Abstract

The previous part of the series of articles dealing with cryptography has been concluded with an explanation of trapdoor one-way functions. These functions are important since using them we are able to construct asymmetric ciphers. We concluded the previous part that we need to be familiar with the so-called modular arithmetic. This arithmetic differs from the usual one in several ways. Therefore, in this part we try to explain the modular arithmetic in detail. Moreover, we go back to asymmetric encryption and explain how RSA encryption works and how it is used in practical applications (for instance, in digital signature). This part is also accompanied by two assignments.
