On ASGS framework: general requirements and an example of implementation
: In the paper we propose general framework for Automatic Secret Generation and Sharing (ASGS) that should be independent of underlying secret sharing scheme. ASGS allows to preven...

Ideal Secret Sharing Schemes from Permutations
The work presents a new method for the design of ideal secret sharing. The method uses regular mappings that are well suited for construction of perfect secret sharing. The restri...

Analysis and Design of Multiple Threshold Changeable Secret Sharing Schemes
In a (r, n)-threshold secret sharing scheme, no group of (r - 1) colluding members can recover the secret value s. However, the number of colluders is likely to increase over time...

On the complexity of verifiable secret sharing and multiparty computation
We first study the problem of doing Verifiable Secret Sharing (VSS) information theoretically secure for a general access structure. We do it in the model where private channels b...

General Secure Multi-party Computation from any Linear Secret-Sharing Scheme
We show that verifiable secret sharing (VSS) and secure multi-party computation (MPC) among a set of n players can efficiently be based on any linear secret sharing scheme (LSSS) f...
