Abstract

The embodiment of the invention provides a firmware verification method and device, a storage medium and an electronic device.The method comprises the steps that under the condition that it is determined that a server is started, a decryption public key of an encrypted trusted signature header is obtained, the trusted signature header is generated by a baseboard management controller (BMC), and the trusted signature header comprises a first firmware hash value of firmware of the BMC; decrypting the obtained trusted signature header by using a decryption public key to obtain a first firmware hash value; and verifying the firmware of the BMC based on a comparison result between the first firmware hash value and a second firmware hash value of the firmware of the BMC, the second firmware hash value being an unencrypted value. By means of the firmware verification method and device, the problem of firmware verification in the prior art is solved, and the effect of effectively verifying the firmware is achieved.

Description

technical field [0001] Embodiments of the present invention relate to the computer field, and in particular, relate to a firmware verification method and device, a storage medium, and an electronic device. Background technique [0002] Save the public key in the trusted hardware TPM or TCM, and then perform secure signature verification on the firmware through the TPM and TCM chips. An additional TPM or TCM chip firmware signature verification public key is required, which increases the hardware cost of the product. Moreover, it is necessary to adapt the external API interfaces of TPM and TCM, and it is necessary to reserve physical channels to connect to TPM and TCM chips. The technology is relatively immature, and development is difficult. Contents of the invention [0003] Embodiments of the present invention provide a method and device for verifying firmware, a storage medium, and an electronic device, so as to at least solve the problem of verifying firmware in the r...
