Broadband access method, terminal, server and system for performing secondary authentication

Abstract

The invention discloses a broadband access method, terminal, server and system for performing secondary authentication. The broadband access method for performing the secondary authentication comprises the steps: an authentication server performs first authentication according to preset account and passwords of a terminal; if the first authentication succeeds, configuration information is transmitted to a broadband remote access server (BRAS), at which the terminal is located; the BRAS allocates an IP address to the terminal and transmits the configuration information, and the terminal accesses a network; broadband line information of the terminal matches real account and passwords of a user, and the real account and passwords are encrypted by keys and then are transmitted to the terminal, and secondary authentication is performed; the terminal re-dials according to the real account and passwords, and after an authentication server passes the secondary authentication, normal broadband access is performed. According to the broadband access method, terminal, server and system for performing the secondary authentication, the original mode of configuring broadband account and passwords by the user is changed to be a mode of automatic configuration on a network side; therefore, configuration operations are simplified, and the security is improved.

Description

technical field [0001] The invention belongs to the user authentication technology in the field of computer and data communication, and in particular relates to a broadband access method, a terminal, a server and a system for secondary authentication using broadband line information. Background technique [0002] The broadband Internet access method currently provided by the network service provider is mainly the asymmetric digital loop (ADSL) method, and the access technology uses the Ethernet-based PPP (PPPoE) authentication method as its main authentication method. The PPPoE authentication method is that the user terminal submits a pair of account / password or challenge value to the authentication, authentication and accounting server (AAA) on the network side through the Password Authentication Protocol (PAP) or the Challenge Handshake Authentication Protocol (CHAP) when dialing up, and passes the network After the user side authenticates the account / password, the user au...

Problems solved by technology

[0003] In actual use, considering the need to protect the security of user accounts, the passwords provided by network service providers to users when users open broadband accounts are often complex and difficult to remember, and users need to reconfigure dial-up accounts when they need to replace dial-up terminals such as routers. When using a broadband password, it is usually difficult to find a paper business form with a broadband password printed when opening a broadband
