Abstract
In accordance with the present invention, there is provided a transformation pattern generating mechanism comprising: a key input section for inputting a key for encryption; a transformation pattern generating section for generating a transformation pattern for transformation of input data; and an output section for outputting the generated transformation pattern; wherein, when a number sequence corresponding to a predetermined transformation pattern is input as the key to the key input section, said transformation pattern generating section generates and outputs the predetermined transformation pattern corresponding to the number sequence.
