Introduction to Threshold Signatures

A group of parties can create a digital signature in such a way that none of the parties have access to the secret needed to create the signature. Only a quorum (a part of parties) participates in signing. The signature looks always the same, and it doesn’t change whatever you sign with it. The public key is a semblance of your name in a document signed with a common signature. This information about you is publicly known. On the other hand, only you should know the private key. For authentication, one should have the public key used to have the signer’s public signature, the signed message, and the public identifier.
