Modern cryptography studies techniques for facilitating
interactions between distrustful entities. Today, with the
advent of the Internet, these techniques become indispensable –
enabling, for instance, anonymous electronic elections,
privacy-preserving electronic auctions, internet banking and
more. In this course we introduce some of the fundamental concepts of
Note: This will be a theory course. You will be expected to read and write formal definitions and mathematical proofs. This is not a course in security: you will not learn how to secure your system. Cryptography is only one (important) part of security. We will not study cryptographic acronyms or all cryptographic protocols in use today. Rather we focus on some of the fundamental design paradigms and on notions that will allow you to critically evaluate cryptographic protocols.
Topics Include: one-way functions, private-key/public-key
encryption systems, digital signatures, zero-knowledge,
secure-multiparty computation and its applications.
CS 280 (or equivalent), MTH150 (or mathematical maturity), or
permission of instructor.
The main skills that will be assumed from these courses are: 1) the ability to understand and write formal mathematical definitions and proofs and 2) comfort with reasoning about algorithms, such as proving their correctness and analyzing their running times. It is also important that you are familiar with basic probability.
There will be roughly 4-5 homeworks and 2 exams. Students taking the graduate course will be expected to do a final project. The grade will be based on homework assignments, exams and class participation (and the final project).
You are free to collaborate with other students on the homework, but you must turn in your own individually written solution and you must specify the names of your collaborators. Additionally, you may make use of published material, provided that you acknowledge all sources used. Note that it is a violation of this policy to submit a problem solution that you are unable to explain orally to me. Typed problem sets are strongly preferred.
Lecture notes covering a large fraction of the course can be found here (course notes developed by Rafael Pass and Abhi Shelat).
There is no required text for the course other than lecture notes. You may find the following two books to be useful references. Note, however, that we will not always be following the same notational conventions as these books.
Jonathan Katz and Yehuda Lindell. An Introduction to Modern Cryptography. This is an introductory textbook on cryptography. The level of the material and the mathematical treatment is similar to the one we will use in class. However, this book does not cover all of the material that we go through.
Oded Goldreich. Foundations of Cryptography. This is a very comprehensive treatment of the theoretical foundations of cryptography. Volume I and II include most of the material that we cover in class, but at a far greater depth and (at a more advanced level). This book is a great reference for students interested in more advanced studies in theoretical cryptography.
For a more applied treatment of cryptography, I suggest the following book which is available on-line.
Alfred J. Menezes, Paul C. van Oorschot, and Scott A. Vanstone. Handbook of Applied Cryptography.
For background reading on probability, algorithms, and complexity theory, I recommend:
Thomas H. Cormen , Charles E. Leiserson , Ronald L. Rivest, and Clifford Stein. Introduction to Algorithms.
Michael Sipser. Introduction to the Theory of Computation.
