How to Create a Strong and Secure Encryption Algorithm

Creating a powerful encryption algorithm is not something to be taken lightly. While it might seem tempting to develop your own cryptographic solution, experts strongly advise against it unless you have a deep understanding of the complex field of cryptography.

Efforts such as the Telekom's MAGENTA, an 8-year project with a team of experts, were scrutinized and found vulnerable. Even established libraries like OpenSSL, known for their robustness, have faced significant security breaches like Heartbleed, highlighting the complexities involved in secure encryption.

Why You Shouldn't Create a New Crypto Algorithm

The process of designing and implementing a secure encryption algorithm is extremely difficult. Small errors can lead to catastrophic failures. The notorious Heartbleed bug in OpenSSL, which exposed sensitive information due to a coding error, serves as a stark reminder of the importance of rigorous testing and peer review.

How to Make Your Encryption Stronger

Instead of attempting to create a new encryption method, there are more practical approaches for enhancing security:

Use Existing Algorithms: Utilize well-established and peer-reviewed encryption methods such as the Enigma (rewired with modern techniques), one-time pad encryption using atmospheric noise, or established cryptographic libraries. Learn the Fundamentals: Deepen your understanding of cryptography through extensive study of mathematics and computer science with a focus on cryptography. Resources like David Kahn's The Codebreakers and Seizing the Enigma provide valuable insights. Consult Experts: Engage with experts in the field, and consult books like Bruce Schneier's Applied Cryptography, which offers a comprehensive introduction to the subject.

Steps to Design a Secure Cryptographic Scheme

For those aspiring to contribute to the development of secure cryptographic systems, here are some steps to consider:

Study Thoroughly: Begin by getting a copy of Applied Cryptography or a similar introductory text and read it thoroughly. If you find the material challenging, it's a sign that you may need to invest more time and effort. Acquire a PhD in Mathematics: Gain a deep understanding of relevant mathematical concepts, including group theory, number theory, and elliptic curves. These are foundational to advanced cryptographic techniques. Design with Challenges: Keep in mind the adage: "Anybody can design a crypto scheme they can't break, designing a crypto system that well-funded, talented teams can't break is a lot harder." Anticipate a significant timeframe, possibly 10-20 years, for your efforts to align with industry standards.

Conclusion

The path to creating a truly secure and powerful encryption algorithm is fraught with challenges. It is advisable to leverage existing, well-established methods and develop a solid foundation in cryptography before embarking on any new projects. By doing so, you can contribute to the advancement of cybersecurity in a more effective and secure manner.
