What is cryptography and why is it important?

Cryptography has a rich history and plays a crucial role in modern communication networks. Learn about data encryption techniques through an example where Alice and Bob use secret codes (ciphers) to communicate privately.

Why should you Learn Cryptography with cyberstart?

You may be learning cryptography from scratch or perhaps you already have some understanding of the subject and want to deepen your knowledge further. With CyberStart, you can try cryptography for yourself with hands-on, code-cracking challenges, or delve deeper into the theory to learn more about different methods of encryption and decryption.

What is a game in security?

The term “game” has substantially different meanings within the security area, depending on whether we speak about cryptographic security in particular, or system security in a more general setting that includes quantitative security with help of game theory.

What is a cipher & how does it work?

Think of [ciphers] as virtual locks. Ciphers allow Alice and Bob to scramble and descramble their messages so that they would appear meaningless if Eve intercepted them. Cryptography has been around for thousands of years. It has decided wars, and is at the heart of the worldwide communication network today.
