ABSTRACT:
Input data is split by a splitting part into a plurality of block data having an equal data length to be processed through respective channels. Each channel data is subjected in a function operation part to a function operation in direct or indirect relation to all the other channel data to produce new channel data. Each channel data is subjected in a transform operation part to a transform operation to produce new channel data. All final channel data obtained after function and transform operations are combined by a combining part to obtain randomized data.
