain data transmissions between Intellectual
 Property (IP) modules; or (ii) Communication Level, inspecting or filtering elements at the
 interconnect fabric with communication monitors or firewalls, respectively. As such, a routing
 algorithm aware of security requirements could also offer protection utilizing trusted communication
 paths in the NoC, avoiding potential malicious elements in otherwise unsafe communication
 paths.
 The main contribution of this work is a NoC protection technique at communication
 level by adapting Segment-based Routing (SBR) and Region-based Routing (RBR) algorithms
 to consider system security requirements, characterized by security zones which are
 defined on the NoC according to the mapping of applications on IP modules. Evaluation of
 the proposed routing technique considers aspects such as the scalability of routing tables,
 the number of secure communication paths, and the impact of this technique on applications
 of the NASA Numerical Aerodynamic Simulation (NAS) Parallel Benchmark (NPB).",
