Proceso por el que se genera una clave a partir de cierta información secreta y, opcionalmente, alguna información adicional.
A function in the
lifecycle of keying material; the process by which one or more keys are derived
from a shared secret and other information. [NIST-SP800-57:2007]
a function that
maps octet strings of any length to octet strings of an arbitrary, specified
length, such that it is computationally infeasible to find correlations between
inputs and outputs, and such that given one part of the output, but not the
input, it is computationally infeasible to predict any bit of the remaining
output. The precise security requirements depend on the application.
[ISO-18033-2:2006]
a key derivation function outputs one or more shared secrets, used as keys, given shared secrets and other mutually known parameters as input. [ISO-15946-3:2002]
