Abstract

The embodiment of the invention provides an error processing method and apparatus. The method comprises the following steps: a first terminal splits to-be-sent data into a plurality of sub data packets; assembling a head data packet, writes a total packet number, serial numbers and CRC values of the sub data packets and the CRC value of the head data packet in the head data packet, and sends the data to a second terminal, and the second terminal verifies the correctness of the head data packet according to the CRC value of the head data packet; when the first terminal receives first feedback information sent by the second terminal, the first terminal respectively sends the plurality of sub data packets to the second terminal, and the second terminal verifies the correctness and the integrity of the received sub data packets according to the total packet number and the serial numbers and the CRC values of the sub data packets. According to the error processing scheme provided by the invention, by means of the verification of the correctness of the head data packet and the correctness and the integrity of the sub data packets, the defect that the data information is unreliable in the UDP communication mode is avoided, and the correctness and the integrity of data transmission are improved.

Description

technical field [0001] The present invention relates to the fields of information security and communication technologies, in particular to an error processing method and device. Background technique [0002] The UDP communication protocol (User Datagram Protocol) is a connectionless transport layer protocol that provides transaction-oriented simple and unreliable information transmission services. UDP communication performs very well when processing small batches of data. However, as a connectionless communication method, it often leads to unreliable data transmission. The integrity and correctness of the data cannot be confirmed during data transmission. In the prior art, there is no effective and reliable error control and processing method for transmission data based on UDP communication protocol to ensure the integrity and correctness of transmission data. Therefore, the problem of realizing an effective method for error control and processing of transmitted data nee...
