Frontier research
for digital asset security

Most MPC protocols are slow because they involve many steps. Latency, scalability, and availability have never been a focus. However, as more apps start requesting both high security and performance, we face a new challenge.  Our goal is to enhance MPC protocols to support high-volume, high-speed use without ever breaking.

Decentralizing key management is essential for neutral governance and secure digital assets. However, organizations may vary in their approach due to operational and regulatory factors. To meet these needs while ensuring security, we need MPC protocols that are flexible, crypto-agile, and easy to deploy in secure environments.

Blockchains try to solve trust issues but often fail because they rely on single points of failure and trusted components like coordinators and authentication systems. We address these key and signature related vulnerabilities by exploring verifiability via remote attestations, tamper-proof logs, and secure hardware among other techniques.

Running MPC protocols in FIPS 140-2 and 140-3 certified HSM is challenging, especially in resource-limited settings like satellites. Coordination and synchronization issues in MPC add to the complexity. Our goal is to ensure MPC can run safely and efficiently in any secure environment, including HSMs, CloudHSMs, TEEs, and U2F devices.

MPC protocols can be hard to differentiate and trust as there are so many of them. We are contributing to NIST to create new standards.  We've also donated our open-source libraries to Hyperledger and Linux Foundations for trust and legal clearance. Last, we're developing FIPS-140 certified MPC libraries, audited by external labs.

Dfns Labs is developing quantum-resistant threshold signatures to protect elliptic curve signature schemes from foreseeable quantum computing threats. We aim to lead in the emerging Post-Quantum TSS field. Our new protocol is supported by NIST and funded by a €2M research grant from Bpifrance.
