    • An apparatus and method for extracting signature candidates and optimizing a corresponding signature are provided. The apparatus includes a packet separator, a header parser, a traffic information generator, a substring extractor, and a signature candidate extractor. The packet separator separates a packet into a header and a payload. The header information parser parses the header information, and the traffic information generator generates traffic information. The substring extractor measures a frequency of appearing of a substring with a predetermined length in the separated payload for a constant observation period, and extracts a substring having a frequency higher than a predetermined setup value by updating the measured frequency information to a substring frequency table. The signature candidate extractor generates a signature by collecting the extracted substring information and the generated traffic information, updates a signature frequency table, and extracts a signature candidate with reference to information of the signature frequency table.
    • 提供了一种用于提取签名候选和优化对应签名的装置和方法。 该装置包括分组分离器,头解析器,交通信息发生器,子串提取器和签名候选提取器。 分组分离器将分组分离成报头和有效载荷。 标题信息解析器解析标题信息,并且交通信息生成器生成交通信息。 子串提取器测量在分离的有效载荷中具有预定长度的子串的出现频率用于恒定观察周期,并且通过将测量的频率信息更新为子串频率表来提取具有高于预定设置值的频率的子串。 签名候选提取器通过收集所提取的子字符串信息和生成的交通信息来生成签名,更新签名频率表,并且参考签名频率表的信息来提取签名候选。
