Linear secret sharing scheme matrix example
Nettet23. feb. 2024 · Linear Secret Sharing Scheme (LSSS) provides a smart way to share secrets through linear matrices. On the one hand, LSSS can present arbitrary … NettetFor linear secret-sharing schemes, we obtain a similar result, independent of the field size. Corollary 3. If a linear secret-sharing scheme (over an arbitrarily large field) with n parties and threshold k is (1,ε)-leakage-resilient, then it must hold that ε 1 2k k. Consequently, if it is (1,exp(−Θn))-leakage-resilient, it must hold that ...

Nettet30. sep. 2024 · Quantum secret sharing plays an important role in quantum cryptography. In this paper, we propose a new general quantum secret sharing scheme based on access structure and monotone span program. In our scheme, the secret distributor first distributes the secret share according to the access structure, and then each … NettetAnother example of a linear secret sharing scheme, which is widely used in secure computation nowadays is additive secret sharing. Additive secret sharing, unlike Shamir’s secret sharing is a scheme for the \( (n,n)\)-threshold access structure.
Nettet1. jan. 2024 · Definition 2 Linear Secret Sharing Scheme. A secret sharing scheme Π over a set of parties P with secret s ∈ Z p is linear (over Z p) if: 1. The shares of each party from a vector over Z p. 2. There exists a matrix M ∈ Z p l × n. For all i ∈ Z l, the i th row of M is associated with an attribute ρ(i). NettetAbstract. Linear Secret Sharing Scheme (LSSS) matrices are commonly used for implementing monotone access structures in highly expressive Ciphertext-Policy Attribute-Based Encryption (CP-ABE) schemes. However, LSSS matrices are much less intuitive to use when compared with other approaches such as boolean formulas or access trees. …
NettetA secret sharing scheme \Pi over a set of parties \mathcal{P} is called linear (over \mathbb{Z}_p) if: (1) the sares for each party form a vector over \mathbb{Z}_p.
