Abstract

The invention discloses a security chip upgrading method and a computer readable storage medium. The security chip upgrading method comprises the steps of obtaining first upgrading data according to firmware data; obtaining an access control address according to the firmware upgrading plaintext, and encrypting the firmware upgrading plaintext and the access control address to obtain second upgrading data; obtaining an upgrading data set according to the first upgrading data and the second upgrading data; performing proofreading processing on the firmware data to obtain a proofreading result, and receiving the upgrading data set according to the proofreading result; and performing data erasing and writing processing on firmware according to the upgrading data set. The firmware data can be proofread to obtain the proofread result, and the upgrade data set is received according to the proofread result to ensure that the received data set is legal data.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a method for upgrading a security chip and a computer-readable storage medium. Background technique [0002] In related technologies, the upgrade data is sent to the firmware in plain text, and the firmware is updated according to the plain text data to complete the firmware upgrade. [0003] However, sending the upgrade data to the firmware in plain text makes it easy to obtain and decipher the upgrade data halfway, and there is a greater risk of leaks. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes a security chip upgrade method, which can check the firmware data and obtain the check result, and receive the upgrade data set according to the check result, so as to ensure that the received data set is legal data. . [0005] The present inven...
