Dynamic NoC buffer allocation for MPSoC timing side channel attack protection

Mathias Soeken

Multi-Processors Systems-on-Chip (MPSoCs), as a key technology enabler of the new computation paradigm Internet-of-Things (IoT), are exposed to attacks. Malicious applications can be downloaded at runtime to the MPSoC, infect IPs and open doors to perform ...
