Entropy Analysis

Entropy is a useful analysis technique in cyber security as it can be used to identify encrypted or compressed data, detect malware, and identify data types. It is a measure of the uncertainty or information content in a set of data. It quantifies the average amount of information needed to describe the data. The entropy value ranges from 0 to 7. When the entropy is 0, it means the data is perfectly predictable or has no uncertainty, as all the values in the dataset are the same. Conversely, when the entropy is 7, it indicates maximum uncertainty or randomness, where all possible values are equally likely to occur. In general, higher entropy values signify greater complexity or information diversity in the dataset.

Entropy

Shannon entropy, named after mathematician Claude Shannon, is a measure of the uncertainty or information content in a set of data. It quantifies the average amount of information needed to describe the data. The entropy value ranges from 0 to 7. When the entropy is 0, it means the data is perfectly predictable or has no uncertainty, as all the values in the dataset are the same. Conversely, when the entropy is 7, it indicates maximum uncertainty or randomness, where all possible values are equally likely to occur. In general, higher entropy values signify greater complexity or information diversity in the dataset.

Block Size

The block size is the number of characters used to calculate the entropy of the input data. For example, if the block size is 8, the input data is divided into blocks of 8 characters each, and the entropy is calculated for each block.
