Count Me In! Extendability for Threshold Ring Signatures
Ring signatures enable a signer to sign a message on behalf of a group anonymously, without revealing her identity. Similarly, threshold ring signatures allow several signers to sign the same message on behalf of a group; while the combined signature reveals that some threshold t of the group members signed the message, it does not leak anything else about the signers’ identities.
