PVSS Mechanism

Definition

A PVSS (Publicly Verifiable Secret Sharing) mechanism is a cryptographic protocol that allows a secret to be divided into multiple shares, distributed among participants, such that the secret can only be reconstructed when a sufficient number of shares are combined. Critically, each share’s validity can be publicly verified without revealing the secret itself. This mechanism is crucial for secure key management, threshold cryptography, and decentralized randomness generation in blockchain systems. It ensures robustness against dishonest participants.
