Binary secret sharing
t = 1 t = 1 secret sharing is trivial. The secret can simply be distributed to all n participants. t = n There are several (t, n) secret-sharing schemes for t = n, when all shares are necessary to recover the secret: Encode the secret as a binary number s of any length. Give to each player i aside from the last a random … See more Secret sharing (also called secret splitting) refers to methods for distributing a secret among a group, in such a way that no individual holds any intelligible information about the secret, but when a sufficient number of … See more Several secret-sharing schemes are said to be information-theoretically secure and can be proven to be so, while others give up this unconditional security for improved efficiency while … See more If the players store their shares on insecure computer servers, an attacker could crack in and steal the shares. If it is not practical to change the secret, the uncompromised … See more Secret sharing schemes are ideal for storing information that is highly sensitive and highly important. Examples include: encryption keys, missile launch codes, and See more A secure secret sharing scheme distributes shares so that anyone with fewer than t shares has no more information about the secret than someone with 0 … See more The trivial approach quickly becomes impractical as the number of subsets increases, for example when revealing a secret to any 50 of 100 players, which would require See more A player might lie about his own share to gain access to other shares.

WebJan 1, 2014 · Visual secret sharing (VSS), also called visual cryptography (VC) [32], encodes a binary secret image into n randomly appearing binary shares (printed on transparencies), and the decryption is performed by directly stacking k or more transparencies together. VSS has been studied intensively in recent years. Web5. Conclusion. This paper proposed a novel robust VSS scheme applying to QR code. In this scheme, all the codewords of the secret QR code image are split into temporary binary QR codes randomly with the theory of XOR-based VSS, so shares with high image quality and high imperceptibility can be achieved in the end. Each share in our scheme can be …
WebAug 6, 2024 · We work in a finite field K. This will usually be F 256 (the binary field with 256 elements), so that the sharing can be conveniently done on a per-byte basis. We want an m -out-of- n scheme, so the finite field must have at least n + 1 elements. For each value to share, a random polynomial P ∈ K [ X] of degree at most m − 1: we write P ...
