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.
