Problems solved by technology

[0004] However, the complexity of the architecture and operation that requires remote management of the server makes it more difficult to implement BIOS security protection in the same way as the client. The core reason for the increased difficulty is that the server usually has multiple BIOS update mechanisms.

Abstract

The invention provides a BIOS (basic input / output system) updating method based on a service processor as a trustable update source and belongs to the technical field of safety of servers. The methodcomprises: using a client-controllable service processor as a trustable update source for BIOS update process, verifying a BIOS update image via an RTU (remote terminal unit), and if verification of the BIOS update image fails, not writing in a BIOS flash memory; if the verification of the BIOS update image succeeds, configuring a locking mechanism by the RTU, and writing the BIOS update image inthe BIOS flash memory. The service processor is used as the trustable update source for the BIOS update process, legality and completeness of a BIOS image file that a user uses in the process of updating BIOS from a client are ensured, BIOS update is safer for a server that comprises one or more service processors, safety of company servers is ensured, BIOS update efficiency is improved, and errorrate of the BIOS update process is decreased.

Description

technical field [0001] The invention relates to the technical field of server security, in particular to a BIOS update method based on a service processor as an updateable trust root. Background technique [0002] The uniqueness and privileges of BIOS in modern computer system architecture make it an important attack target of some viruses and Trojan horses, and unauthorized modification of BIOS firmware by malware poses a major threat to it. Malicious BIOS modifications can be part of a sophisticated, targeted attack on an organization—permanent denial of service or persistent malware. [0003] The authenticated update mechanism uses digital signatures to ensure the authenticity of the firmware update image. The update of firmware images using the authenticated update mechanism relies on a Root of Trust Update (RTU) containing a signature verification algorithm and a key store that includes the public key required to verify the signature on the firmware update image.
