1. A method for performing the transmission of private data between a first network node and a second network node of a public network, comprising the steps of:

  • installing a universal checker in the second network node;

    sending a format packet having a set of checker-polynomial coefficients from the first network node to the second network node;

    receiving and storing the set of the checker-polynomial coefficients in the universal checker of the second network node;

    generating a check data associated with the private data according to the set of the checker-polynomial coefficients in the first network node;

    sending a data packet including the private data and the check data from the first network node to the second network node; and

    verifying the check data by using the universal checker in the second network node for checking the correspondence between the private data and the check data.
