An external network access authentication system and authentication method based on hardware access card

Abstract

An external network access authentication system and authentication method based on a hardware access card, the external network access authentication system based on a hardware access card includes: an authentication server connected to an internal network uses a hardware access card as a link to an external network The hardware access card is externally connected to the client through the external network, and the hardware access card is internally connected to the CPU through the peripheral bus, and the CPU is connected to the internal network through the network card; the client and the hardware access card must pass two-way authentication; The connection between the external network and the internal network uses the hardware access card as the security boundary. The present invention uses a hardware access card as a peripheral device connected to the external network, and the connection between the external network and the internal network uses the hardware access card as a security boundary, and the interface is simple and clear, so that the authentication server is more strictly isolated from the network where the client is located , which avoids the risk of the authentication server being invaded, and can work together with other existing servers, and has good applicability.

Description

technical field [0001] The invention relates to an external network and an internal network interconnection technology, in particular to an external network access authentication system and authentication method based on a hardware access card, belonging to the technical field of data communication. Background technique [0002] Under the background of the rapid development of network communication technology, network information and various applications are becoming more and more popular. This article is referred to as intranet for short; extranet: Internet, this article is referred to as extranet for short, such as the Internet). The internal network is relatively safe, and will neither be attacked by hackers from the external network nor leak secrets. However, because the external network is full of many unsafe factors, such as: malicious attacks by hackers, virus infection, etc., it always threatens the security of the internal network. Users need to access the intrane...
