Internet of Things trusted execution environment kernel fuzzy testing method and system based on state variable inference

The invention discloses an Internet of Things trusted execution environment kernel fuzzy testing method and system based on state variable inference, and belongs to the field of Internet of Things trusted execution environment kernel testing. The method comprises the following steps: constructing a test sample template file based on document analysis to assist a fuzzy test; feedback information collection is executed based on fuzzy testing of a hardware simulator; inferring a kernel state variable structural body member of the trusted execution environment of the Internet of Things by adopting an active test method; and integrating test sample code coverage information and system state information to score the fuzz test seeds, and preferably selecting high-score seeds to perform fuzz test. The internet of things trusted execution environment kernel fuzzy test method and system based on state variable inference can perform high-efficiency test on the internet of things trusted execution environment kernel. 本发明
