Abstract:

An anti-attack data transmission method and an apparatus thereof are provided. The method includes obtaining a communication protocol message to be transmitted; performing an anti-attack pre-processing for data on information bit(s) located at a message header in the communication protocol message, and generating processing information; storing the processing information in extension bit(s) at the message header of the communication protocol message to obtain a converted communication protocol message, wherein the message header of the communication protocol message includes the information bit(s) and the extension bit(s); and sending the converted communication protocol message to a receiving device. The present disclosure solves the problem of false negatives associated with normally transmitted data flow caused by existing anti-attack methods.
