This work proposes a secure Network-on-Chip (NoC) approach, which enforces the encapsulation of sensitive traffic inside the asymmetrical security zones while using minimal and non-minimal paths. The NoC routing guarantees that the sensitive traffic communicates only through trusted nodes, which belong to a security zone. As the shape of the zones may change during operation, the sensitive traffic...
Multi-Processors Systems-on-Chip (MPSoCs), as a key technology enabler of the new computation paradigm Internet-of-Things (IoT), are currently exposed to attacks. Malicious applications can be downloaded at runtime to the MPSoC, infecting IP-blocks connected to a Network-on-Chip (NoC) and opening doors to perform Timing Side Channel Attacks (TSCA). By monitoring the NoC traffic, an attacker is able...
Applications are spread into the computational resources of the Multi-processors Systems-on-Chip (MPSoCs) to enhance the performance. This approach forces the peer interaction of different IPs, turning vulnerable applications characterized by security requirements. Sensitive traffic can be protected by implementing security domains, whose aim is to wrap sensitive IPs. Networks-on-Chip can be enhanced...
In order to improve the performance, embedded applications are distributed on several IP cores of Multiprocessors Systems-on-Chip (MPSoCs). Such a strategy forces the peer interaction among the different computation components, which have to exchange data through the Networkson- Chip (NoC). For applications for which security is an important concern, data exchanged among the IPs must remain confidential...
