Fuzzy test method and system for network protocol of terminal in power distribution area, and computer readable storage medium

The invention discloses a power distribution area terminal network protocol fuzzy test method and system and a computer readable storage medium. The power distribution area terminal network protocol fuzzy test method comprises the following steps: capturing, collecting and preprocessing a data set; the RNN is used for learning request MQTT protocol messages which respond normally in the data set, a model is generated, and then a test case is generated through the model; performing variation on the head and the data unit of the test case, and splicing variation results of the head and the data unit together to form a varied test case; carrying out self-adaptive adjustment on the byte importance of the varied test case to obtain a standard test case; and sending the standard test case to a power distribution area terminal to execute a fuzzy test, monitoring abnormal information, analyzing and recording vulnerabilities, and feeding back a test result. According to the method, the semantics of the network protoco
