AI Technical Summary
In existing technologies, the accuracy of identifying the explicit and implicit fields of encrypted bitstream data is low, resulting in low accuracy in parsing unknown network protocols.
The algorithm employs a sliding window-based detection process, using multiple randomness detection algorithms to perform randomness detection on the bitstream data. The detection results determine the locations of the dense-to-light boundary and the light-to-dense boundary, and the binary expansion algorithm is combined to accurately identify the light-to-dense field.
This improves the accuracy of identifying explicit and implicit fields in encrypted bitstream data, providing more accurate basic data for subsequent network protocol analysis and enhancing the accuracy of network protocol parsing.
