Hacker attacks that involve stimulating voltage variations in an integrated circuit package are detected by deploying a network of elementary detectors distributed across the integrated circuit package. Each detector is positioned at a respective location within the package and is configured to generate an alarm signal in response to a voltage variation occurring at that specific location. The elementary detectors include a first component and a second component (such as flip-flops) with respective outputs configured to be set to complementary binary levels. Logic circuitry is coupled to the outputs of the first and second components and is designed to generate an alarm signal when the outputs of the first and second components no longer exhibit complementary binary levels, indicating a hacker attack involving a localized voltage variation within the integrated circuit package.

This invention belongs to the field of wind power system control technology and discloses a wind power system control method and controller to cope with DoS network attacks. It constructs a novel adaptive event triggering mechanism algorithm with memory characteristics. When a hacker launches a DoS attack on an interconnected wind power system through the communication network, the controller signal is not updated, and the communication triggering mechanism does not generate a new trigger moment. When the DoS attack interference signal is turned off, the value of the state variable changes, and the introduced adaptive threshold dynamically adjusts with the error. Simultaneously, the memory parameter introduces a time delay into the triggering mechanism. This invention proposes a new event triggering mechanism algorithm. The introduced adaptive threshold dynamically adjusts with the error, while the memory parameter introduces a time delay into the triggering mechanism. The combined effect of these two factors achieves system stability requirements while reducing data transmission and saving bandwidth. It has good adaptability and strong robustness and can be applied to various industrial applications.
