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.
