Abstract

The invention discloses a safe processing method of a network protocol data packet. The method comprises the following steps of receiving a network protocol data packet P1 from a client; analyzing the network protocol data packet P1; determining whether the analyzed data packet contains a keyword identification of an application layer protocol; if the keyword identification is found, determining whether a packet header content of the network protocol data packet P1 contains a predetermined keyword; and if the predetermined keyword exists, according to a type of the predetermined keyword, carrying out corresponding operation on a content in a packet body of the network protocol data packet P1 and sending a generated network protocol data packet P2 after the operation to a client. In the invention, through safely transmitting the data packet to a remote server, network attacks of different layers can be withstood so that safety of data packet transmission is increased; in addition, different types of the data packets can be distinguished, signature message integrity is verified, and an identity of a sender is confirmed so that a repudiation condition in a transaction is prevented.

Description

Technical field [0001] The present invention belongs to the field of information security technology and Internet communication, and more specifically, relates to a method and system for safely processing network protocol data packets. Background technique [0002] With the continuous improvement of informatization, various government departments or enterprises have deployed a large number of business systems on the Internet, and exchange business data with other branches or partners through the Internet. These business data are government The confidentiality, authenticity, integrity and non-repudiation of important digital assets of departments or enterprises and institutions need to be guaranteed during the informatization construction process. [0003] Among these business data, due to security considerations, they often cannot be sent directly to the remote server. They need to be processed by the Internet gateway device before they can be finally sent to the remote server, rec...
