Secure Autonomous Systems

Instructor: Prof. Sibin Mohan, The George Washington University

CSCI 6907/3907 | Spring 2024 | TR 12:45PM - 02:00PM ET | TOMP 310

This course will focus on the state-of-the-art on security for autonomous and cyber-physical systems. The goal is to provide a deep and broad understanding of the design of such systems as they interact with the real world. Autonomous cars, unmanned aerial/ground/water vehicles, robots, etc. are examples of systems that we intend to explore.

We will cover topics related to:

• design of autonomous, cyber-physical and real-time systems
• sensing, IMU, GPS, Radar, LIDAR, Camera, etc.
• localization, Simultaneous localization And Mapping (SLAM)
• Extended Kalman Filter (EKF)
• attacks and defenses related to all of these topics
• privacy and ethical issues in the design and deployment of autonomous systems

Hands-on exercises will explore real hardware rovers as well known, open-source simulation and control platforms such as:

• Gazebo
• VEINS

The course will also include an exploration of the state-of-the-art research papers in these domains.
Note: this student-led component is a major component of this course, i.e., reading papers, critiquing them and learning to present work by other researchers.

Prerequisites: students should be familiar with one or more modern programming languages such as Python, C++, etc. The hands-on machine problems will involve the setting up of open-source simulation frameworks (detailed instructions will be provided).

Grading Criteria

• one point is counted for each submission
• at the end of the semester, we will calculate the total of these points, say 'p'
• we then compute the ratio of 'p' to the total number of papers, 'P', i.e. p/P (let's call this 'ratio_p')
• the paper critique grade is then multiplied by this ratio to get the final grade for this component, i.e., (ratio_p)*(grade_p)

Conversion from numerical to letter grade is as follows:

Expectations and Responsibilites

Student Responsibilites: Students must,

• Conduct your online behavior in accordance with the class' Professional and Social Contract
• Attend all classes and labs unless you are sick or there is an emergency in which cases you must contact the professor via email before class
• Interact, ask questions, and generally participate in class discussions
• Do group exercises assigned during lectures and/or labs
• Be respectful when working in a group, and make sure that everyone's ideas are heard and taken seriously
• Complete all work in accordance with the academic honesty rules for the university and for the class
• Work to digest and process all provided material including Blackboard and Discord discussions (you cannot ignore Discord or Blackboard)
• Contact the Professor if you are worried about completing any responsibilities

We also need your feedback for parts of the class that aren't working for you. We do our best in running the class, but certainly make mistakes, or overlook different aspects. Class evaluations are of limited use since they only are given at the end of the class. Please provide feedback using the linked feedback form on Piazza.

Professor and Instructional Staff Responsibilities

You should depend on the instructional staff (including Sibin) for the class to:

• be clear about student's responsibilities in the class
• convey the course's materials on this webpage, on Discord and Blackboard, in class, and in lab in a manner that is approachable and understandable to every single student
• provide an environment in which everyone feels open to ask questions, and seek to remedy any misunderstandings or confusions
• provide additional material on demand if anyone is curious about knowledge beyond the scope of the class

Further, it is our intent that students from all diverse backgrounds and perspectives be well-served by this course, that students’ learning needs be addressed both in and out of class, and that the diversity that the students bring to this class be viewed as a resource, strength and benefit.

It is our intent to present materials and activities that are respectful of: gender identity, sexuality, disability, age, socioeconomic status, ethnicity, race, nationality, religion, and culture.

Your suggestions are encouraged and appreciated. Please let us know ways to improve the effectiveness of the course for you personally, or for other students or student groups.

Late Submissions for MPs

Submission/due dates are announced along with the MP descriptions.

You have a total of 3 "grace" days to use during the term. You can use those to submit whatever assignment(s) you want late. E.g. you can turn in one assignment 2 days late, the other 1 day late. Or turn in 3 assignments, each 1 day late. If you want to use these late days, indicate so in the comment box when you submit it.

You start losing 20% of the points per day after the grace days you use. E.g., if the assignment is due on Tuesday, and you turn it in on Wednesday without saying anything, you lose 20 points. If you use 1 grace day, and turn it in on Wednesday, you don't lose any points; but if you turn it in on Thursday, your final grade will be Your Earned Grade - 20. On Friday, it will be Your Earned Grade - 40.

An assignment can be at most three days late: so in our example, if you turn in the assignment Saturday, the grade is 0.

The point of this policy is to balance the need to be fair to those who turn in their assignments on time, with the need to recognize that sometimes, stuff happens and you just can't do all that's expected of you. Why have deadlines at all? Because almost everything in life does, and this is a small-stakes environment to practice that. Also, we can't grade everything at once.

Collaboration, the Honor Code and Cheating

You are encouraged to work together. You may discuss the MPs with other people to understand the problem and reach a solution. However, each student/group must write down the solution independently, without referring to written notes or code from others. Hence, you must understand the solution well enough to discuss it yourself. In addition, each student/group must explicitly mention the names of the people with whom they collaborated.

If I suspect cheating##, I might have the student(s) come and answer questions in my office. If my suspicions are confirmed, I will consider a range of possibilities (depending on the seriousnes of the offence) that includes any/all of the following:

1. a 0 on that MP/section,
2. an F for the entire course and
3. report the student to for an academic integrity violation.

The purpose of problem sets in this class is to help you think about the material, not just give us the right answers. You are encouraged to use online resources for learning more about the material covered in class; however, you should not look for or use found solutions to questions in the problem sets. Specifically, you must not look at any code that has been created to solve the assignment, including solutions found on the internet to questions in the problem sets, code created by a student in a previous class or code created by a current classmate. (Though frankly, I seriously doubt you'll find anything, I regularly change the assignments).

ChatGPT, Github CoPilot and Other Code Generation Tools

The use of ChatGPT, GitHub CoPilot and any/all other code generation tools (that currently exist or will be developed in the future) is expressly forbidden!

If any student is found using such tools then it will be considered a violation of academic integrity and reported appropriately.

Academic Integrity

Familiarize yourself with the standards set forth in the GWU Code of Student Conduct and specifically the University’s “Guide of Academic Integrity in Online Learning Environments". If there is any question about whether an act constitutes academic misconduct, it is your responsibility to seek clarification and approval from the instructor prior to acting. When in doubt, ask, or don't do it.

Absence Policy

If you miss a class, for whatever reason, you are still responsible for that class' material. Go through the lectures, consult the scribe notes, come to office hours (in that order), and talk to your fellow students, to learn the material.

Grade Review Policy

You have one week after a grade is released to ask us questions about it and seek a correction. After the week has passed, the grade is finalized. When releasing a grade, we may also post comments where appropriate, explaining where you lost points, made mistakes, etc.

In case you are seeking a correction to the grade, you need a specific reason: e.g., your reasoning on MP 1.a was essentially correct but your written explanation, you now realize, was ambiguous; our comments say that your model had errors and I couldn't run it, but you can run it fine on your machine; etc. I cannot accommodate general requests that are a variation on "I think my grade was too low". Why do you think that? Based on our discussion, we might increase the grade, decrease it, or leave it as is.

Of course, you can stop by anytime during the term to ask questions about any part of the material. The one-week deadline applies to grade-specific questions.

Use of Electronic Course Materials and Class Recordings

Students are encouraged to use electronic course materials, including recorded class sessions, for private personal use in connection with their academic program of study. Electronic course materials and recorded class sessions must not be shared and must not be used for non-course related purposes unless express permission has been granted by the instructor. Students who impermissibly share any electronic course materials are subject to discipline under the Student Code of Conduct. Please contact the instructor if you have questions regarding what constitutes permissible or impermissible use of electronic course materials and/or recorded class sessions. Please contact Disability Support Services if you have questions or need assistance in accessing electronic course materials.

Ethical and Respectful Behavior

We expect all students to act in an respectful and ethical way, both with respect to the treatment of their peers in the classroom during discussion but also in the design and execution of their course projects. Actions should meet the expectations of ethical research and follow the norms and proper behavior of the George Washington University community. We strive for an inclusive classroom, which includes but is not limited to anti-racism, anti-sexism, accessibility, LGBTQ+ inclusivity. If you feel like you are unable to use inclusive language and behave in a non-discriminatory way, please drop the class.
