PPPoE dialing method

Abstract

The invention discloses a PPPoE (Point-to-Point Protocol over Ethernet) dialing method. The method comprises the following steps: selecting an AC (Access Controller) server with the highest priority for dialing; a client starts to establish a data communication link, a plurality of disguised account passwords are produced on the basis of a real account password when the client dials, the disguised account passwords are firstly used for authentication, and the real account password participates in authentication in a certain random process; according to the invention, PPPoE dialing is carried out by using the disguised account password, the network environment is detected, the protection of the account password is enhanced, and the difficulty of acquiring the real account password by an attacker is increased.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular a method of PPPoE dial. Background technique [0002] PPPoE (Point-to-Point Protocol over Ethernet) is a tunnel protocol encapsulated in the Ethernet framework in 1999, published in 1999. PPPoE is a transmission method that utilizes an Ethernet to send a PPP package, as well as techniques for establishing multiple PPP connections on the same Ethernet. PPPoE integrates the characteristics of Ethernet and PPP connections. By using PPPoE to establish a network connection, you can centrally manage network access, facilitate operators to bill, bandwidth allocation, access control, etc., PPPoE can also prevent ARP attacks in the LAN. PPPoE's above has solved the actual application problem of operators. It has been recognized by operators. It is compatible with devices in existing networks, which makes PPPoE to get extensive in operators. use. [0003] The PPPoE workflow is divid...

The scheme proposed in this invention is based on the fact that the dial-up host can communicate with the host in the cloud before the dial-up is successful, so as to achieve the purpose of verifying the PPPoE server in the cloud, but before the dial-up is successful, the host can only communicate through the mac, causing this The first method is difficult to implement; secondly, the disguised PPPoE server can also disguise its own MAC and host name as a normal AC host, which increases the difficulty of identifying illegal AC servers on the cloud

In the article "Deciphering the Ancient and Killing Router Attack Technique: From Sniffing PPPoE to Hidden Backdoor", it is proposed to disable the PAP protocol or scramble the account password during authentication to increase the difficulty of the pppoe account password. This solution needs to be based on The scrambling rules for account passwords design a new authentication method, which is not universal for operators
