Support a security strength

Definition(s):

  A term applied to a method (e.g., an RBG or a key with its associated cryptographic algorithm) that is capable of providing (at a minimum) the security strength required or desired for protecting data. A security strength of s bits is said to be supported by a particular choice of keying material, algorithm, primitive, auxiliary function, parameters (etc.) for use in the implementation of a cryptographic mechanism if that choice will not prevent the resulting implementation from attaining a security strength of at least s bits.
