[0069] The connection login establishment process between the network access user terminal 11 and the network access terminal 13 includes as follows: figure 2 Steps S11-S16 are shown.

[0070] The first step (S11) of the terminal connection performed by the network access user terminal in order to log in to the network and use the network service is to listen to the scheduled broadcast of the network access terminal. The microprocessor module 132 in the network access terminal 13 takes out configuration parameters such as the broadcast time interval, the key perturbation strength 212 and the current system time from the configuration memory 134, and determines a period of time as the effective network access time window 213 according to the current network traffic volume, Then, the scheduled broadcast message is broadcast in plain text through the data transceiver 131 . The content of the regular broadcast message 21 includes current system time information 211 , key perturb...

[0078] The improvement to the first embodiment of the connection login establishment process between the network user terminal 11 and the network access terminal 13 is as follows: figure 2 Steps S11-S16 are shown.

[0079] The first step (S11) of the terminal connection performed by the network access user terminal in order to log in to the network and use the network service is to listen to the scheduled broadcast of the network access terminal. The microprocessor module 132 in the network access terminal 13 periodically fetches configuration parameters such as the broadcast time interval, the key perturbation strength 212 and the current system time from the configuration memory 134, and determines a period of time according to the current network traffic volume as the effective network access time Window 213 generates a random number y according to the configuration of the network access terminal configuration memory 134 (such as the codeword length), and then further gene...

Abstract

The invention discloses a method for identifying physical uniqueness of blocking-attacking resistant in-net terminal and a terminal access authentication system, which belongs to a method for a user terminal to access a communication service network and a system realizing the same. The invention is characterized in that the method divides the exchanging process of bi-direction messages for determining the legal identity of the user terminal into the following six steps: a network access terminal broadcasts the turbulence intensity of keys and an effective in-net time window; the in-net user terminal initiates an in-net request at an appointed time window; the network access terminal sends a terminal login token in a ciphertext mode; the in-net user terminal attempts to decode a response message; the in-let user terminal passes back terminal login token identifying information to the network access terminal; and the network access terminal verifies the terminal login token identifying information.

Description

technical field [0001] The invention belongs to a login method for a user terminal to access a communication service network and an implementation system thereof, in particular to a method for establishing a network access user terminal connection and an implementation system for initial authentication of terminal access for resisting blocking attacks. Background technique [0002] With the development of network technology and the popularization of network communication, network security has increasingly become the focus of people's attention. The current security threats to the network mainly come from hacker attacks, network defects, software loopholes, and lack of management. Blocking attacks initiated by network hackers or computer viruses are one of the more difficult to prevent. [0003] "Blocking attack" is also called "denial of service attack". It is a kind of network attack: when the communication network is attacked by this form, it partially or completely lose...
