Research and application based on A. Shamir's (t, n) threshold secret sharing scheme

Secret sharing is an important means to achieve confidential information security and data privacy. This essay is based on the A. Shamir's (t, n) threshold secret sharing scheme, combined with precise number complementary judgment matrix sorting algorithm, to establish a preferred method for the selected alternatives of the strategic decision scheme in the selection of t/n value, eventually solved the characteristics of the ambiguity in t/n value's selection. Finally, this paper proves the feasibility and validity of this method through the examples.
