1. a kind of home gateway encrypted data communication method, it is characterised in that follow the steps below:

  • Step1 home gateways and main website, open agreement two parameters g, N;

    Step2 main websites generate a random number x, as the private cipher key controlled oneself, and calculate X=gxModN, X are as disclosed closeKey, X negates sends home gateway to for X1, X1 by network;

    Step3 home gateways are received after X1, and X1 is negated as X, and home gateway generates a random number y, privately owned as what is controlled oneselfKey, and calculate Y=gyModN, Y are as disclosed key, and Y negates sends main website to for Y1, Y1 by network, meanwhile, meterCalculate K2=XyModN=gxyModN as encrypting and decrypting private cipher key;

    Step4 main websites are received after Y1, and Y1 is negated as Y, calculates K1=YyModN=gxyModN, is used as the private of encrypting and decryptingThere is key, main website calculates K1 and sends home gateway to by network;

    Step5 home gateways receive K1, and sending K2 to main websites by network carries out legal checking.
