Secret Sharing Scheme

Definition ∞ A secret sharing scheme is a cryptographic method that divides a secret into multiple parts, known as shares, and distributes them among several participants. The original secret can only be reconstructed when a predefined minimum number of these shares are combined. No individual share or subset below the threshold reveals any information about the secret. This system provides a robust way to protect sensitive information by decentralizing its custody.
Context ∞ Secret sharing schemes are relevant in digital asset security for applications such as multi-party computation, secure key management, and decentralized autonomous organizations. News often covers their use in enhancing the resilience of cryptographic systems against single points of failure. The ongoing development involves optimizing these schemes for efficiency and integrating them into more user-friendly security solutions for digital assets.
