Abstract
A method is disclosed for providing first data and a first secret key to a cipher processor for ciphering. The first data is ciphered in accordance with a first cipher process and the first secret key to provide output data. Before ciphering of the first data, extra data is inserted within the cipher processor for ciphering in accordance with at least a portion of said first cipher process. The extra data is inserted within a sequence of cipher processor operations for obfuscating the output data.
