| Abstract: | A new multi-signature scheme was proposed with the extension of the direct anonymous attestation (DAA) protocol supported
by trusted computing (TC) technology. Analysis and simulation results show that the signer’s privacy is well protected with
dynamic anonymity, the public key and signatures have length independent of the number of signature members, new signers are
allowed to join the signature without modifying the public key, and attacks caused by secret key dumping or leaking can be
avoided.
