Abstract:In response to the current issue of weak security protection capabilities of control and protection hosts in hign voltage direct current (HVDC), this paper proposes a method based on trusted platform module (TPM) security chip, which uses the national secret algorithm SM2, SM3, SM4 to build the trusted root and use it for identity authentication. Through identity authentication and digital signature, the system overall design establishes a complete trusted chain from both hardware startup and software startup, and realizes the chain trusted boot for control and protection host from hardware startup, system load to system running. The experimental results show that the proposed scheme can well identify the risks of firmware tampering and identity forgery, realize the safe startup of the control and protection host, and improve the overall protection level of HVDC.
