• By modifying the private key and the public key setting in Boneh-Lynn-Shachams short signature shcheme, a variation of BLS short signature scheme is proposed. Based on this variation, we present a very efficient threshold signature scheme where the number of pairing computation for the signaure share verification reduces to half.
