Binary Randomness Test

This procedure is designed to evaluate the randomness of a sequence of bytes generated by a source. The test is conducted using statistical analysis with the help of online tools.

Purpose

The purpose of this procedure is to determine if a given sequence of bytes exhibits characteristics of randomness. It utilizes statistical tests to analyze the distribution of ones and zeros within the byte sequence.

Tools Used

• Selenium: For web automation to interact with online tools.
• Requests: For making HTTP requests.
• Chrome WebDriver: Used for browser automation.

Procedure Overview

• Record the start time of the procedure.
• Initialize the WebDriver for Chrome.
• Navigate to random.org to generate a sequence of random bytes.
• Configure the byte generation settings (e.g., number of bytes).
• Retrieve the generated byte sequence.
• Format and preprocess the byte sequence.
• Calculate the count of ones and zeros in the sequence.
• Compute the absolute difference between the counts.
• Calculate the test statistic (Sobs).
• Perform statistical analysis using online tools to determine randomness.
• Record the end time of the procedure.
• Calculate the elapsed time of the procedure.

How to Use

• Ensure Python and the necessary libraries (selenium, requests) are installed.
• Download and configure the appropriate WebDriver for Chrome.
• Run the script and observe the output.
• Interpret the results based on the statistical analysis.

Note

• This procedure utilizes online tools for statistical analysis. Ensure a stable internet connection.
• Adjust the byte generation settings and statistical parameters as needed.
• Results may vary depending on the randomness of the generated byte sequence.
