Application deadline

Applicants from Nordic countries: 1 June for the autumn semester and 1 December for the spring semester. Exchange students and Fulbright students: 15 April for the autumn semester and 1 October for the spring semester.

Type of course

The course can be taken as a singular course.

Admission requirements

Admission requirements: Higher Education Entrance Qualification + specific entrance requirements equivalent to MATRS: R1/(S1+S2). Application code: 9354 - Singular course in computer science

Course contents

The course focuses on properties of communication between computers, and the machinery needed to faciliate the communication. Among the properties are those arising from the uncertainty of delivery, the omnipresence of errors, and lack of global consistence and authority. There are many technical solutions; their design and implementation is discussed. As computers are used to manipulate 'real world' valuables ever more demans are placed on Authentication, Authorization, and Auditing. Accross a network, only cryptographic technology can assist in upholding interesting properties. Both symmetric- and assymetric encryption will be presented and discussed.

Recommended prerequisites

INF-1101 Data structures and algorithms

Objective of the course

It is expected that the students, after following the course, have an in depth knowledge of challenges and solutions related to providing reliable and secure communication between computers. This includes knowledge and understanding of the layered Internet architecture, services related to each layer, current communication protocols, and security issues and available solutions.

The students should be able to design and implement low-level network protocols that enable communication between computers. The students should also be able to design and implement solutions that use encryption as a secure element in communication.

Language of instruction

The language of instruction is English and all of the syllabus material is in English. Examination questions will be given in English, but may be answered either in English or a Scandinavian language.
