How Encryption of Network Traffic Works?

I recently started studying again, this time as an attempt of deep-diving into some security concepts for one of my PhD courses. It’s interesting how, as much as you try to escape from it, mathematics will sooner or later catch you somewhere and you will need to learn a bit more of it. At least that happened to me…

In this process I realised that if you go beyond simple security theory and network device configuration all other stuff is pure mathematics.

The reason behind my unplanned course in mathematics is explained through the rest of this text. It will explain what is network security and where is the math needed to get network communication secure. In the end, it was actually fun.



If you want two distant computers to talk with each other so that nobody else can see what they are talking about, you want to make a secure network connection between them. Security in this case means that you need to connect those machines to the network and be able to make the communication a secret communication. Secret communication through public communication system is possible by using encryption.
