(t,n) threshold secret sharing scheme without SDC based on ECC
FU Mao-sheng, Bin Luo · Computer Engineering and Applications Journal · 2008
By means of Ellipse Curve Discrete Logarithm Problem(ECDLP),a (t,n) threshold secret sharing scheme based on ellipse curve cryptography is proposed in this paper.Systemic initialization,the private key and the public key are produced with- out SDC,the secret sharing matrix is built by the secret sharing value of each member's.At last a (t,n) threshold secret sharing scheme is realized by the matrix and Lagrange interpolation theorem.The scheme is security in theory and is suitable for the practice.
