252-0407-00LCryptography Information W7 credits3V + 2U + 1AU. Maurer
AbstractFundamentals and applications of cryptography. Cryptography as a mathematical discipline: reductions, constructive cryptography paradigm, security proofs. The discussed primitives include cryptographic functions, pseudo-randomness, symmetric encryption and authentication, public-key encryption, key agreement, and digital signature schemes. Selected cryptanalytic techniques.
ObjectiveThe goals are:
(1) understand the basic theoretical concepts and scientific thinking in cryptography;
(2) understand and apply some core cryptographic techniques and security proof methods;
(3) be prepared and motivated to access the scientific literature and attend specialized courses in cryptography.
ContentSee course description.
Lecture notesyes.
Prerequisites / NoticeFamiliarity with the basic cryptographic concepts as treated for
example in the course "Information Security" is required but can
in principle also be acquired in parallel to attending the course.

Lecture notesthe lecture notes are in German, but they are not required as the entire
course material is documented also in other course material (in english).
Prerequisites / NoticeA basic understanding of fundamental cryptographic concepts
(as taught for example in the course Information Security or
in the course Cryptography) is useful, but not required.
263-4600-00LFormal Methods for Information Security Information W4 credits2V + 1US. Radomirovic, M. Torabi Dashti
AbstractThe course focuses on formal methods for the modelling and analysis of security and privacy concerns in critical systems, ranging from access control policies to cryptographic protocols.
ObjectiveThe students will learn the key ideas and theoretical foundations of formal modelling and analysis of security protocols and policies. The students will complement their theoretical knowledge by solving practical exercises and using various related tools.
ContentThe lecture treats formal methods for the modelling and analysis of security-critical systems.

The first part of the lecture focuses on access control policies in centralized and distributed settings. Access control policies are an integral part of modern Internet services; examples include single sign-on endpoints, distributed trust management in social Websites, and peer-to-peer networks. The lectures cover the formal foundations of authorization systems, and their applications to the synthesis and analysis of access control policies. We will also study a few notable existing models, such as XACML, DKAL and PBel.

The second part of the lecture concentrates on cryptographic protocols. Cryptographic protocols (such as SSL/TLS, SSH, Kerberos, SAML single-sign on, and IPSec) form the basis for secure communication and business processes. Numerous attacks on published protocols show that the design of cryptographic protocols is extremely error-prone. A rigorous analysis of these protocols is therefore indispensable. The lecture covers the theoretical basis for the formal modeling and analysis of such protocols. Specifically, we discuss their operational semantics, the formalization of security properties, and techniques and algorithms for their verification. In addition to the classical security properties for confidentiality and authentication, we will study privacy properties and the fairness property in contract signing. The accompanying tutorials provide an opportunity to apply the theory and tools to concrete protocols.
