Verifiable Multi-secret Sharing Scheme on Linear Codes
摘要
Abstract
This paper proposes a verifiable multi-secret sharing scheme based on the Massy secret sharing scheme and RSA encryption algorithm. In the sharing phase, the shares of each participant are chosen by himself or herself and sub-secret is transmitted to the secret dealer by using public channel. In the recovering phase, designated combiner is allowed to check whether each participant provides the true value. Multi-secrets are dynamically renewed without re-distributing the participant's shares, the dealer only renew the values related to the renewed secrets in a public board. Compared with the former dynamic secret sharing schemes, this scheme has more interesting access structure.关键词
