METHOD FOR COMMUNICATION BETWEEN MOBILE TERMINAL AND INFORMATION SECURITY DEVICE

摘要

Provided is a method for communication between a mobile terminal and an information security device, the method comprising: a mobile terminal uses M different downlink encoding modes for encoding detection data packets to form M encoded detection data packets, and transmits the encoded detection data packets to an information security device; the information security device decodes the encoded detection data packets to obtain X1 detection data packets, and acquires marking information of the X1 downlink encoding modes; the information security device encodes the response data packets to form N encoded response data packets, and transmits the encoded response data packets to the mobile terminal; the mobile terminal decodes the encoded response data packets to obtain Y1 response data packets, and acquires marking information of the Y1 uplink encoding modes and marking information of the X1 downlink encoding modes, and finally determines destination uplink encoding modes and destination downlink encoding modes. The method can prevent communication failures caused by decoding failures resulting from different encoding modes, thus improving communication efficiency.
