Assessing Cryptographic Entropy

摘要

Systems, methods, software, and combinations thereof for evaluating entropy in a cryptography system are described. In some aspects, sample values are produced by an entropy source system. A typicality can be determined for each of the sample values. A grading is determined for preselected distributions based on the typicalities of the sample values. A subset of the preselected distributions are selected based on the gradings. An entropy of the entropy source system is calculated based on the subset of the plurality of distributions.

1. A method for assessing entropy in a cryptography system, the method comprising:
obtaining a plurality of sample values produced by an entropy source system; determining a grading for each of a preselected plurality of distributions, the grading being determined based on typicalities of the sample values; selecting a subset of the plurality of distributions based on the gradings; and calculating an entropy of the entropy source system based on the subset of the plurality of distributions.
