Blockchain copyright storage protocol based on short verifiable ring signature
In the existing blockchain copyright storage systems,various ring signatures occupied too much storage space,and the efficiency of the data consensus algorithm needed to be improved.The public keys of the ring members were accumulated using a dynamic accumulator in order to solve these issues.Various algorithms were then designed,including initialization,system selection,key generation,signature generation,and signature verification,to create an ID-based short verifiable ring signature scheme with multiple private key generators(PKG).The credit threshold was set for the primary node selection,the maximum number of nodes allowed to participate in the consensus was reduced,and the existing consortium blockchain consensus algorithm was improved.Using the new ring signature scheme constructed and the improved consensus algorithm,a new blockchain copyright storage protocol was proposed.Finally,the unforgeability and anonymity of the signature scheme were formally proved.The consensus algorithm and fault tolerance of the system were assessed experimentally,and the computational effectiveness and storage capacity of the signature scheme were examined and simulated.The results show that the proposed protocol saves the signature time and storage space,and improves the consensus efficiency and fault tolerance.
