Real World MPC (RWMPC 2025) Workshop

Tuesday, March 25, 2025

Co-located with Real World Crypto 2025

Organized by the MPC Alliance In Cooperation with IACR

The Real World MPC (RWMPC 2025) Workshop, which will take place on Tuesday, March 25, 2025 co-located with Real World Cryptography 2025 in Sofia, Bulgaria, seeks submissions for contributed talks on real-world applications of secure multiparty computation (MPC). The workshop will not have proceedings; hence, submissions can be based on work in progress, papers in submission, or papers published elsewhere. Areas of interest broadly include:

  • Novel protocols/paradigms for MPC

  • Real-world deployments of MPC

  • MPC standardization efforts

  • Cryptanalysis of real-world MPC protocols

  • Programming languages, software frameworks, and compilers for MPC

  • Formal verification of MPC implementations

  • Real-world security of MPC implementations and/or deployments

  • Real-world studies of the economic impacts of MPC

  • Legal and policy implications of MPC 

Work on theoretical MPC protocols that have not been (or are not expected to be) deployed is outside the scope of the workshop. The RWMPC 2025 program committee will select talks with the aim of constructing a balanced program that will be of high interest to the audience. The workshop will also include talks by invited speakers.
