Embodiment Construction
[0033] In order to describe the present invention more specifically, the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0034] The present invention is based on a dynamic intelligent contract vulnerability detection method combined with neural network and dynamic fuzzy testing. It mainly converts the intelligent contract into a contract execution flow diagram by means of an automatic extraction tool, further extracts the function execution path in the contract execution flow diagram, and uses the vector conversion tool Convert to vector form, build a feed-forward neural network model to detect vulnerabilities in smart contracts, and use SIF to instrument execution paths that may have vulnerabilities; Corresponding function execution paths; use forward-looking analysis methods to analyze different function execution paths, and assign different test weights; monitor functions...
