Abstract:
An embodiment of a method is disclosed for protecting sensitive data from discovery during an operation performed on input data with the sensitive data. This embodiment of the method includes performing the operation on a first quantity of random data with the sensitive data using a circuit arrangement before performing the operation with the sensitive data on the input data using the circuit arrangement. After performing the operation with the sensitive data on the first quantity of the random data, the operation is performed with the sensitive data on the input data using the circuit arrangement. After performing the operation with the sensitive data on the input data, the operation is performed with the sensitive data on a second quantity of random data using the circuit arrangement.
