Abstract: With the development of informatization, the digital multi-signature mixed with sequential and broadcast structures has become a research hotspot. This paper firstly analyzed a common mixed signature structure, and then presented an algorithm with unitary structure, which is more effective and secure. For this algorithm, the broadcasting was regarded as dummy sequential one, and led a Center of Signature and Verification (CSV) into operation. The security and efficiency of the algorithm is proved excellent through contradistinctive test, so the algorithm can resolve digital multi-signature of multifarious multistructure.
