Secure broadband access method, authentication method, device and system

Abstract

The invention discloses a secure broadband access method, a secure broadband access authentication method, a secure broadband access device, a secure broadband access authentication device and a secure broadband access system. The secure broadband access method comprises the following steps: performing private key signature process on user broadband account information read from a chip memory, wherein the user broadband account information comprises a user name and a password; coding the user broadband account information through the private key signature process and a user personal digital certificate read from the chip memory respectively; organizing the coded user broadband account information and the coded user personal digital certificate to form authentication information, and sending the authentication information to an access authentication system so that the access authentication system authenticates the authentication information; and under the condition that the authentication information passes the authentication of the access authentication system, receiving login success message sent by the access authentication system. The invention improves the security of the authentication information in the transmission process.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a broadband security access method, a broadband security access authentication method, a broadband security access device, a broadband security access authentication device and a broadband security access system. Background technique [0002] At present, user identity identification during the broadband access process is generally realized by the user uploading the user name and password to the access authentication system. Among the broadband access methods based on user name and password authentication, the most widely used is that the user manually enters the user name and password through the local client software, and then sends it to the access authentication system to request authentication to access the broadband. The above username and password are the broadband account information of the user. This method requires the user to install client software on a local...
