Abstract
Systems and methods are disclosed for parallel match processing of network packets to identify data for masking or other actions. In part, the disclosed embodiments receive packets and identify packet data, such as sensitive data, by rapid parallel matching of packet data being communicated in multi-byte wide data paths to match parameters in order to generate match vectors. The match vectors are then used to generate control vectors that are subsequently used by packet processing circuitry to perform desired actions for this packet data (e.g., mask data) and/or for related packets (e.g., drop packets). For example, data identified through the match processing can be masked, and control vectors can be mask control vectors applied to parallel multiplexers. In certain embodiments, the parallel data multiplexers are controlled by the mask control vectors to selectively output either original packet data or mask data that obscures original packet data.
