Method and system for using asymmetric cryptographic algorithm to prevent codes from being maliciously tampered

The invention relates to a method and system for using an asymmetric cryptographic algorithm to prevent codes from being maliciously tampered, and belongs to the technical field of encryption. The method comprises the following steps of 1, dividing original system software into two parts of a boot program and an application program; 2, modifying an original engineering entry address as other positions in flash; 3, burning the boot program and the application program into the flash of a main control chip separately; 4, judging whether system upgrading is needed or not. The method and system have the advantages that through encrypted protection of codes by an RSA algorithm, the codes can be effectively prevented from being maliciously tampered. By means of the method and system for using theasymmetric cryptographic algorithm to prevent the codes from being maliciously tampered, even if someone obtains the codes and the processing method of the system, he/she cannot conduct modification,and the set verification process cannot be skipped. The codes of the application program are encrypted, and an asymmetric algorithm is adopted for encryption, so that the integrity of the applicationprogram cannot be damaged.

Rotary-type prestressed tubular pile segmentation static load test method and device

The invention discloses a rotary-type prestressed tubular pile segmentation static load test method and device. The device consists of prestressed tubular piles in a segmentation manner, wherein the junction of two adjacent segmented tubular piles is connected with a loading steel plate and a sleeve, a loading device consists of a jack and loading fans on two ends of the jack (the jack is a rotary-type jack and also comprises a loading fan connected to the tail end of a pull rod on the bottom of the jack), the position of the loading device is changed by hoisting a steel pipe, the loading fan can pass through a through hole on the loading steel plate, the loading fan is staggered to the through groove after the rotation, and the jack applies load to the pile by virtue of the loading fan. When the test is carried out for a first segment and a second segment, the loading fan connected to the bottom of the pull rod of a coring-type jack contacts the loading steel plate, so that side friction resistance of the tubular pile below the test tubular pile is used as a static load counter-force, and the success of the test can be guaranteed. The static load counter-force is provided by the side friction resistance of the pile body, the device can be recycled for multiple times, and the test cost can be effectively saved.

glmm gene knock-out bacterial strain as well as preparation method and application in sieving mycobacterium tuberculosis phosphoglucomutase inhibitors

The invention discloses a glmM gene knock-out bacterial strain ML2009 (mycobacterium smegmatis), CGMCC (China General Microbiological Culture Collection Center) 3418, which is constructed by using phosphoglucomutase participating in the biosynthesis of key components in a mycobacterium tuberculosis cell wall. The bacterial strain ML2009 can be used as a cell model for sieving phosphoglucomutase inhibitors with high flux, be used for sieving effective phosphoglucomutase inhibitors from a combined compound library, traditional Chinese medicine and natural products to prepare tuberculosis-resisting medicaments with high medicine effects; and in addition, in the cells of a human body, the synthesis approach of UDP (Uridine Diphosphate)-acetyl glucosamine is different from that of mycobacterium tuberculosis, no phosphoglucomutase exists in the UDP-acetyl glucosamine, therefore, the reaction catalyzed by the mycobacterium tuberculosis phosphoglucomutase does not exist in the cells of the human body so that the tuberculosis-resisting medicaments developed by using the phosphoglucomutase as a target enzyme are harmless to the human body, and the defect that the traditional antibacterial medicament also kill normal cells is overcome.
