Abstract：
The invention relates to a reconfigurable switch forwarding engine analyzer capable of destroying hardware Trojan. The analyzer comprises a data preprocessing unit, a plurality of cascaded basic processing units and an extraction unit; a key path of the basic processing unit of the first stage is used for extracting and shifting key bit keywords of a key, and sending a result to a data path of thecurrent stage and a key path of the next stage; the data path of the basic processing unit is used for extracting and shifting key fields of data frames, generating extracted field offsets of the basic processing unit of the next stage and field offsets of the current stage, and sending the field offsets, field identifiers and the shifted data frames to the basic processing unit of the next stageor the current stage; the basic processing units of other stages carry out key word extraction and shifting on key frames and the data frames in sequence; and the extraction unit carries out key frame and data frame extraction from the basic processing unit of the last stage and forwards the extracted key and data frames to a subsequent packet processing part. The analyzer can be widely applied to the design of the switch forwarding engine analyzer.
