Web4 mrt. 2024 · In this paper, we based on the quantum Fourier transform and monotone span program design a hybrid secret sharing. This hybrid scheme has the advantages of both classical and quantum secret sharing. For example, it has general access structure, and is secure against quantum computation and eavesdropper attacks. WebIn the monotone case our new methods yield n (logn) lower bounds for the monotone span program complexity of explicit Boolean functions in nvariables over arbitrary elds, improving the previous lower bounds on monotone span program size. Our characterization of span program size implies that any matrix with superpolynomial … how to make sandbags with soil https://techmatepro.com

Web1 mei 2024 · Monotone span programs over rings (in particular over integers \(\mathbb {Z}\)) were introduced in [10, 12] and it turns out that they have a similar correspondence with black-box secret sharing schemes. In addition, monotone span programs over rings are the basis for multi-party computation over black-box rings, as studied in . WebA Monotone Span Program (or MSP) is a cryptographic technique for splitting a secret into several shares that are then distributed to parties or users. (Have you heard of Shamir's Secret Sharing?
