Non-Interactive Distributed Key Generation (DKG) is a cryptographic protocol allowing multiple parties to jointly generate a shared secret key without direct communication during the process. Each participant independently computes their key share, and the final key is derived from these components. This method enhances security by removing the need for real-time coordination.
Context
Non-interactive DKG protocols are crucial for enhancing the security and decentralization of various cryptographic systems, including threshold signature schemes and secure multi-party computation. Their development is particularly relevant for blockchain applications requiring robust, non-custodial key management solutions. Research continues to optimize their efficiency and security properties.
A Distributed Verifiable Random Function combines threshold cryptography and zk-SNARKs to generate public, unpredictable, and bias-resistant randomness.
