Access control method and device for terminal equipment

Abstract

The invention provides an access control method and device for terminal equipment. The method comprises the following steps: judging whether the terminal equipment is new equipment or not according to a connection request of the terminal equipment; if not, obtaining a pre-stored access rejection frequency of the terminal equipment; judging whether the number of times of refusing to access is within a preset first threshold range, and if not, refusing to access the terminal equipment; if yes, calculating the authentication credibility of the current connection of the terminal equipment based on a pre-created authentication credibility model; and if the authentication credibility is within a preset second threshold range, allowing the terminal equipment to access, otherwise, refusing the terminal equipment to access. The method and the device can solve the problems that in the prior art, due to the fact that the number of terminal devices connected with a communication network is large and the sparsity of the connected devices is large, detection of the terminal devices with malicious connection requests is difficult, and an effective access control method is lacked to conduct access control on the devices with the connection requests.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to a terminal equipment access control method and device. Background technique [0002] In a communication network, network nodes usually need to connect a large number of terminal devices, and terminal devices often join or leave the communication network dynamically. When a new terminal device connects (or leaves) the communication network, the network node needs to ensure that the registered terminal Uninterrupted service to devices also requires limiting or denying service requests from malicious or compromised end devices. Once a malicious terminal accesses the communication network, it may endanger the security of the connected network nodes or even the entire communication network. [0003] However, due to the large number of terminal devices connected to the communication network and the sparseness of connected devices, it is difficult to detect terminal devices wi...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a terminal device access control method and device for the above-mentioned deficiencies of the prior art, to solve the problems in the prior art due to the large number of terminal devices connected to the communication network and the difficulty of connecting devices. Sparseness makes it difficult to detect terminal devices with malicious connection requests, and lacks an effective access control method to control the access of devices with connection requests
