Segurança em Redes-em-Chip: Conceitos e Revisão do Estado da Arte

Networks-on-Chip (NoCs) aim at meeting the communication scalability required by Systems-on-Chip (SoCs), which are computing systems integrated into a single chip. As well as traditional distributed systems, a SoC and its network are susceptible to attacks to their security properties. This paper presents a survey that was conducted in order to identify the techniques that have been applied to provide security in NoC-based SoCs. The analyzed works were classified regarding the addressed attacks, the affected security properties, the adopted security mechanisms, and the components used to implement the proposed solutions. Concluding, the paper identifies the main attacks addressed by these works and the solutions most used to improve the network security.
