Privacy and Scaling Explorations

This post was written by PSE researcher Miha Stopar. There's no doubt that lattice-based cryptography is currently the most promising branch of post-quantum cryptography. Not only is it highly performant and versatile, it also provides the only known technique to achieve fully homomorphic encryption. One reason lattice-based cryptography is so fast is that it can be heavily vectorized. This contrasts noticeably with isogeny-based cryptography, which offers far fewer opportunities for par...

This post was authored by the Circom MPC research team. Circom-MPC is a PSE Research project that enables the use of the Circom language to develop MPC applications. In this project, we envisioned MPC as a broader paradigm, where MPC serves as an umbrella for generic techniques such as Zero-Knowledge Proof, Garbled Circuit, Secret-Sharing, or Fully Homomorphic Encryption. Throughout this research the team produced some valuable resources and insights, including:Implementation of circom-2-arit...
