Chip safety starting method and device, storage medium and terminal

Abstract

The invention relates to a chip safety starting method and device, a storage medium and a terminal. The method comprises the following steps: a starting instruction for a target chip is received, a memory initialization operation is executed, and in the memory initialization operation, the target chip stores a system file of a to-be-run program into a static storage area; whether the system file is stored in the static storage area or not is detected; when the system file is stored in the static storage area, whether a safety check permission is opened or not is detected; if the system file isopened, an encrypted signature is obtained from the system file; a pre-configured field in the system file is read to determine an encryption algorithm corresponding to the encrypted signature; and the encrypted signature is decrypted and the decrypted signature is verified, and if the verification is passed, the target chip is started to run the to-be-run program.

Description

Technical field [0001] This application relates to the security field of smart hardware, and in particular to a method, device, storage medium, and terminal for securely starting a chip. Background technique [0002] In recent years, with the rapid development of various sciences and technologies, some smart devices have appeared on the market, which are welcomed and loved by everyone, especially the emergence of Android (Android) system, which brings more smart hardware. For example, smart home appliances in smart homes, smart meters in buildings, surveillance cameras all over the street, and other IoT hardware that have been integrated into our lives may be far more than we thought. According to the statistics of chip research and development giant Arm, there are currently about 8 billion Internet of Things devices in the world, and it is expected that this number will exceed one trillion by 2035. In such a data-driven era, it is self-evident to ensure that these nearly trilli...

Problems solved by technology

[0004]In the prior art, the security verification of the memory chip of the smart hardware device is usually performed by using the RSA2048 decryption algorithm. However, in the prior art, the memory chip of the smart hardware device The security verification method, only supports one type of decryption algorithm, the scope of application is small, and the compatibility is poor
