摘要：

We propose a password-protected secret sharing scheme which is provably secure without the random oracles. Three tools enable us to achieve this property: the IND-CCA secure threshold encryption scheme of Libert and Yung, the linear encryption scheme and the technique for constructing a simulation-sound non-interactive zero knowledge proof for any language in NP.
