EM Side-channel attack generic countermeasure cryptographic hardware
2018/6/25
The threat of side-channels is becoming increasingly prominent for resource-constrained internet-connected devices. While numerous power side-channel countermeasures have been proposed, a promising ap...
Repetitive transcranial magnetic stimulation over inferior frontal cortex impairs the suppression (but not expression) of action impulses during action conflict
Nerve stimulation cognitive function response inhibition functional imaging technology
