Abstract: A data processing method includes: transmitting, by a first service node, service data information to a second service node, so that the second service node obtains data signature information; a first key parameter and a second key parameter that are both related to a random parameter; the random parameter being determined by the second service node based on a node private key and the service data information; performing signature verification on the received data signature information based on the first key parameter and the second key parameter, and adding a signature verification result obtained after signature verification to a verification result set; searching for a target signature verification result that satisfies a valid verification condition from the verification result set; and performing aggregate signature on the data signature information obtained after calculation when a quantity of signatures of the target signature verification result satisfies an aggregate signature condition.
