Security gateway device

Abstract

The invention relates to a security gateway device, adopting a new structural design and introducing a hardware encryption verification mode. A wired signal switching module and a wireless signal switching module are respectively used for wired access and wireless access to perform physical blocking, a password verification architecture combined with the password control module and the password matching module is introduced to perform password verification for wired access and wireless access respectively, one-way communication links are adopted for the password verification architecture, andall the hardware connections between the connected network are completely eliminated. Thus, based on the correct password verification operation, the wired signal switching module and the wireless signal switching module are correspondingly controlled, and the communication between the connected terminal and the connected network is completed, thereby effectively improving the security of the designed gateway device in actual use.

Description

technical field [0001] The invention relates to a safe gateway device, which belongs to the technical field of network equipment. Background technique [0002] Network devices are devices used for network connection. Among them, with the continuous development of the network, various network layouts emerge as the times require, and gateway devices are particularly important. Gateways are also called network connectors, protocol converters, and gateways. It is the most complicated network interconnection device to realize network interconnection above the network layer, and it is only used for the interconnection of two networks with different high-level protocols. A gateway can be used for both wide area network interconnection and local area network interconnection. A gateway is a computer system or device that acts as a conversion task. It is used between different communication protocols, data formats or languages, and even systems with completely different architectures....

Problems solved by technology

A gateway can be used for both wide area network interconnection and local area network interconnection. A gateway is a computer system or device that acts as a conversion task. It is used between different communication protocols, data formats or languages, and even systems with completely different architectures. Between the two systems, the gateway of the existing technology has developed quite maturely in terms of network technology, but in practical applications, there are still some deficiencies. The gateway equipment is equipped with wired access and wireless access. In the existing terminal access operation, the wireless access method can be authenticated by binding the password + MAC address, but usually, the wired access usually only uses the binding of the MAC address for authentication, or uses Software-based password verification method, but this kind of password method is prone to loopholes, and there are still potential security risks
