Abstract
An embodiment of a method and apparatus for ciphering data. Data is provided for ciphering. The data is ciphered in a plurality of steps. For each step, determining an encoding for error detection of the data being processed within the step. Determining an output error detection encoding for the step. Processing data of the round to provide output error detection encoding. Then, verifying the encoding against a determined output error detection encoding. If the output error detection encoding is not the same as the determined error detection encoding, providing a signal indicating the presence of an error within the cipher process.
