Abstract
The present invention relates to a reconfigurable switch forwarding engine parser capable of disabling hardware Trojans. The parser comprises a data preprocessing unit, several cascaded basic processing units and an extraction unit, wherein a key path of a basic processing unit of the first stage extracts and shifts a key bit keyword of a key, and sends a result to a data path of the current stage and a key path of the next stage; basic processing units of other stages carry out keyword extraction and shifting on a key frame and the data frame in sequence; and the extraction unit extracts the key frame and the data frame from a basic processing unit of the last stage, and forwards same to a subsequent packet processing part. The present invention can be widely applied to the design of the switch forwarding engine parser.
