Key share
Key share
One of n parameters (where n ≥ 2) such that among the n key shares, any k key shares (where k ≥ n) can be used to construct a key value, but having any k−1 or fewer key shares provides no knowledge of the (constructed) key value. Sometimes called a cryptographic key component or key split.
