A number associated with the amount of work (that is, the number of operations of some sort) that is required to break a cryptographic algorithm or system in some way. In this Recommendation, the security strength is specified in bits and is a specific value from the set {112, 128, 192, 256}. If the security strength associated with an algorithm or system is S bits, then it is expected that (roughly) 2S basic operations are required to break it.
