1. method of in the connection between first and second functional modules of electronic component, transmitting data in the mode of safety, described method is characterised in that it comprises following step:

  • -will by first module kThe message injection of bit (M0-M3) is encoded to has the constant Hamming weight wnThe code word of bit (C0-C5);

    -this n bit codewords is transferred to second module;

    -be different from when the Hamming weight of the n bit codewords that receives by second module wThe time, produce rub-out signal;

    And -in the code word that does not have to decode and received under the situation of rub-out signal;

    Described method is characterised in that;

    k, wWith nBe the integer that verification concerns below;
