Introduction to Cryptography (89-656)
Yehuda Lindell
The aim of this course is to teach the basic principles and concepts of modern cryptography. The focus of the course will be on cryptographic problems and their solutions, and will contain a mix of both theoretical and applied material. We will present definitions of security and will prove the security of the constructions we see according to these definitions. We will follow the textbook Introduction to Modern Cryptography, 2nd Edition by Jonathan Katz and myself.
The course consists of twelve lectures of four academic hours each (three hours of actual lectures).
The course has been filmed (in Hebrew), and all videos can be found here.
Syllabus
