    Abstract: A binary code similarity detection device performs a preprocessing operation of generating an assembly expression for the binary code by converting a machine language of an input binary code into an assembly language, extracting an assembly function or a command from the binary code converted to the assembly language, and detects a similarity to the assembly expression of a pre-stored binary code by inputting the assembly expression generated by the preprocessing operation to a trained model based on bidirectional encoder representations from transformers (BERT), and the trained model is generated by performing a pre-training step of causing the assembly expression to be understood and a fine-tuning step of inputting an assembly expression of a first binary code and an assembly expression of a second binary code to a pre-trained model and then fine-tuning the pre-trained model based on a similarity between the first binary code and the second binary code.

    Abstract: Various embodiments of the present disclosure relate to a system for analyzing an operation cause of a crash safety control logic of a vehicle an operation method thereof. The system for analyzing an operation cause of a crash safety control logic of a vehicle comprising: a collision safety model configured to receive a collision signal including signal values obtained from a plurality of collision detection sensors and to output a first collision type determination result corresponding to the collision signal according to a deep learning-based crash safety control logic; and an association analyzer configured to analyze an association between collision types included in the plurality of collision detection sensors and the first collision type determination result based on the collision signal and the first collision type determination result, wherein the association analyzer is configured to generate a noise signal by changing a first signal value of a first collision detection sensor among the signal values included in the collision signal, to obtain a second collision type determination result corresponding to the noise signal through the collision safety model, and to estimate an association between the first collision detection sensor and the collision types by comparing the first collision type determination result and the second collision type determination result.

    Abstract: A time-differenced carrier phase (TDCP) measurement value-based navigation system according to one embodiment of the present disclosure comprises: a satellite navigation system information reception unit for acquiring satellite navigation system information including a carrier phase measurement value; an initial position determination unit for determining an initial position of a target on the basis of the satellite navigation system information; a TDCP acquisition unit for acquiring a TDCP measurement value; a relative position determination unit for determining a relative position of the target on the basis of the TDCP measurement value; and an absolute position determination unit for determining an absolute position of the target by accumulating relative positions according to time of the initial position of the target. Therefore, time and expenses required for determining integer ambiguity can be reduced, and precise position of a cm-level error can be measured by using a low-cost satellite navigation system information receiver.
