Ideal secret sharing schemes with multipartite access structures

IEE Proceedings - Communications, 2006
The concept of quasi-threshold multipartite access structures for secret sharing schemes is introduced. These access structures allow one distinguished class of participants to retain control over the reconstruction of the secret, while allowing flexibility over the quorum of participants from other classes. While ideal bipartite access structures have

Ideal and Computationally Perfect Secret Sharing Schemes for Generalized Access Structures

2014
A secret sharing scheme is proposed in this paper. The scheme is ideal and uses computationally perfect concept. It uses a one way function and realizes generalized access structure. The scheme is useful for non-ideal access structures. For example, Stinson [14] has identified eighteen possible non-isomorphic monotone access structures with four ...

Ideal Secure Multi-Secret Visual Cryptography Scheme with Ring Shares

2014
With visual cryptography in mind, the security property of a new scheme is always one of main concerns. However, the ideal security is not taken into account in some visual cryptography schemes sharing multiple secrets. In this paper, the security of a multi-secret visual cryptography scheme proposed by Feng et al. is analyzed.
