1. A method for packet scrambling communication between a transmitting side and a receiving side connected through a network, comprising the steps of:

  • scrambling original data at the transmitting side, by dividing the original data into a plurality of data-units, assembling packets by storing the data-units in the packets and attaching to the packets scrambled packet identifiers indicating a scrambled packet order so that the packets can be scrambled by being rearranged according to the scrambled packet identifiers, and transmitting the packets in the scrambled packet order according to the scrambled packet identifiers from the transmitting side to the network;

    descrambling the packets received from the network at the receiving side, by recovering data-unit order information indicating a descrambled order of the data-units from the scrambled packet identifiers, and reconstrucitng the original data from the data-units stored in the packets according to the data-unit order information.
