A serial number recognition method based on network message

Abstract

The invention discloses a serial number identification method based on a network message, which solves the problem of low identification accuracy of the serial number through periodical identification and serial number verification methods. According to the principle that the sequence number cycle is monotonic and the phenomenon that multiple message formats share the sequence number, the data after multiple sets are merged is periodically divided and judged to avoid the impact of multiple message formats sharing the sequence number and value drift and loss; It can realize the rapid identification of serial numbers with high accuracy, and verify the identified serial numbers to prevent the impact of numerical drift, multi-serial number mixing, and multi-message format shared serial numbers on the identification of serial numbers. Document classification and state machine inference provide guarantees.

Description

technical field [0001] The invention belongs to the technical field of serial number identification, relates to a network message-based serial number identification method, and is especially suitable for the serial number identification of protocol reverse. Background technique [0002] With the rapid development of network and application technology in recent years, network attacks have increased sharply, and network security issues have become increasingly prominent. In order to resist network attacks and ensure network and equipment security, many security personnel have designed and developed many security measures, such as intrusion detection, protocol reuse, and fuzz testing. These security measures rely on the detailed specification of the protocol. However, most of the protocols on the network are private protocols and lack corresponding specification documents. Therefore, an efficient and accurate reverse engineering method has become an urgent need for security pe...
