Communication method, system and device based on security gateway

Abstract

The invention discloses a communication method, system and device based on a security gateway, and the device comprises a communication terminal and the security gateway, and the communication terminal and the security gateway are initialized, and respectively import a corresponding digital certificate and an encryption key; the communication terminal and the security gateway perform identity authentication by using a preset digital identity certificate, and if the authentication is passed, the communication terminal and the security gateway establish a security tunnel; the communication terminal encrypts the communication data packet through the encryption key, and sends the encrypted data packet to the security gateway through the communication base station; the security gateway receivesthe encrypted data packet and judges whether the communication terminal from which the data packet comes establishes a corresponding security tunnel with the security gateway; and the security gateway processes the data packet according to the judgment result. Service pressure of a system gateway and a core network is reduced, identity authentication such as an encryption key and a digital certificate is introduced on the basis of a traditional security gateway, the security of the traditional security gateway is enhanced, and secure and accurate transmission of communication data is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of communication technology, in particular to a communication method, system and equipment based on a security gateway. Background technique [0002] With the rapid development of the Internet, ordinary communication terminals are connected to the mobile core network through fixed network broadband, which greatly expands the coverage of mobile communication signals, enabling users to carry out daily communication well through communication terminals. During the communication process, the system gateway The system gateway and the core network need to process a large number of communication data packets, which brings great business pressure to the system gateway and the core network, resulting in a significant decline in the processing capabilities of the system gateway and the core network, and even packet loss, resulting in poor communication service quality. Inadequate problems, and with the conveni...

Problems solved by technology

[0002] With the rapid development of the Internet, ordinary communication terminals are connected to the mobile core network through fixed network broadband, which greatly expands the coverage of mobile communication signals, enabling users to carry out daily communication well through communication terminals. During the communication process, the system gateway The system gateway and the core network need to process a large number of communication data packets, which brings great business pressure to the system gateway and the core network, resulting in a significant decline in the processing capabilities of the system gateway and the core network, and even packet loss, resulting in poor communication service quality. Inadequate problems, and with the convenience of Internet data transmission, and the security of transmission will also be attacked, which will easily lead to the leakage and misinformation of communication data. Therefore, we propose a communication method, system and equipment based on a security gateway for solve the above problems
