Cryptography and Security

Master Course (Fall semester)

Serge Vaudenay (lectures)

Scope

Introduce basic cryptography: choose the appropriate cryptographic primitive in a security infrastructure, judge the strength of existing standards, assess / evaluate the security based on key length. Implement algorithms manipulating big numbers and use number theory, use algebra and probability theory to analyze cryptographic algorithms, identify the techniques to secure the communication and establish trust.

Contents

• Ancient cryptography: Vigenère, Enigma, Vernam cipher, Shannon theory
• Diffie-Hellman cryptography: algebra, Diffie-Hellman, ElGamal
• RSA cryptography: number theory, RSA, factoring
• Elliptic curve cryptography: elliptic curves over a finite field, ECDH, ECIES, pairing
• Symmetric encryption: block ciphers, stream ciphers, exhaustive search
• Integrity and authentication: hashing, MAC, birthday paradox
• Public-key cryptography: cryptosystem, digital signature
• Trust establishment: password-based crypto, secure communication, trust setups, SAS-based crypto
• Case studies: mobile telephony, Bluetooth, WiFi, WhatsApp, Bitcoin,TLS, biometric passport, EMV

Student Seminar: Security Protocols and Applications

Master Course (Spring semester)

Serge Vaudenay and Betül Durak

Scope

We will look at today's most popular security protocols and new kinds of techniques and problems that will play an emerging role in the future. This course will be held as a seminar, in which the students shall actively participate. The talks will be assigned to teams of one or two students. Each team will give a 35 minutes talk, answer to other students' questions and write a 3-4 pages summary on the selected subject. The talks will be given in English. A copy of the slides (in pdf format, also provided by each team) shall be made available online before each presentation.
