Threshold Cryptography

Definition

A cryptographic system that requires a minimum number of participants (a threshold) to cooperate to perform a cryptographic operation, such as generating a key or signing a message. This approach enhances security by distributing sensitive operations across multiple parties, preventing single points of failure or compromise. It is fundamental for secure multi-party computation and key management in decentralized systems.
