A Public Key Cryptographic Scheme
Zhonghua Wang · Journal of Anshan Normal University · 2008
This paper proposes a public key cryptographic scheme with(t,n) threshold decryption based on Shamir's secret sharing scheme and ElGamal's cryptosystem.In this scheme,any t of n participants of the receiver can cooperate to reconstruct the plain text,but any t-1or fewer have no access to any bit of the plain text.The security of the scheme is analyzed.
