The present invention provides a method and apparatus for verifying data blocks transmitted over a network. First of all, the network server aided verification of the data block, by one or more auxiliary check value, and the one or more auxiliary check value will be or is sent to or have to download one or more user equipment of the data block; then, the user terminal equipment access to one or more a check of the data block corresponding value from the network, and re verification of the data block, get one or more local check value, finally will be the one or more auxiliary check value is compared with the one or more local check value, to determine the data block whether it is right. By adopting the method and the device of the invention, the correctness of the network transmission data block can be quickly and effectively verified, and the invention is especially suitable for the authentication of the network transmission data based on the P2P protocol.
