Dynamic Multi-secret Sharing Scheme for Arbitrary Access Structure
摘要
Abstract
In order to realize verifiability and dynamic property of practical requirements for multi-secret sharing schemes with general access structures, this paper presents a dynamic multi-secret sharing scheme for arbitrary access structure, where each participant selects his own secret share, and sends it to the dealer without secure channel based on RSA cryptosystem. Meanwhile, on the basis of two-variable one-way function, pseudo secret share of each participant is calculated, and secret distributed algorithm and reconstructed algorithm are designed. Analysis result shows that in the reconstruction phase, each participant has only to present his pseudo-secret share to recover the secret without showing his real share, this scheme has the anti-fraud property, and it realizes the distribution of shares through public channel, which can reduce the cost of scheme.关键词
