Serial number identification method based on network messages

Abstract

The invention discloses a serial number identification method based on network messages. The method solves the problem with low accuracy for the identification of serial numbers through the periodical identification and serial number verification method. The method comprises the following steps: according to the monotonic principle a serial number presents periodically as well as the phenomenon that multiple message formats share a common serial number, conducting periodical division and determination to the data combined by a plurality of sets; and preventing multiple message formats from sharing a common serial number as well as from the influence of data value drifting and losing. The method of the invention can accomplish the rapid identification of serial numbers at high precision and can verify the identified serial numbers by preventing data value drifting and the mixing of a plurality of serial numbers as well as the influence on the serial number identification of the fact that a common serial number is shared by multiple message formats, therefore, ensuring the message classification and finite state machine deduction afterwards.

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...
