CSE206A: Lattices Algorithms and Applications (Fall 2021)

Schedule: Tue,Thu 11:00am-12:20am in CSE 4258
Instructor: Daniele Micciancio (CSE4214)

Course description

Point lattices are powerful mathematical objects that can be used to efficiently solve many important problems in computer science, most notably in the areas of cryptography and combinatorial optimization. This course gives a general introduction to the theory of point lattices, their algorithms, computational complexity, mathematical techniques, and applications to cryptography. Specific topics touched by the course include:

Prerequisites and Coursework

The main prerequisites for the course are general mathematical maturity, knowledge of basic mathematics (good linear algebra and probability theory, basic abstract algebra, and a little bit of calculus) and introductory level algorithms and complexity theory (mathematical models of computation, analysis of algorithms, polynomial time solvability, NP-hardness, etc.) Some prior knowledge of cryptography is useful, but not strictly required. No prior knowledge of advanced complexity theory, Fourier analysis, or algebraic number theory is assumed, but you should be prepared to learn a bit about all this through the course.

Coursework for students enrolled in the course will include a substantial amount of reading, 2 or 3 individual homework assignments, and a team project to be executed in groups of 2 or 3 students. Projects should be discussed with the instructor by the end of the 5th week of classes, and will be due during the 10th week. Each group should submit a written report, and possibly deliver a short presentation.

Reading Assignments

The course will be based on a combination of lecture notes, research papers and other online material as posted below. The list will be updated as the course moves forward. You can find information about additional topics to be covered on the web pages of previous editions of this course (Fall 2019, Fall 2017, Winter 2016, Spring 2014, Winter 2012, Winter 2010, Spring 2007, Winter 2002)
