Coding for Privacy and Security in Federated Learning

Beschreibung

In this internship, the student will read and summarize the recent progress on codes for privacy and security in federated learning.

Depending on the student's progress, we can investigate new ideas for security in private federated learning that improve upon the state0of0the-art.

Access Cost of Code Conversion

Beschreibung

In large-scale distributed storage systems, data is stored on multiple servers. Erasure codes (mostly linear MDS codes) are used to protect the data against disk and server failures. Since the failure rates can change over time, it is beneficial to convert the code parameters (code length and code dimension) at a later point in time. This is called the code conversion problem.

Recent work has studied the access cost of the code conversion problem [1-3], which is the number of servers that needs to be accessed to perform the code conversion. The papers derive fundamental limits of the access cost and propose an achievable encoding scheme. The problem is first studied for the "merge regime" [1,2], and then generalized to other parameter regimes [3].

The goal of the seminar is to understand the code conversion problem, the fundamental limits on access cost, and how to construct suitable codes for different parameter regimes. The findings shall be presented in a written report and a scientific presentation.
