The invention provides a component
verification method and device for an
Internet of Things device and a readable storage medium, and the specific implementation scheme comprises the steps: reading device component information of an OTP
storage area after the power-on of a device component is completed, and carrying out the self-
verification based on the device component information, and obtaining a component self-
verification result; sending a corresponding equipment component starting state to a verification platform according to a component self-verification result; receiving an identification random number generated by the verification platform in response to the equipment component starting
normal state, and calling an internal private key to perform
digital signature on the identification random number to obtain a signature value; and sending the signature value and a built-in digital
certificate to a verification platform, so that the verification platform verifies whether the component of
the Internet of Things equipment is a trusted component or not. According to the scheme of the invention, a part credibility verification mechanism of
the Internet of Things equipment is provided, the part credibility of
the Internet of Things equipment is improved, in addition, the part self-verification is carried out by the
Internet of Things equipment, the second verification is carried out by the verification platform, and the safety intensity of equipment part verification is improved.
