Abstract:
A method and an apparatus that generate a plurality of elements randomly as a split representation of an input used to provide an output data cryptographically representing an input data are described. The input may correspond to a result of a combination operation on the elements. Cryptographic operations may be performed on the input data and the elements to generate a plurality of data elements without providing data correlated with the key. The combination operation may be performed on the data elements for the output data.
