Randomness in Multi-Secret Sharing Schemes
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 ...
متن کاملVisual Cryptography Schemes for Secret Image Sharing using GAS Algorithm
Visual Cryptography Schemes (VCS) is a method of image encryption used to hide the secret information in images. In the traditional VCS, the secret image is encrypted into n number of shares randomly and distributed to the n number of participates. The secret image can be recovered simply by stacking the shares without any complex computation involved. However previous approach suffers a securi...
متن کاملESSVCS: An Enriched Secret Sharing Visual Cryptography
Visual Cryptography (VC) is a powerful technique that combines the notions of perfect ciphers and secret sharing in cryptography with that of raster graphics. A binary image can be divided into shares that are able to be stacked together so as to approximately recover the original image. VC is a unique technique in the sense that the encrypted message can be decrypted directly by the Human Visu...
متن کاملOn the Dealer's Randomness Required in Secret Sharing Schemes
In this paper we provide upper and lower bounds on the randomness required by the dealer to set up a secret sharing scheme for innnite classes of access structures. Lower bounds are obtained using entropy arguments. Upper bounds derive from a decomposition construction based on combinatorial designs (in particular, t-(v; k;) designs). We prove a general result on the randomness needed to constr...
متن کاملPython Implementation of Visual Secret Sharing Schemes
Visual secret sharing schemes (VSS) represent an important concept of visual cryptography. They permit the sharing of a secret image between multiple participants so that only authorized groups can recover the secret. This paper considers the software implementation of some black-and-white secret images VSS in Python programming language. PIL (Python Imaging Library) provides strong image proce...
