2results about How to "Security upgrade" patented technology

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.
