PURPOSE:To obtain the scrambling method which is very difficult to decode by the 3rd party and has very high secrecy by selecting the correspondence between the scramble code and the scramble series apparently as 1:N. CONSTITUTION:As a pattern of the scramble series, 20 kinds of M series obtained by 10th and 11th generation polynomials, for example, are used. Codes not corresponding by 1:1 to the scramble series are included in the scramble codes. The codes signify the same scramble series as that by the preceding code. For example, a code 0A signifies the scramble series corresponding to a code 02 when the preceding code is 02. Thus, the codes correspond apparently to the scramble series 1:N. Then the relation of correspondence between the scramble codes and the scramble series cannot be known by individual check between the scramble codes and the scramble series. |
