UVM CS 295/395: Secure Distributed Computation (Fall 2020)


None yet.

Course Description

Techniques for secure computation involving multiple distributed parties, including applied cryptography, homomorphic encryption, secure multiparty computation, verified computation, and zero-knowledge proof. Applications including Bitcoin and other blockchain systems, Ethereum and other smart contracts, encrypted databases, and computing on encrypted data.

This is a programming-based course, with minimal theory background required. Programming projects may include:

Learning Objectives

By the end of this course, you will be able to:



Textbook & Other References

Please do not buy any books for this course. All required reference material is available online for free.

We will use the following textbooks for this course:

In addition to these, we will reference a number of academic papers throughout the semester.



Your grade for the course will be determined as follows:

Exams & Quizzes

There will be no exams for this course. There is no final exam, and this course will conclude before the University’s exam period.

Homework Assignments and Daily In-class Exercises

This course will use Python for examples and for programming assignments. Students are expected to be proficient in Python programming. Programming assignments will be distributed and turned in as Jupyter notebooks. Click here for instructions on installing Jupyter Notebook.

*Assignment Submission: Homework and in-class exercises will be turned in via Blackboard.

To submit an assignment:

  1. Complete the released Jupyter Notebook by filling in answers to all the questions
  2. Submit the notebook file (the .ipynb file) as your solution on Blackboard

Please do not change the name of the .ipynb file. This makes the grading process more difficult.

Please let me know if you have any questions about the submission process.

Late Work

Late work may be accepted, but you must make arrangements with me first. If you need to turn something in late, for any reason, please email me before the deadline. Depending on the circumstances, I may (or may not) impose a late penalty on your grade.

Collaboration & Allowed References

Collaboration on the high-level ideas and approach on assignments is encouraged. Copying someone else’s work is not allowed. Any collaboration, even at a high level, must be declared when you submit your assignment. Every assignment must include a collaboration statement. E.g., “I discussed high-level strategies for solving problem 2 and 5 with Alex.”

The official references for the course are listed in the schedule below. Copying from references other than these is not allowed. In particular, code and proofs should not be copied from other sources, including Stack Overflow and other public sources.

Students caught copying work are eligible for immediate failure of the course and disciplinary action by the University. All academic integrity misconduct will be treated according to UVM’s Code of Academic Integrity.

Final Projects

The course will include a final project, completed in groups of 1-3 students. The final project will demonstrate your mastery of the concepts covered in this course.

In keeping with University policy, any student with a documented disability interested in utilizing accommodations should contact SAS, the office of Disability Services on campus. SAS works with students and faculty in an interactive process to explore reasonable and appropriate accommodations, which are communicated to faculty in an accommodation letter. All students are strongly encouraged to meet with their faculty to discuss the accommodations they plan to use in each course. A student’s accommodation letter lists those accommodations that will not be implemented until the student meets with their faculty to create a plan. Contact SAS: A170 Living/Learning Center; 802-656-7753; access@uvm.edu; or www.uvm.edu/access

Religious Holidays

Students have the right to practice the religion of their choice. Each semester students should submit in writing to their instructors by the end of the second full week of classes their documented religious holiday schedule for the semester. An arrangement can then be made to make up the missed work.

Student Athletes

In order to be excused from classes, student athletes should submit appropriate documentation to the Professor in advance of all scheduling conflicts within the first two weeks of class. Those missing class are expected to submit make-up assignments within a reasonable time period.
