Embodiment Construction

[0030] 1. Accompanying drawing is a kind of specific embodiment of the present invention. The implementation software architecture is as figure 1 The three-layer structure is shown: the first layer protocol

[0031] Record layer protocol format:

[0032] Protocol type (1 byte) + version number (2 bytes) + data length (2 bytes) + data content

[0033] The data content is the data packet of the second layer.

[0034] Layer 2 protocol

[0035] 1. Format of warning agreement

[0036] Warning level (1 byte) + warning description (1 byte)

[0037] 2. Handshake protocol format

[0038] Handshake type (1 byte) + handshake message data length (3 bytes) + handshake message data

[0039] Among them, the data content of the handshake message is the data packet of various handshake messages in the third layer. The serverhellodown and finished messages are special and do not conform to the protocol format. It is judged when the code parses the packet.

[0040] Layer 3 protocol

Abstract

The invention relates to a software architecture and a method for enabling an IE browser to perform communication based on a national cipher SSL protocol, relates to the field of computer information safety communication, and in particular relates to a method for enabling an IE browser to perform safety communication based on a national cipher SSL protocol. The method for enabling the IE browser to perform safety communication based on the national cipher SSL protocol is as follows: a user side needs to run national cipher protocol agent software; the IE browser and the national cipher agent software of the user side perform standard SSL protocol communication; after decrypting a data packet sent by the IE browser, the national cipher agent software re-encapsulates the data packet to form a data packet according with the national cipher SSL protocol, and forwards the data packet to a background national cipher SSL VPN; the national cipher SSL VPN decrypts data, and sends the data to an application server; and thus, data transmission is completed. According to the software architecture and the method for enabling the IE browser to perform communication based on the national cipher SSL protocol disclosed by the invention, the national cipher SSL protocol, which cannot be used in the IE browser originally, is used indirectly; on one hand, the IE browser is used just like an ordinary IE browser; on the other hand, the national cipher SSL protocol having relatively high safety degree can also be selected; and thus, data transmission is relatively safe.

Description

technical field [0001] The invention relates to the field of computer information security communication, specifically a software framework and a method for allowing IE browsers to communicate based on the national secret SSL protocol, using the method to access the background application service of the national secret SSL VPN device. Background technique [0002] The current IE browser can only use the standard SSL protocol to communicate with the background standard SSL VPN. In order to achieve the security of client access, the State Cryptography Administration has formulated the national secret SSL protocol, which makes the IE browser unable to use the existing protocol for security. communication. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the present invention provides a software architecture capable of ensuring communication security and a method for allowing IE browsers to communicate based on the national secret SSL pro...
