On the(t,n) secret sharing scheme based on buried channel
Lei Xu · Journal of Hefei University of Technology · 2010
By the analysis of the share secret scheme of(t,n) based on Elgamal,an improved secret sharing scheme based on buried channel is proposed in this paper.Firstly,the sender encrypts the cryptograph,calculates the value of the shadow by the Lagrange interpolation method,and signs and encrypts the cryptograph by buried channel.Then,the receiver solves the cryptograph by Lagrange interpolation,and restores the clear text by buried channel.The study shows that this mode can prevent forging attacks,and detect the cheat actions of verifiers efficiently.Meanwhile,it can reduce the communication consumptions of network.
