Introduction

Sung Won Yi is a notable inventor based in Seoul, South Korea. He has made significant contributions to the field of network security through his innovative patents. With a total of 2 patents, his work focuses on enhancing the reliability of network attack signatures.

Latest Patents

One of his latest patents is titled "Method and apparatus for generating network attack signature." This invention provides a method capable of generating a signature with high reliability while minimizing the whitelist used to prevent false positives. The process involves separating an application header and application data to measure byte distributions from an input packet. By analyzing these distributions, the method generates an attack signature using substrings from the application data, while the application header serves as supporting information.

Another significant patent is "Apparatus and method for extracting signature candidates of attacking packets." This invention includes a packet separator, header parser, traffic information generator, substring extractor, and signature candidate extractor. The apparatus separates packets into headers and payloads, parses header information, and generates traffic information. It measures the frequency of substrings in the payload and extracts those with a frequency higher than a predetermined value, ultimately generating a signature candidate based on the collected information.
