Course Description
This class is meant to open to you research in Cryptography, both theoretical and applied. To do so, the class will involve reading research papers, reviewing them, discussing them, and doing a project.
Course Setups and Requirements: At the beginning of the course, I will give some lectures on the bare basics of cryptography for 4 lectures.
Next, the class will move to reading research papers. In each class, we will read one or two papers. Two students will be assigned as the lead for each paper, who will be responsible in understanding the paper thoroughly, and do the following. (Collaboration is strongly recommended.)
 Write a review for the paper. The review should be at most one page, summarizing the context, content, and your evaluation. When writing a review, think about reading it yourself and trying to quickly obtain an overview of the paper. A template is here [tex]. The review needs to be posted on Piazza 24 hours before the class.
 Prepare and give an 1 hour presentation of the papers. You can use the board, or slides, or a combination of them. There is no restriction on the forms of presentation. You can present sequentially, each 30 minutes, or act a play together, or anything else.
 Lead a discussion of the paper in the remaining 30 minutes of the class about the strength and weakness of the paper, and open questions following the paper.
What papers will we read? There are many exciting research directions in theoretical and applied cryptography, such as, the following ones and many others.
 Program Obfuscation
 Computing over encrypted data (Fully Homomorhpic Encryption (FHE), Functional Encryption (FE))
 Failures of Cryptography (Cryptanalysis and Attacks)
 Crypto Currency (Bitcoin) and Smart Contracts (Ethereum)
 Memory Hard Functions (e.g., Script, Argon 2)
 Cryptographic protocols (e.g., TLS/SSL, secure multiparty comptuation protocols)
 Secure Processor (e.g., Intel SGX)
 Cloud Computing Techniques (e.g., Verifiable Computation, Oblivious RAM)
 PostQuantum Cryptography (e.g., Lattice based crypto)
 and many many more
I will publish an initial list of papers of my choice (see below). But you should also contribute to the list. One first task to you is contributing to the list as many papers you recommend, and at least one, by the end of the second week. You can find interesting papers on cryptography in top crypto venues (EuroCrypt, Crypto, TCC) or in top security venues (Security and Privacy, Usenix Security, CCS, NDSS). You do not need to be restrcted to the topics mentioned above, but the paper must be related to crypto. Your participation is very important, since it tells me your interests and your interests shape what topics we will study in class.
Assignment of lead students Then I will pick a subset of the papers from our list and assign two lead students to papers. I will assign you papers close to your interests. In addition, you can swap assigned papers between youselves based on mutual agreement. Report back to me which papers you are the lead for by the end of the third week. We have around 10 classes for paper reading. This means suppose there are 10 students in class, each student will be lead twice. If there are more students, we will assign more lead students per class.
Projects Another component of the class is project. You can form teams of two for the project. There are two milestones.
 By the end of the 6th week, you need to decide on your project, and submit to me the slides of a pitch of 10 mins about what your project is and why it is a meaningful project. Then, each group will present their pitch in the following weeks. I will see how the pitch presentation fits into the schedule later.
 By the middle of the final week, you need to hand in the final report.
Final assessment will depend on a combination of presentation 35%, inclass participation 15%, and final project 50%.
