Lectures in which the contents of the subject will be exposed. Lab classes where students solve real situations that can be found in practice.
There will be two tests in which the total content corresponding to Secret Key Cryptography has a weight of 20% of the final grade and the total content corresponding to Public Key Cryptography has a weight of 40% of the final grade. These two tests may be replaced by a final examination.
The other 40% of the grade will correspond to the laboratory.
