Abstract(in English)	Shamir's polynomial interpolation scheme is a secret sharing scheme with univariate polynomial. In this study, we investigate the access structure of a secret sharing scheme with bivariate polynomial. In this case, the structure is not a threshold access structure, but in a class of general access structure. We characterize the access structure by constellation of the shares. In this manuscript, we reveal the access structure of secret sharing scheme with second-degree bivariate polynomial.
