Ph.D. Student - Efficient Secure Multi-Party Computation
Bosch Research, Renningen, Germany
With Carbyne Stack (, Bosch is developing an open source cloud platform for computing on encrypted data using Secure Multi-party Computation (MPC). Potential use cases include Privacy-Preserving Machine Learning and Privacy-Preserving Data Analytics. For such large computations on big data, active secure MPC becomes quite expensive. Bosch Research is therefore trying to reduce the computational and communication costs of MPC by optimizing the underlying cryptographic primitives and protocols.

Thus, we are looking for a highly motivated PhD candidate with a strong background and/or interest in applied cryptography. The successful candidate will:
  • become a part of the team and advance research on MPC
  • develop novel approaches to improve the practical efficiency of actively secure MPC protocols
  • design efficient MPC protocols for diverse use-cases
  • integrate the results into our Cabyne Stack open source MPC platform
  • publish and present the results in top-tier journals and at conferences
The candidates should meet the following requirements:
  • Education: Hold an M.Sc. degree (or equivalent) with excellent grades in IT security, computer science, mathematics, or a related field
  • Experience and Knowledge: Strong background in (applied) cryptography with a particular focus on cryptographic protocols/MPC, including security models and basic security proof techniques. Good software development/programming skills and the motivation to integrate scientific results into Carbyne Stack.
  • Personality and Working Practice: Self-motivated and enthusiastic, independent, reliable, creative, and able to work in an international team with diverse background
  • Language: Fluent English language skills
