DATA PROCESSING METHOD AND APPARATUS, DEVICE, AND STORAGE MEDIUM

WIPO Patent Application WO/2022/183998

A1

Embodiments of the present application disclose a data processing method and apparatus, a device, and a storage medium. The method comprises: a first service node sending 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 in the data signature information being related to a random parameter; the random parameter being determined by the second service node on the basis of a node private key and the service data information; performing signature verification on the received data signature information on the basis of 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 the verification result set for target signature verification results satisfying a legitimate signature verification condition; and if the counted number of signatures of the target signature verification results satisfies an aggregate signature condition, performing aggregate signature on the counted data signature information. By adoption of the embodiments of the present application, network complexity of an aggregate signature can be reduced.
