Abstract

The invention provides an attribute encryption and dynamic security layer protection method and a corresponding firewall. Intranet resources are defined as a sensing security layer, a network intermediate security layer, a service security layer and a virtual gateway node and the firewall is defined as a sensing security layer, a network intermediate security layer, a service security layer and avirtual gateway node so that one-to-one correspondence between firewalls and intranet resource network layers is realized. Security layers can be dynamically adjusted in real time according to the state of sensing equipment, a technical means of attribute encryption is introduced, attribute encryption is performed on transmission data based on attributes and attribute domains of different users, and service data of the different users are better protected.

Description

Technical field [0001] This application relates to the field of network security technology, and in particular to a protection method for attribute encryption and dynamic security layer and a corresponding firewall. Background technique [0002] The existing network architecture layering is not divided from the perspective of network security, but more from the perspective of network transmission, which will bring security risks to the network. With the rise of the Internet of Things and the Internet of Vehicles, the high-speed mobile, flexible and changeable characteristics of new networks have made the security risks brought by the layered network architecture more and more prominent. [0003] Therefore, there is an urgent need for a targeted security protection method and corresponding firewall. Summary of the invention [0004] The purpose of the present invention is to provide a protection method for attribute encryption and dynamic security layer and a corresponding firewall,...
