基于变形的EIGamal的(t,n)门限秘密共享方案

(t,n) Threshold Secret Sharing Scheme Based on Deformative EIGamal

秘密共享是一种将秘密分割储存的密码技术,自1979年被提出来以后出现了许多的秘密共享方案。本文利用插值多项式将秘密值分割储存,并基于Schnorr签名方案提出了一种安全的(t,n)门限秘密共享方案,该方案能够验证正确的秘密份额并且有效地防止秘密份额被篡改.

Secret sharing is a secret segmentation stored password technology, there are a lot of secret sharing schemes since it was proposed in 1979. This paper segmented and stored the secret by using interpolation polynomial, then presented a （t,n） threshold secret sharing scheme based on Schnorr signature scheme. This scheme can verify correct the secret shares correctly, and effectively prevent tampering secret shares.
