Abstract:
1. A method for the authenticated transmission of a data set and/or of a program from a host having a host processor to a hardware security module i (HSM i ) comprising the following steps: a) at a system manufacturer's site, for i HSM b) at the system manufacturer's site, the first fixed code Fc c) at least one of the HSM d) at the production site, the HSM processor and the host processor are connected with each other by at least one interface; e) the host processor transmits to the HSM f) after reception of the response data sequence, the host processor couples the data set and/or the program to be transmitted with the third fixed code Fc g1) the HSM processor calculates, by means of the stored given algorithm, the second fixed code Fc g2) the HSM processor calculates by means of the stored given algorithm the second fixed code Fc h) upon agreement of the second fixed code Fc
