Implementing Efficient Secure Computation


We are offering Hiwi jobs. The number of working hours is flexible and ranges from 20 to 82 hours per month starting as soon as possible.

Motivation & Goal

Secure computation allows mutually distrusting parties to jointly compute a function on their input data without revealing anything but the result. It can be employed on a variety of hardware platforms, ranging from mobile phones to high-end servers, and has a high number of applications, including the discovery of common contacts, genomic sequencing, or the secure processing of data in the cloud. Correspondingly, possible challenges for an applicant are wide-spread and include but are not limited to:

  • Implementing new protocol designs in C/C++, as well as evaluating them and comparing them to prior art
  • Running experiments for determining protocol parameters and failure probabilities on the Lichtenberg High Performance Computer (HHLR)
  • Maintaining and extending our ABY framework for efficient mixed-protocol secure two-party computation

The results emerging from this work are essential contributions to research papers that will be published at international top conferences.


  • Good programming skills in C/C++
  • At least basic knowledge of cryptography
  • High motivation and creativity + ability to work independently
  • Flexible working hours
  • Experience with reading research papers is beneficial
  • Knowledge of the English language goes without saying
