  • Patent number: 9411009
    Abstract: Some embodiments described herein include a system that collects and learns reference side-channel normal activity, process it to reveal key features, compares subsequent collected data and processed data for anomalous behavior, and reports such behavior to a management center where this information is displayed and predefine actions can be executed when anomalous behavior is observed. In some instances, a physical side channel (e.g. and indirect measure of program execution such as power consumption or electromagnetic emissions and other physical signals) can be used to assess the execution status in a processor or digital circuit using an external monitor and detect, with extreme accuracy, when an unauthorized execution has managed to disrupt the normal operation of a target system (e.g., a computer system, etc.).

  • Publication number: 20150317475
    Abstract: A power fingerprinting system is adopted for assessing integrity of a target computer-based system. In one implementation, the power fingerprinting system may receive, at a first module, side-channel information of a first target component of a system, the first module being collocated with the first target component; obtain a power fingerprint for the first target component based on the side-channel information for the first target component, the power fingerprint for the first target component representing a plurality of execution statuses of the first target component; receive, at a second module, side-channel information of a second target component of the system, the second module being collocated with the second target component, the power fingerprint for the second target component representing a plurality of execution statuses of the second target component; and obtain a power fingerprint for the second target component based on the side-channel information for the second target component.

  • Publication number: 20120000662
    Abstract: Viscosity Differential Fracturing uses pneumatic and hydraulic fracturing techniques and a viscosity differential to achieve greater networking, higher amendment loading rates and more controlled propagation. Pneumatic fracturing is applied first in order to create a dense network of small fractures. This is followed by a hydraulic component using a viscosity adjusted fluid. This material can be injected into these fractures at a significant flow rate and extend/expand these fractures while filling them with the fluid. The significant advantage of VDF versus traditional hydraulic fracturing is that the density of fractures created by the initial gas process leads to an overall greater density of fractures emplaced within the subsurface coupled with the ability to emplace a greater mass of material (e.g. proppants, sand, reactants).
