Public Key Cryptography

This paper provides a practical introduction to the field of cryptography, with a focus on public-key cipher systems. The key concepts of the field are explained using simple-to-understand real-world examples that demonstrate the problems different encryption systems set out to solve. Building on that, the RSA algorithm - a widely used public-key encryption system based on the factorization of large prime numbers - is introduced. After the mathematical concept has been established, the algorithm is again demonstrated using a simple example. The paper closes with a brief consideration of the security aspects of RSA and an outlook on the future.
