Threshold Signature

Threshold Signature is a form of digital signature where a group of participants each hold a share of a private key. A predefined number of these participants (the threshold) must collaborate to produce a valid signature, while a single participant alone cannot do so.

How does it work?

  1. Key Generation: A master private key is split into several shares using a secret sharing scheme.

  2. Signature Creation: A subset of participants (meeting the threshold) each use their private key share to generate partial signatures.

  3. Signature Aggregation: These partial signatures are combined to form a complete signature, which can be verified with the corresponding public key.

Benefits

  • Enhanced Security: No single point of failure since the private key is never fully reconstructed.

  • Fault Tolerance: The system remains operational even if some participants are unavailable or compromised.

  • Scalability: Efficient in large networks, reducing the burden on any single participant.

  • Collusion Resistance: Higher resistance to collusion attacks, as an attacker needs multiple key shares to forge a signature.

Threshold Signatures improve the security and privacy of digital transactions. They foster a more inclusive and privacy-respecting digital environment.
