Abstract
A method to determine valid input sequences for an unknown binary program is provided. The method includes obtaining multiple input sequences, which each include two or more different inputs, for an unknown binary program. The inputs for the input sequences may be valid inputs for the unknown binary program. The method may further include executing an instrumented version of the unknown binary program separately for each input sequence. For each execution of the instrumented version of the unknown binary program, a set of execution traces may be generated by recording execution traces generated by the execution of the instrumented version of the unknown binary program. The method may further include comparing the sets of execution traces and determining which of the input sequences the unknown binary program accepts as valid based on the comparison of the sets of execution traces.
