Credit level (Normal year taken)SCQF Level 11 (Year 4 Undergraduate) AvailabilityAvailable to all students
SCQF Credits10 ECTS Credits5
SummaryCryptography is the formal study of the notion of security in information systems. The course will offer a thorough introduction to modern cryptography focusing on models and proofs of security for various basic cryptographic primitives and protocols including key exchange protocols, commitment schemes, digital signature algorithms, oblivious transfer protocols and public-key encryption schemes. Applications to various problems in secure computer and information systems will be briefly discussed including secure multiparty computation, digital content distribution, e-voting systems, digital payment systems, cryptocurrencies.
Course description The area of cryptography focuses on various problems pertaining to secure communication and computation. It entails the study of models that express security properties as well as the algorithms and protocols that are the implementation candidates for satisfying these properties. An important dimension of modern cryptography is the design of security proofs that establish security properties. Such proofs are conditional on assumptions that fall in two categories: "system assumptions" such as the faithful execution of code, or the availability of private randomness and "computational assumptions" that are related to the computational complexity of various problems (including factoring large numbers and others). Students will learn to model security problems, design protocols and prove them secure under precisely formulated system and computational assumptions.
