Abstract: A method of and apparatus for searching for a signature in a packet according to a signature location. The method may include extracting a sub-payload to be compared with a signature from a payload of a packet, generating an offset that is location information about a location of the sub-payload in the payload, generating a search key that includes the extracted sub-payload and the generated offset, and performing ternary content addressable memory (TCAM) matching to check if the generated search key matches a TCAM entry.

Abstract translation: 根据签名位置在分组中搜索签名的方法和装置。 该方法可以包括提取要与来自分组的有效载荷的签名进行比较的子有效载荷，生成作为有效负载中的子有效载荷的位置的位置信息的偏移量，生成包括提取的子数据的搜索关键字 -payload和生成的偏移量，并执行三元内容可寻址存储器（TCAM）匹配，以检查生成的搜索关键字是否与TCAM条目匹配。
