= Proactive secret sharing
{wiki=Proactive_secret_sharing}
Proactive secret sharing is an advanced cryptographic technique designed to enhance the security and reliability of secret sharing schemes. In traditional secret sharing, a secret (such as a cryptographic key) is divided into multiple shares and distributed among participants, where a certain threshold of these shares is required to reconstruct the secret. While effective, traditional schemes can be vulnerable to certain attacks, such as when a participant's share is compromised or when all shares are static over time.
