意味（1）

(engineering) A key split at one end like a split pin, for the same purpose.

A split pin is also a split key, because both are used to lock or fasten pieces of machinery together.

意味（2）

(computing) A key value used to identify where to split the children of a parent node in a B-tree or similar data structure.

As with B+-trees, records with keys greater than or equal to the split key go to a new current node, records with keys less than the split key remain in the original node.

意味（3）

(cryptography) A cryptographic key that is divided into two or more values that individually cannot be used to deduce the entire key.

Moreover, even those systems (such as split key systems) that can decrease these risks, do so with a marked increase in cost.
