Description
Secret Sharing is the splitting up of a secret amongst a group such that no individual can learn the entire secret alone, but when a sufficient amount of the group comes together with their parts of the secret, they can reconstruct the secret.
Parameters
$n$: size of the group the secret is being shared with
$t$: threshold number of players
Table of Algorithms
| Name | Year | Time | Space | Approximation Factor | Model | Reference |
|---|---|---|---|---|---|---|
| Shamir's scheme | 1979 | $O(t^{2})$ for secret computation? (requires polynomial interpolation) | $O({1})$ per person, $O(t^{2})$ to figure out secret? | Exact | Deterministic | |
| Blakley's scheme | 1979 | $O(t^{3})$ for secret computation? (requires linear solver) | $O(t)$ per person, $O(t^{2})$ to figure out secret | Exact | Deterministic |
