General description and relevant information The main goal of this course is to introduce the main cryptographic schemes, the main security notions, and to analyse the use of cryptography in the digital world. The first part of the course is dedicated to symmetric key cryptographic schemes, hash functions, and pseudorandom functions. Then we introduce the public-key cryptography paradigm, protocols for key exchange, public-key encryption schemes, and digital signatures. The last part of the course is dedicated to the security analysis of messaging applications and cloud services, blockchain technology, cryptocurrencies, post-quantum cryptography, and secure multiparty computation.

 Students have to perform two practical works.

The first practical work comprises the first units of the course. It consists on a list of exercises that have to be solved individually.

The second practical work comprises the second part of the course. It is the analysis of a product or service using cryptography (cloud, social networks, messaging apps,...) or a scientific paper.

Practical works are individual.

Both practical works have the same weight, i.e. a 35% each of them.

Passing both practical works is required to pass the course, i.e. the students have to obtain at least 5 in each of the practical works to pass the subject.
