Abstract
The invention discloses an inter-multiple-node data integral transmission system. According to the system, firstly, data to be transmitted is segmented; the data to be transmitted is transmitted from the first segment; after intermediate nodes receive the first segment of data, data verification information of the segment of data is judged; under the situation that the data verification information of the segment of data accords with the condition, if the intermediate nodes receive an integrity verification code of the segment in time tolerance, the integrity verification code of the segment is recorded; other segments of data are repeatedly subjected to integrity verification until the integrity verification codes of all the segments are recorded; the intermediate nodes generate self-verification texts and data content copies; the intermediate nodes transmits the self-verification texts and the data to a target node segment by segment and the target node compares received data contents and verification results, so that whether the data is integral or not can be clearly known.
