Abstract
A system for performing a secure sequence of transformations of a data value, using encrypted representations of the data value is disclosed. The system includes a first transformer for applying a transformation to an input data value to obtain an obfuscated representation thereof. The obfuscated representation contains a redundancy that depends on an input variable. The system further includes a sequence of second transformer for applying a transformation to compute transformed obfuscated representations. The system also includes a fourth transformer for applying a transformation such that a last obfuscated transformed data is obtained. The system further includes a fifth transformer for applying a transformation that depends on the last obfuscated transformed data and the input data.
