Due to the globalization and capital costs of building and maintaining fabrication facilities, the number of fabs is shrinking every day and more vendors outsource the fabrication process to offshore fabrication facilities. Using such facilities makes the integrated circuits vulnerable to malicious alterations. These alterations are more commonly known as hardware Trojans and are usually created by...
Intrusion detection approaches have been presented which detect anomalous malware behavior at runtime. Most techniques involve software-based analysis which is too slow to support the tight timing constraints often imposed on embedded systems. We propose a hardware-based intrusion detection approach which does not alter the functional performance of the system. When using a real-time operating system,...
Modern microprocessor caches are often regarded as cool chip components that dissipate power uniformly. This research demonstrates that this uniformity is a misconception. Memory cell peripherals dissipate considerably higher power than the actual memory cell and this can result in up to 30°C of temperature difference between the warmest and the coolest part of the cache. To be effective and accurate,...
One of the critical security threats to computer systems is the execution of malware or malicious software. Several intrusion detection systems have been proposed which perform detection analysis in the software using the audit files generated by the operating system. Software-based solutions to this problem are relatively slow, so these techniques can be used forensically, but not in real-time to...
