A Dynamic Secret Sharing Scheme Based on Factorization
A dynamic (t, n)-threshold secret sharing scheme based on factorization is proposed in this paper. It has following properties: (1) the dealer can renew the secret key of the system without renewing the shadows of the participants; (2) when some participants’ shadows are revealed, they can be renewed without any effect on the others; (3) a new shadow can be generated for a new participant witho...
متن کاملNew Multistage Secret Sharing Scheme Based on Factorization Problem
A (t, n) secret sharing scheme [1, 2] allows a secret to be shared among n users in such a way that only t or more users can reconstruct the secret, but any t − 1 or less users have absolutely no information about the secret. One common drawback of almost all known secret sharing schemes is that they are one-time schemes. That is, once any t or more users reconstruct the secret by pooling their...
متن کاملSecurity Analysis of a Hash-Based Secret Sharing Scheme
Secret sharing schemes perform an important role in protecting se-cret by sharing it among multiple participants. In 1979, (t; n) threshold secret sharing schemes were proposed by Shamir and Blakley independently. In a (t; n) threshold secret sharing scheme a secret can be shared among n partic-ipants such that t or more participants can reconstruct the secret, but it can not be reconstructed b...
متن کاملOn the design and security of a lattice-based threshold secret sharing scheme
In this paper, we introduce a method of threshold secret sharing scheme (TSSS) in which secret reconstruction is based on Babai's nearest plane algorithm. In order to supply secure public channels for transmitting shares to parties, we need to ensure that there are no quantum threats to these channels. A solution to this problem can be utilization of lattice-based cryptosystems for these channe...
متن کاملDynamic Multi-Secret Sharing Scheme
Secret sharing schemes are very important techniques for the key management. To provide more efficient and flexible alternatives for the applications of secret sharing, this paper presents a dynamic multi-secret sharing scheme. A significant characteristic of the proposed scheme is that each participant has to keep only one master secret share which can be used to reconstruct different group se...
