A secret sharing scheme is a method for distributing a secret among several parties in such a way that only quali.ed subsets of the parties can reconstruct it and unquali.ed subsets receive no information about the secret. A multi-secret sharing scheme is the natural extension of a secret sharing scheme to the case in which many secrets need to be shared, each with respect to possibly di2erent ...

A multi-secret sharing scheme allows several secrets to be shared amongst a group of participants. In 2005, Shao and Cao developed a verifiable multi-secret sharing scheme where each participant’s share can be used several times which reduces the number of interactions between the dealer and the group members. In addition, some secrets may require a higher security level than others involving t...

C.-C. Yang, T.-Y. Chang, M.-S. Hwang [C.-C. Yang, T.-Y. Chang, M.-S. Hwang, A (t,n) multi-secret sharing scheme, Applied Mathematics and Computation 151 (2004) 483–490] proposed an efficient multi-secret sharing scheme based on a two-variable one-way function in 2004. But the scheme doesn't have the property of verification. A practical verifiable multi-secret sharing scheme, which is based on ...

A multi-secret sharing scheme, which is based on one-dimensional reversible cellular automata with memory, allowing any member of a set of participants to share a secret color image with the rest of participants is presented. Moreover, it is also explained that with this scheme, any participant is able to recover all the secret color images if and only if the whole set of participants pools the...

A multi{secret sharing scheme is a protocol to share a number of (arbitrarily related) secrets among a set of participants in such a way that only quali ed sets of participants can recover the secrets, whereas non-quali ed sets of participants might have partial information about them. In this paper we analyze the amount of randomness needed by multi{secret sharing schemes. Given an m-tuple of ...

The paper analyses the multiple assignment secret sharing scheme, presented at the GLOBECOM'87 Conference. It contains three technical comments and a contribution to extend the capabilities of Shamir scheme. First it is proved that the proposed multiple assignment secret sharing scheme is not perfect. In fact, the non-perfectness of the scheme is due to the non-perfectness of a certain type of ...
