Introduction (Inleiding)
Building on the bachelor “Security” course and the course on cryptographic protocols, this course provides application perspectives on cryptography. This is a course for students interested in hardware and software design in industry i.e. real-world security applications. The course is devoted to the state-of-art in cryptographic hardware and embedded systems. The students will learn about implementation techniques as well as about cryptanalysis of the cryptographic devices. An important aspect is to learn about numerous pervasive applications of security running on extremely constrained platforms such as mobile phones, RFID tags, contactless cards etc. requiring special so-call lightweight cryptography.
