Mass Serialization Method for Document Encryption Policy Enforcement
Margaret Sturgill, Steven J. Simske · 2016
Analytics obtained during the creation of a database of mass serialized codes can also be used to help enforcement of encryption policy on documents. In this paper, we introduce a set of metrics which complement traditional NIST cryptography methods -- 4 mass serialization and one entropy metric -- which in combination can allow a discrimination between encrypted vs. zipped files. We describe the use of these methods to identify a broad range of non-randomness in number sets, and apply them to a more mundane problem-that of automatic assessment of the encryption state of a corpora of documents.
