摘要

在可验证秘密共享(VSS)方案中，每个参与者都可以检查经销商或其他参与者的欺诈行为。本文构造了一种具有最强计算安全级别的VSS方案，并在标准模型中证明了其安全性。该方案不使用双线性配对和哈希函数，具有抗主动攻击的安全性。

Game-based security proofs for verifiable secret sharing schemes in the standard model

ABSTRACT In a verifiable secret sharing (VSS) scheme, each participant can check cheating by the dealer or the other participants. In this work, we construct a VSS scheme with the strongest level of computational security and prove its security in the standard model. This scheme is secure against active attack and does not use bilinear pairing and hash function.
