FIG. 3 is a flowchart illustrating a method for transmitting fuzzing data according to an embodiment of the present invention. FIG. 4 is a flowchart specifically illustrating an example of the step of setting a transmission rate, illustrated in FIG. 3. FIG. 5 and FIG. 6 are flowcharts specifically illustrating an example of the step of determining effectiveness, illustrated in FIG. 3. FIG. 7 is a flowchart specifically illustrating an example of the step of determining whether an operation is performed normally, illustrated in FIG. 3.

Referring to FIG. 3, in the method for transmitting fuzzing data according to an embodiment of the present invention, first, context information may be collected at step S210.

That is, at step S210, context information pertaining to the one-way fuzzing target device that uses a one-way protocol may be collected.

Here, at step S210, context information may be collected by monitoring the one-way fuzzing target system 10, the one-way-fuzzing-target-processing unit 11, and data transmission from the one-way-fuzzing-target-processing unit 11 to the target-counterpart-software-processing unit 21.

Here, at step S210, the target context information collection unit 110 may periodically transmit the collected context information to the target execution state determination unit 120.
