Communication interface for network security protection and communication method

Abstract

The invention discloses a communication interface for network security protection and a communication method. The communication interface is used for connecting electronic equipment to a network and comprises an internal terminal connected to the electronic equipment, an external terminal connected to the network in a wired or wireless manner, an ARINC664P7 bus which is connected with the internal terminal and the external terminal to transmit data, and an ARINC429 bus which is connected with the internal terminal and the external terminal to transmit control information related to the data.

Description

technical field [0001] The invention relates to the communication field, in particular to a communication interface and a communication method for network security. Background technique [0002] With the development of modern communication technology, data transmission between various devices has become more and more common. At the same time, data security is becoming more and more important. For example, when a device or an internal network communicates with an external public network, it is often hoped that the device or the internal network will not be polluted by intentional or unintentional data from the external public network. A typical application scenario is the on-board data network of an aircraft. In the past, the airborne data network of the traditional aircraft and the external network were physically isolated from each other, there was no data communication between them, and there was no wired and wireless communication channel between the two networks. Ther...

[0005] b) Using the ARINC429 bus interface, based on the determinism of the ARINC429 interface, the communication security can be guaranteed while the data transmission of the internal and external networks is carried out. Requirements for the transmission of large amounts of data

[0006] c) ARINC664P7 bus interface is adopted. At present, this communication interface can provide large data communication between internal and external networks. However, in order to ensure the security of the internal network and isolate it from the external network, it is necessary to formulate a more comprehensive and highly reliable security strategy at each network layer and protective measures, the design is more complicated, and the airworthiness verification is also more difficult
