The invention provides an RFID data acquisition method and device, and the method comprises the steps: enabling an RFID reading client to be connected with RFID equipment through a local HTTP service, receiving RFID tag information transmitted back by the RFID equipment through a callback interface, and carrying out the caching operation; the service system obtains RFID tag information through a local access address by using an HTTP interface, calls SSE service, controls opening or closing of message pushing of the SSE service through the HTTP interface, filters and encapsulates the cached RFID tag information through equipment coding, and performs rotation training on the SSE service through an asynchronous pushing thread so as to select a pushing mode of message pushing; and the service system reads the RFID tag array of the RFID reading client, carries out data check, and carries out data verification according to different service requirements. The data transmission and storage security can be effectively improved, the development cost is reduced, and the production efficiency is improved.

The invention discloses a software upgrading method, computing equipment and mining equipment, and the software upgrading method comprises the following steps: determining a target upgrading object according to a preset strategy in response to writing authorization passing; when a target upgrade package corresponding to the target upgrade object is determined from the external mobile storage device, opening a write-in permission for writing in the target upgrade package for the mobile storage device in the read-only management and control state; and performing software upgrading control according to the written target upgrading package. According to the technical scheme, write authorization verification can be carried out on the external mobile storage device so as to realize access supervision on the mobile storage device, and read-only management and control can be carried out on the mobile storage device when the write authorization is passed; therefore, when the target upgrade object is subsequently determined and the target upgrade package corresponding to the target upgrade object is determined from the external mobile storage device, only the write-in permission for writing in the target upgrade package can be opened to ensure that all operations are carried out within an expected range, and the purpose of avoiding implantation of malicious codes is achieved.

The present application discloses an embedded device firmware, a firmware upgrade method and an apparatus, wherein the embedded device firmware divides the root file system partition into two, one is a miniRootfs partition, and the other is a rootfs partition; the miniRootfs partition takes up very little space and has only network and upgrade functions; once the full-function rootfs partition upgrade fails, the miniRootfs partition will be started for upgrade recovery; and the common modules of the miniRootfs partition and the rootfs partition are extracted to set a common baseLibs library partition. In this way, in the case of small memory, not only the functions of the embedded device are not reduced, but also flash space is saved, thereby reducing the production cost of the product, ensuring fast and safe firmware upgrades, and remedial measures can be implemented when problems occur in the firmware upgrade.

The invention discloses a remote OTA upgrading method and system based on distributed networking verification, and the method comprises the steps: obtaining the upgrading configuration information of a to-be-upgraded device in response to an upgrading request of the to-be-upgraded device; sending the upgrading request to a plurality of target request gateways and receiving gateway response data of each target request gateway; based on a data cross validation algorithm, according to the gateway response data, determining gateway credibility and gateway efficiency corresponding to each target request gateway; and according to the upgrade configuration information, the gateway credibility and the gateway efficiency, determining upgrade data transmission strategies corresponding to the at least two target request gateways, and executing the upgrade data transmission strategies. Therefore, OTA firmware upgrading can be more efficiently and safely carried out on the to-be-upgraded equipment, the risk caused by an unsafe gateway or data is reduced, and the service stability in a large-scale equipment upgrading scene is improved.

This application discloses a firmware upgrade system, method, storage medium, and embedded device for embedded devices. The firmware upgrade system includes a main control computer and multiple levels of control modules. The main control computer establishes a data transmission link with the first-level control module, and wired or wireless data transmission links are established between every two adjacent control modules. In response to a firmware upgrade request, the main control computer determines the target control module to be upgraded and distributes the firmware upgrade data level by level along the data transmission links from the main control computer to the target control module, enabling the target control module to perform a firmware upgrade based on the upgrade data. This system can achieve unified upgrades of control modules at all levels in a hybrid topology or independent upgrades of control modules at each level. Its topology and firmware distribution method can flexibly adapt to the firmware upgrade needs of various embedded devices, ensuring safe and reliable upgrades for embedded devices.

The invention discloses a cooperative hardware security terminal architecture based on a glass vacuum cavity, which comprises an independently arranged glass vacuum cavity security module, can cooperatively work with an existing terminal main processor, and realizes hardware-level security upgrade on the premise of not influencing original performance and use experience. The glass vacuum cavity adopts two selectable sealing processes, so that both mass production and flexibility are considered; and a national security level hardware security unit is integrated in the cavity to realize key storage and encrypted transmission. An end-cloud collaborative architecture is adopted, sensitive data are not stored locally, and the security module can realize physical transplantation. The method is high in compatibility, does not depend on an advanced process, is high in physical attack resistance, can be widely applied to various smart phones and high-security-level terminals, and has high practicability and market value.
