摘要

To overcome the problems of low efficiency and poor security in the process of digital forensics, a digital forensics method based on direct if sampling for 5G communication system is proposed. In this method, the modulation parameters of the communication signal are obtained by the feature extraction algorithm of the receiver's in pulse signal, and the ontology model of digital forensics is constructed based on the ontology theory: analyse the disk image and judge the file category according to the pattern feature recognition results of the radiation source signal in 5g communication system; determine the hash value and information entropy, and generate the key index; summarise the digital forensics results and generate the digital forensics report. The simulation results show that the data processing efficiency is over 25/Mbps, and the successful attack rate in the security performance test is 2.89.
