Contents:Stories about the German ENIGMA device, cracked by the Allied forces in WWII, are widely known. Until about 1970, use of cryptography was limited to military and diplomatic applications, but nowadays cryptography is essential to the entire society.

Cryptography has seen enormous scientific development over the past thirty years. Encryption is used for sending messages over a network, for safe storage on disk, to protect embedded software against reverse engineering, and to scramble paid TV channels. GSM cellular calls are also encrypted. The course explains how encryption works and how keys are chosen.

Still, confidentiality fills only half the course. The second part is devoted to cryptographic protocols, used to verify the identity of persons and the origin of electronic documents. We consider the computation of functions with secret inputs, and the use of shared keys. The course also covers some theory and algorithms about big integer numbers and modular computing.

Literature:May change!
The literature for this course is the book: Gerard Tel, Cryptografie: Beveiliging van de Digitale Maatschappij, Addison-Wesley 2002.
It is no longer available from the publisher but will be printed as a lecture note. The book is in Dutch, but for foreign students alternative literature is found on the course pages.
Course form:Two weekly lectures plus a working session, individual case study, presentations by students.
Exam form:Two written exams, paper, presentation.
Minimum effort to qualify for 2nd chance exam:To qualify for the retake exam, the grade of the original must be at least 4.
