A Practical and Provably Secure Scheme for Publicly Verifiable Secret Sharing and Its Applications
Abs t rac t . A publicly verifiable secret sharing (PVSS) scheme, named by Stadler in [Sta96], is a special VSS scheme in which anyone, not only the shareholders, can verify that the secret shares are correctly distributed. The property of public verifiability is what the first proposed VSS scheme [CGMA85] incorporated but later protocols [GMW87, Fe187, Ped911 failed to include. PVSS can provid...
متن کاملInformation-theoretically Secure Strong Verifiable Secret Sharing
In a (t,n) secret sharing scheme, a mutually trusted dealer divides a secret into n shares in such a way that any t or more than t shares can reconstruct the secret, but fewer than t shares cannot reconstruct the secret. When there is no mutually trusted dealer, a (n,t,n) secret sharing scheme can be used to set up a (t,n) secret sharing because each shareholder also acts as a dealer to decide ...
متن کاملUnconditionally Secure Verifiable Secret Sharing Scheme
Abstract A (t, n) secret sharing scheme permits a secret to be divided into n shares in such a way that any t or more than t shares can reconstruct the secret, but fewer than t shares cannot reconstruct the secret. Verifiable secret sharing (VSS) has been proposed to allow each shareholder to verify the validity of his own share, but not other shareholders' shares. In this paper, we propose an ...
متن کاملVerifiable Secret Sharing as Secure Computation
We present a stronger notion of veriiable secret sharing and exhibit a protocol implementing it. We show that our new notion is preferable to the old ones whenever veriiable secret sharing is used as a tool within larger protocols, rather than being a goal in itself.
متن کاملA practical verifiable multi-secret sharing scheme
C.-C. Yang, T.-Y. Chang, M.-S. Hwang [C.-C. Yang, T.-Y. Chang, M.-S. Hwang, A (t,n) multi-secret sharing scheme, Applied Mathematics and Computation 151 (2004) 483–490] proposed an efficient multi-secret sharing scheme based on a two-variable one-way function in 2004. But the scheme doesn't have the property of verification. A practical verifiable multi-secret sharing scheme, which is based on ...
