摘要： An integrated circuit (IC) includes first and second secure memory elements storing identical data and a memory management system that executes a memory operation on the first secure memory element and a control operation on the second secure memory element simultaneously. The control operation is associated with safety of the IC and is executed to enable error detection in the second secure memory element, fault injection for the second secure memory element, masking of a power profile associated with the memory operation, or a combination thereof. After the execution of the memory operation and the control operation, the memory management system copies the data of the first secure memory element to the second secure memory element to maintain sanity of the second secure memory element.

摘要： A first plurality of logic gates and a second plurality of logic gates may be associated with a symmetric configuration. A first output at a first value may be generated by the first plurality of logic gates based on a first portion of input signals. A second output may be generated by the second plurality of logic gates at the first value based on a second portion of the input signals. A subsequent first output at a particular value may be generated by the first plurality of logic gates based on a first portion of a second plurality of input signals and a subsequent second output maybe generated by the second plurality of logic gates based on a second portion of the second plurality of input signals. A value of the subsequent second output may be complementary to the particular value of the subsequent first output.

摘要： 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.).
