  • Patent number: 12259974
    Abstract: Embodiments of the present application provide a processing method and apparatus for defending against shared storage side channel attacks, an electronic device and a computer-readable storage medium, and relate to the technical field of computers. In the embodiment of the present application, first time information is acquired by a clock thread, and the first time information is obfuscated to obtain second time information; and, the second time information is transmitted to an attack thread by a clock thread. Since the second time information acquired by the attack thread is obfuscated, that is, the second time information is inaccurate, the attack thread cannot successfully complete a side channel attack when it performs side channel attacks based on the inaccurate time information, so that the system can be protected.

  • Patent number: 12259823
    Abstract: The present disclosure discloses a virtual memory management method and apparatus supporting physical addresses larger than virtual addresses. The method comprises steps of: determining a target virtual address corresponding to an instruction fetch address or a load storage address in any one of a user mode, a supervisor mode, or a machine mode; determining a target physical address corresponding to the target virtual address by accessing a virtual memory management unit, the virtual memory management unit being internally provided with page table entries that map virtual addresses to physical addresses, the bit width of the target virtual address being possibly less than or equal to that of the target physical address, particularly in a many-core application field; and finally, returning the target physical address to a corresponding instruction fetch unit or load memory unit, thereby ensuring the correctness and validity.

  • Patent number: 12252898
    Abstract: The present invention relates to a prefabricated infilled panel-frame structure capable of accommodating seismic-loading and seismic energy dissipation, and a construction method thereof, including a frame body, a prefabricated infilled panel group, a panel connector, and a disc spring assembly. During an earthquake, the present invention slides to dissipate energy only after the maximum starting sliding force is exceeded, thus providing the structure with a relatively high lateral stiffness prior to sliding. After an earthquake, the disc spring assembly of the present invention may provide a certain restoring force due to being compressed so as to reduce the residual displacement. Further, the present invention achieves the bidirectional deformation cooperation of the prefabricated infilled panel under earthquakes, so that the infilled panel may still achieve the function of seismic energy dissipation under the coupling action of in-plane and out-of-plane loads.

  • Publication number: 20250088021
    Abstract: A BMS sleep wake-up circuit and method, a BMS, and an electric device are provided. The BMS sleep wake-up circuit is provided with an enabling circuit. When a charging device is connected, in response to the charging device being plugged in, the enabling circuit generates an enabling level to wake up a BMS, and outputs a self-locking signal through a control circuit, so that a wake-up chip keeps the BMS awake. Additionally, under the condition that the charging device remains plugged in, after the self-locking signal is canceled, the wake-up chip is turned off, so that the BMS can enter a sleeping state.

  • Publication number: 20250079880
    Abstract: This application discloses a BMS sleep wake-up circuit and method, a BMS, and an electric device. The BMS sleep wake-up circuit is provided with an enabling circuit. When a charging device is plugged in, the wake-up chip can be enabled through a first enabling signal to activate to wake up a BMS, and a control circuit outputs a self-locking signal, so that the wake-up chip keeps waking up the BMS. Additionally, after being activated, a mode in which the wake-up chip is enabled to activate is changed to a mode in which the wake-up chip is enabled through a second enabling signal to activate to wake up the BMS, so that when the charging device remains plugged in, after the self-locking signal is canceled, the wake-up chip is turned off, allowing the BMS to enter a sleeping state.
