1. A method, comprising: applying, by one or more configured processing devices, a bijective transformation function on secret data, generating transformed data; applying, by the one or more configured processing devices, a cryptographic calculation function on a set of data of an input data stream and the transformed data, generating a second data stream, the set of data of the input data stream comprising a plurality of data; and applying, by the one or more configured processing devices, an inverse transformation function on the second data stream, generating a results data stream, wherein the results data stream corresponds to a data stream that would have been generated by application of the cryptographic calculation function on the set of data of the input data stream and the secret data.
