Abstract: Embodiments of the present disclosure relate to the field of communication transmission, and in particular, to a network anti-replay method and apparatus, an electronic device, and a storage medium. The network anti-replay method includes: according to a current packet number of a currently received data packet, determining a section to which the current packet number belongs in a replay window, with the replay window being divided into a plurality of sections, and each of the plurality of sections being configured to record packet numbers of L received data packets which belong to the section; and L being smaller than T, and T being a total number of packet numbers belonging to the section; and in a case where the current packet number is not coincident with packet numbers recorded in the determined section to which the current packet number belongs and the current packet number is not coincident with packet numbers of recently received N historical data packets, performing integrity authentication on the currently received data packet, with N being a natural number greater than 1.
