Exploring Symmetric and Asymmetric Cryptosystems

Scenario : A small organisation is reviewing its policy for protecting internal messages exchanged between its
employees. Historically it has used a mixture of classical and modern cryptographic techniques, but
the company now wants to understand what these methods actually protect, where their weaknesses
lie and how greater security might be achieved.
As a cryptographic specialist, you have been asked to investigate the set of examples, demonstrate
how the algorithms work and explain what an attacker could and could not achieve. Your specific data
will be supplied as a “data sheet” e-mailed individually to each student. (This will not be the same for
all students.) You will present your findings as a short technical report, as well as a short video
presentation (instructions to follow).
