Private network cross-network authentication method and device

Abstract

The invention discloses a private network cross-network authentication method and a private network cross-network authentication device, relates to the technical field of communication and are used for safely and effectively performing user identity authentication among a plurality of private networks, improving the efficiency of performing quick authentication among different networks by a user and improving the service experience of the user. The method comprises the steps: under the condition that an initial service network of the electronic equipment is a first private network, if the electronic equipment is located in a service range of a second private network, enabling the electronic equipment to send a registration query request to the second private network; after the second private network receives a registration query request sent by the electronic equipment, sending a target message to the first private network through the block chain cross-network authentication gateway platform; after the first private network receives the target message, acquiring subscription information and identity registration information of the electronic equipment according to the target message, and verifying whether the identity of the electronic equipment is legal or not; and when the first private network determines that the identity of the electronic equipment is legal, sending a response message to the second private network through the block chain cross-network authentication gateway platform, and completing cross-network authentication of the private network.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a private network cross-network authentication method and device. Background technique [0002] Due to the data security and privacy requirements of the network, an independent 5G private network needs to be deployed in industrial parks, large office parks, campuses, shopping malls and other scenarios. The internal network of the private network is isolated from the external network to achieve independent management of internal networks and data And maintenance. [0003] However, due to the complete isolation between the private network and the public network, and between the private network and the private network, when non-locally registered private network users enter the network area, they will face problems such as being unable to obtain network services, or unable to perform network registration efficiently and quickly. For example, public network users use private ...
