These platforms usually employ Priority-Preemptive NoCs (PP-NoCs), a widely used real-time on-chip interconnection structure that offers communication predictability. A deep analysis of the PP-NoC parameters and their impact on system security is required. Moreover, countermeasures that can protect the system while guaranteeing the real-time capabilities should be proposed and evaluated. To this end, this paper explores and evaluates the impact of the PP-NoCs parameters on system security; exploits PP-NoCs vulnerabilities and demonstrates for the first time two very powerful attacks; and proposes and integrates three new security countermeasures: RT-blinding, RT-masking, and RT-shielding. Results show that PP-NoCs are vulnerable to attacks and that is possible to uncover victim’s information with high accuracy (up to 96.19%). On the other hand, protection techniques were able to harden the system, effectively and efficiently mitigating the vulnerabilities while maintaining deterministic behavior. %G English %Z TC 10 %Z WG 10.5 %2 https://inria.hal.science/hal-03476604/document %2 https://inria.hal.science/hal-03476604/file/501403_1_En_10_Chapter.pdf %L hal-03476604 %U https://inria.hal.science/hal-03476604 %~ IFIP %~ IFIP-AICT %~ IFIP-TC %~ IFIP-WG %~ IFIP-VLSISOC %~ IFIP-TC10 %~ IFIP-WG10-5 %~ IFIP-AICT-586
