An apparatus that assists foot movement includes a normally twisted plate configured to interact with the foot. The foot has a pronation axis, and the normally twisted plate is biased and configured to twist about a plate axis that substantially approximates the pronation axis in response to a load received from the foot during foot pronation. As the foot pronates, the plate twists to apply a non-linear force substantially about the plate axis.

The invention discloses an energy analysis and detection method for an SM2 decryption algorithm, including S1, inputting test data M, C and d , and collect the energy curve during SM2 operation, where M is the plaintext, and C is the d The ciphertext generated by the corresponding public key encryption; S2. Simultaneously scan the doubling point curve segment and the point plus curve segment in the multi-point operation on the energy curve to obtain the analysis result d' ; S3, judging the analysis result d' and private key d Whether the binary representation of is the same except for the lowest bit, if so, the SM2 decryption algorithm design is not safe, otherwise the SM2 decryption algorithm design is safe. Compared with the existing technology, this solution requires fewer energy curves, and does not need to manually perform attack detection bit by bit during the detection process. At the same time, it liberates the labor and energy of the detection personnel, improves the automation level of detection and analysis, and improves the efficiency of detection and analysis. , simplicity, flexibility, effectiveness, and correctness.

The invention discloses a system and a method for detecting arrangement confusion and inverted arrangement of cigarettes in a cigarette warehouse. The system comprises an image acquisition unit, a display, an image processing unit, a multichannel video signal controller and an alarm unit; both the display and the image processing unit are connected with the image acquisition unit; and both the multichannel video signal controller and the alarm unit are connected with the image processing unit. The method comprises the following steps of: carrying out gray processing on cigarette arrangement images acquired by the detection system. carrying out pixel statistics on each white connected domain in the images which are subjected to corrosion and expansion processing, and obtaining a pixel area value S; comparing the S with a cigarette end pixel area M in a cigarette image of cigarettes which are normally arranged; judging whether the cigarettes in the current image are abnormal; and timely triggering alarm. The integral system has a simple structure and is low in cost; the cigarette arrangement detection method on the basis of the system is simple and efficient; labor intensity of workers is reduced; detection efficiency is improved; and detection on invertedly arranged cigarettes fills up a gap of cigarette packaging equipment.
