A Method of Juggling Information Based on Winsock2 SPI Framework

Considering the problem of tampering or forging the operational application information of military information systems, an information-tampered approach based on Winsock2 SPI technology is proposed in this paper. According to design the communication interface of systems information transmission service. In order to realize the purpose of monitoring and capturing the transmission information, we redefine the function of receiving and sending data packet. Then tampering the intercepted information according to the predefine rule and sending information to the destination. This method will apply to intercept and tamper the transmission data packet of military application systems based on TCP and UDP protocol. At last, the rationality and validity of the proposed method are validated through simulation test.
