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…

This week, we will see the ElGamal encryption scheme; we are considering public key cryptography, so we use public and secret keys to achieve this encryption scheme.

Oxbridge Inspire’s ‘Exhibition of Ideas’ workshop was at Coopers’ Company and Coborn School last week for their STEM Festival, where we encouraged sixth form students to explore STEM topics, skills and career options with an open mind.
