Abstract (in Japanese) (See Japanese page) 
(in English) In our previous study, a method for generating a random number sequence, which we call a mixture random number sequence, by mixing a pseudo-random number sequence with true random numbers was shown, and its degree of safety was analyzed. In this report, the mixture random sequence is applied to our secret sharing scheme. The analysis shows that the resultant secret sharing scheme keeps the characteristics of the mixture random number sequence; that is, it has a higher degree of safety than using a pseudo-random number sequence only, and the degree of safety gets higher as more bits of true random numbers are mixed.
