Large-scale Internet of Things service domain isolation communication method and device, electronic equipment and storage medium

Abstract

The invention belongs to the technical field of computer networks, and relates to a large-scale Internet of Things service domain isolation communication method and device, electronic equipment and a storage medium. According to the method, identity-based access control is introduced to realize logic isolation of topology and performance in an initial state of an Internet of Things service domain; meanwhile, in combination with a key management service, privacy protection is carried out on data communication service of the service domain, and end-network-cloud data full-life-cycle logic isolation, including topology isolation, performance isolation and service isolation, of the service domain of the Internet of Things is ensured. The method comprises the following steps: firstly, establishing a terminal identity at an access network position of an Internet of Things terminal by adopting an access network real source address verification technology and a real identity mechanism based on a network address; dividing fragments and allocating resources for different service domains through a software definition network slicing mechanism in the management domain to realize topology and performance isolation of the different service domains; and finally, realizing service isolation based on an access control mechanism, and realizing data encryption by using symmetric key exchange.

Description

technical field [0001] The present application belongs to the technical field of computer networks, and in particular, relates to a large-scale Internet of Things service domain isolation communication method, device, electronic equipment, and storage medium. Background technique [0002] With the rapid development and wide application of computing technology and network technology, while the Internet of Everything brings great convenience and development to society and economy, its huge user resources, number of devices and its own vulnerability have also become the first choice for security attacks. How to adopt effective technical means in an open and shared network to ensure that the service domains of the Internet of Things are isolated from each other in the initial state, so as to protect the data security and privacy in the communication process of different service domains, has become an important issue to be solved in the security research of the Internet of Things....
