Thesis Work on Encrypted Control

At ABB, we help industries outrun - leaner and cleaner. Here, progress is an expectation - for you, your team, and the world. As a global market leader, we’ll give you what you need to make it happen. It won’t always be easy, growing takes grit. But at ABB, you’ll never run alone. Run what runs the world.

This Position reports to:

R&D Team Lead

Your Role And Responsibilities Recent advances in cryptography enable computations to be performed directly on encrypted data.

This opens the possibility of cloud-based controllers that never access the underlying process measurements or control commands in unencrypted form.

Such technology could enable secure optimization and control across organizational boundaries while preserving data confidentiality.

Details:

• Period: January 2027-June 2027, 5 months
• Number of credits: 30 ECTS
• Number of students for this thesis work: 1
• Location: ABB Corporate Research (Västerås)

The thesis will explore feedback control and optimization using encrypted signals in cloud-based control systems.

Goals:

• Implement a controller operating on encrypted data for a lab-scale system, such as a ball-and-beam setup.
• Quantify the trade-offs between privacy, computational cost, communication latency, and control performance

Qualifications For The Role

• Background in automatic control, optimization or a related field.
• Experience with simulation and programming (e.g., MATLAB/Simulink or Python).
• Ability to work independently with scientific literature and hands-on experiments.
• No prior knowledge of cryptography is required.
