Title:
PROGRAM AND METHOD FOR PACKET ANALYSIS
Document Type and Number:
Japanese Patent JP2016096416
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a technique for improving packet detection accuracy on a message-by-message basis.SOLUTION: A computer performs the processing of: extracting a packet group transmitted in an identical connection on the basis of packet capture data transmitted between communication devices; identifying a first top packet candidate and a second top packet candidate transmitted in the identical connection, on the basis of a time difference of the capture timing of each packet included in the extracted packet group; calculating a message length from the packet length of the packet group which includes the first top packet candidate and is captured after the capture of the first top packet candidate and before the capture of the second top packet candidate; estimating, from the first top packet candidate, a position in which the message length of the message formed by the packet group is stored, on the basis of the calculated message length; and detecting a message formed by the extracted packet group according to the message length stored in the estimated position.SELECTED DRAWING: Figure 6
