Abstract: Embodiments of the present invention provide a data processing system and a data processing method. An MMIO address of a data request is obtained, where data stored in a PCIe storage device can be directly obtained from the MMIO address, and according to the MMIO address, a network adapter can directly read the data from the PCIe storage device of the data processing system, and transmit the data to a second data processing system, or directly write the data received from the second data processing system into the PCIe storage device. Therefore, the processing system can implement transmitting data directly from the PCIe storage device to the network adapter without using memory. During data transmission between the two data processing systems, a usage ratio of a resource, such as memory and a CPU, is reduced, and efficiency of data transmission is improved

Abstract: Example data query methods, apparatuses, and computer-readable medium are provided. After receiving a data query request, a data processing system queries target data required by a user from second files with a smaller data amount instead of a first file with a larger data amount. The second files are specifically generated based on the first file. Both the first file and the second file may be files formed by aggregated data or files formed by original data that is not aggregated. Alternatively, the first file is a file formed by original data, and the second file is a file formed by aggregated data. When data is queried, the second file with the smaller data amount is traversed.

Abstract: The disclosure describes a security system, including a security element and a clock randomization processing unit. The clock randomization processing unit is configured to: receive a clock signal, randomly change arrangement of high-level steps or low-level steps in the clock signal, and provide a changed clock signal to the security element. The security system in an embodiment of the present invention first performs randomization processing on the clock signal before inputting the clock signal to the security element, and then inputs a randomized clock signal to the security element. The randomized clock signal causes a module inside the security element to work irregularly. Therefore, it is much more difficult to perform analysis in a side-channel attack, and a security capability of the security element is improved.
