We describe a novel approach for building a secure and fault tolerant data storage service in collaborative work environments, which uses perfect secret sharing schemes to store d...
A secret sharing schemefor the prohibited structure is a method of sharing a master key among a finite set of participants in such a way that only certain pre-specified subsetsof ...
Abstract. We present a novel hybrid method that includes a modulated scheme for reducing the distortion of the reconstructed image and a two-layered structure for grouping particip...
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...
Abstract. Several public key cryptosystems with additional homomorphic properties have been proposed so far. They allow to perform computation with encrypted data without the knowl...
