A Case for Atmospheric Transmittance: Solar Energy Prediction in Wireless Sensor Nodes
(2018)2018 IEEE International Conference on Internet of Things (iThings) and IEEE Green Computing and Communications (GreenCom) and IEEE Cyber, Physical and Social Computing (CPSCom) and IEEE Smart Data (SmartData)In this paper, we propose four novel schemes for solar energy prediction in wireless sensor nodes. Two of the schemes (WCMA-T and ProEnergy-T) are extensions of stateof-the-art schemes, while the remaining schemes (EWMA-T and Delta-T) are new. The proposed strategies leverage the extraterrestrial solar model [5] to get better prediction accuracy compared to state-of-the-art. We restrict our scope to schemes that only employ local information. ...Conference Paper -

Frequency Scaling as a Security Threat on Multicore Systems
(2018)IEEE Transactions on Computer-Aided Design of Integrated Circuits and SystemsMost modern processors use Dynamic Voltage and Frequency Scaling (DVFS) for power management. DVFS allows to optimize power consumption by scaling voltage and frequency depending on performance demand. Previous research has indicated that this frequency scaling might pose a security threat in the form of a covert channel, which could leak sensitive information. However, an analysis able to determine whether DVFS is a serious security issue ...Conference Paper -
The security risks of power measurements in multicores
(2018)Proceedings of the 33rd Annual ACM Symposium on Applied ComputingTwo of the main goals of power management in modern multicore processors are reducing the average power dissipation and delivering the maximum performance up to the physical limits of the system, when demanded. To achieve these goals, hardware manufacturers and operating system providers include sophisticated power and performance management systems, which require detailed information about the current processor state. For example, Intel ...Conference Paper
