Public keys and sub signatures of the plurality of signature parties are obtained, and a sub signature of the signature party is based on the random number of the signature party, the message abstract, and private keys of the plurality of signature parties. An aggregation public key is generated according to the public keys of the plurality of signature parties, and a length of the aggregation public key is less than a length of the plurality of public keys after splicing. An aggregation signature is generated according to a sum value of the plurality of sub signatures and the message abstract.
