Abstract

This application relates to a security protection system and method embedded in a chip-based control protection device. The system includes a secure boot module, a password service module, a secure boot secret key module, and a firmware certificate module. The password service module is used to store cryptographic algorithms, secure boot The secret key module is used to store the asymmetric key of the signed device firmware, the firmware certificate module is used to store the firmware certificate proving the legitimacy of the firmware; the secure boot module is used to use the cryptographic service module as the The stored asymmetric key and the firmware certificate stored in the firmware certificate module perform security measurement on the component to be loaded, and start the chip operating system after the security measurement passes. By using the cryptographic service module as the root of trust and securely starting the chip operating system, it can actively protect the information security of the power grid protection terminal and improve the network security of the power grid protection terminal.

Description

technical field [0001] The present application relates to the technical field of power grid equipment, in particular to a chip-based control and protection device embedded safety protection system and method. Background technique [0002] With a large number of terminal equipment and multiple users connected to the power grid, an open and interactive network environment has gradually been built. Under the open environment, multiple power end users interact with each other in terms of supply and demand, which will soon break the existing hierarchical and partitioned information security protection pattern of vertical encryption and horizontal isolation of the power grid. [0003] Because the power system traditionally mainly relies on boundary isolation and dedicated system private protocols to ensure network security, power terminals generally developed based on general-purpose software and hardware platforms are easy to break through security barriers and cause serious attac...
