Abstract: In one embodiment, the method includes computing composite cryptographic data by executing a plurality of first cryptographic algorithms, wherein the composite cryptographic data are computed as a function of input data, wherein the plurality of first cryptographic algorithms are selected and/or the plurality of first cryptographic algorithms are combined according to a first control algorithm; computing results data using a receiver cryptosystem as a function of the composite cryptographic data by applying one or more of the second cryptographic algorithms, wherein the one or more second cryptographic algorithms are selected and/or combined according to a second control algorithm; and automatically executing a software and/or hardware function using the receiver cryptosystem according to the results data.
