 Threshold cryptosystem

A threshold cryptosystem is a cryptographic system that allows a secret (such as a private key) to be divided into multiple shares in such a way that only a certain number of these shares (the threshold) is required to reconstruct the secret. This approach enhances security by distributing the trust among multiple parties, ensuring that no single party can access the entire secret by themselves. ### Key Concepts: 1. **Secret Sharing**: The basic idea behind threshold cryptography.
