AI Technical Summary

Technical Problem

After being connected to a network, energy storage battery management systems (BMS) are vulnerable to network attacks. Communication protocols are easily eavesdropped or tampered with, firmware is easily modified, and there is a lack of effective startup and software update verification mechanisms, resulting in low security.

Method used

A trusted execution environment (TEE) based on a hardware root of trust is adopted. By loading a pre-set root public key for digital signature and hash comparison verification, a trusted boot process is constructed. Encryption and authentication are performed in the trusted execution environment to ensure the integrity and authenticity of the firmware and data.

Benefits of technology

It achieves step-by-step trusted boot verification starting from the hardware root of trust, blocks the loading of unauthorized firmware, ensures the integrity and authenticity of the code throughout the device's lifecycle, prevents malicious code injection, and improves the security of the BMS.

Abstract

The application discloses a kind of energy storage battery management system's safe starting method and nonvolatile storage medium.Therein, the method includes: receiving the power-on request of energy storage battery management system;Based on the power-on request, load preset root public key and build trusted execution environment;Based on root public key, the digital signature of preset program is verified in trusted execution environment and the image corresponding to preset program is verified by hash comparison;In the case where the verification of digital signature and hash comparison verification are passed, load and execute preset program;Based on preset program, the kernel and drive module of operating system in energy storage battery management system are verified by signature and hash check in trusted execution environment using preset digital signature;Start energy storage battery management system.The application solves the technical problem that firmware is extremely easy to be tampered with, malicious code is implanted to cause low security due to the lack of start and software update verification mechanism of current energy storage system.
