Van Horn to Fuchsia: Capability-based Access Control
Overview
Capabilities as an access control paradigm have been around for nearly six decades. Still, until recently, they were a little-known access control primitive and not deployed in end-user devices. However, they recently re-emerged with the advent of CHERI and Google Fuchsia. This seminar will discuss how capability systems evolved over the decades and which properties could benefit modern systems. Specifically, mobile, appified systems like Android and iOS.
Since capabilities are a long-established area of research, the selected papers include current and historical works.

Course structure and grading
The course is structured as a standard seminar. Every week, one student will present an assigned paper for discussion. Before this, all students are expected to read the handed-out papers carefully and prepare a list of discussion questions. Additionally, every student will write a short report on their assigned papers, in which the presentation should be elaborated in more detail and potentially include the discussion results. Grading will be based on presentations (30%), the report (50%), and general in-class discussion participation (20%). Please note that we expect active participation in the discussions!
Registration and prerequisites
There are no formal prerequisites. However, students must be familiar with the basics of access control and operating system security to understand the concepts from the literature. For example, by passing the Foundations of Cybersecurity lecture or the Core Lecture Security.
Registration is handled via the central registration system of the UdS.
