One Time Pad

This week, we will look at the one time pad. In short, this is an encryption technique that cannot be broken. We saw in the tutorial about hard problems, that we often have to prove security relative to a hard problem we assume is not feasible to break; using a one time pad means we do not need to rely…

Hash functions

This week, we will look at cryptographic hash functions. These are another widely used tool in modern cryptography that allow for secure communication. In brief, they take an input and scramble or ‘hash’ it to form an output — they are a way to hide information. In this tutorial, we will look at what…
