What is Guessing Entropy? 


A guessing entropy is a measure of the difficulty that an Attacker has to guess the average password used in a system. In this document, entropy is stated in bits.  When a password has n-bits of guessing entropy then an attacker has as much difficulty guessing the average password as in guessing an n-bit random quantity. The attacker is assumed to know the actual password frequency distribution.
