  • Automatic reverse engineering of message formats from network traces
    Patent number: 7802009
    Abstract: A system for automatic inference of message formats from network packets is described. Each network message from a set of network messages is split into one or more tokens based on the types of bytes in the network messages. The set of network messages can then be classified into clusters based on token patterns. The network messages in each cluster can then be further sub-clustered recursively based on the message formats. Further, the messages with a similar message format across the sub-clusters can be merged into a cluster. The set of formatted clusters thus obtained correspond to a set of message formats that can be used further for protocol reverse engineering.
