Introduction to Cryptography (89-656)
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 syllabus can be found here in pdf.
Exercises can be handed in at class, or sent by email to Hila Dahari. Please make sure that any scanned solutions are clear and are sent in a single PDF file.
Solutions will be provided in class.
