Internet of Things security chip trusted mechanism

The invention discloses an Internet of Things security chip trusted mechanism, and relates to the technical field of Internet of Things security. The mechanism comprises the following steps: obtaininga physical unclonable function of a chip, and extracting a plurality of excitation corresponding pairs from the physical unclonable function; extracting a response part of the excitation corresponding pair as a first entropy value, and adding the first entropy value into an entropy pool; the Internet of Things equipment extracting communication protocol information in the communication process asa second entropy value and adding the second entropy value into an entropy pool; combining the first entropy value and the second entropy value in the entropy pool to obtain physical feature information; inputting the physical feature information into a fuzzy extractor, outputting auxiliary data P and a uniform random value R by the fuzzy extractor, and registering an identity by taking the auxiliary data P and the unifor
