A key selection algorithm is similar to a key derivation algorithm in that it takes a secret input and produces a secret output stream. However, unlike key derivation algorithms, there is no expectation that the input cannot be reconstructed from the output. Key selection algorithms are exclusively meant to be used on the output of a key agreement algorithm to select chunks of the shared secret.
