Secret Sharing

Definition ∞ Secret sharing is a cryptographic technique that divides a secret piece of information into multiple parts, called shares. These shares are then distributed among different parties, and a specified minimum number of shares are required to reconstruct the original secret. This method ensures that no single party possesses the complete secret, thereby enhancing security.
Context ∞ Secret sharing is increasingly relevant in the digital asset management and decentralized finance sectors for securing private keys and sensitive data. News articles may report on its application in multi-signature wallets, secure key recovery mechanisms, or distributed custodianship solutions. The focus is often on how secret sharing protocols bolster security against single points of failure and unauthorized access.
