CouCouGen: A Lightweight Pseudorandom Generator with Coupled Counters — Theory, Implementation, and Practical Considerations

Key Points

• The aim is to describe the theory and practical implementation of CouCouGen, a lightweight PRNG.
• Developed a pseudorandom number generator using three coupled counters with a 96-bit state.
• Provided a JavaScript implementation under the MIT license.
• Conducted statistical tests to assess performance.
• The CouCouGen exhibited favorable performance in statistical tests for randomness.
• Demonstrated practical applications despite certain limitations of the generator.
