Internet-of-things safe cloud platform based on deep data traffic perception

Abstract

The invention discloses an Internet-of-things safe cloud platform based on deep data traffic perception. The Internet-of-things safe cloud platform comprises a functional unit arranged between an Internet-of-things connecting layer and a service application layer, wherein the functional unit comprises a deep engine perception engine which is used for identifying service attribute of a current datapacket, and extracts the characteristic parameter of a characteristic field according to the service kind for performing classification statistics analysis. Particularly the functional unit performsthe following steps of 1, extracting key information of an IP layer, a transmission layer and partial application layer of network data traffic, matching an application characteristic database, and identifying the protocol type of the current data traffic; 2, in the current protocol type, extracting the service data characteristic of the network traffic flow, and constructing a quantitative distribution model of a data load; and 3, based on the service data characteristic, identifying the characteristic field of an unknown traffic data packet and extracting the field value of the characteristic field, recording the change amount and outputting. The Internet-of-things safe cloud platform has advantages of increasing a classification method based on key content identification, realizing deepanalysis to each behavior parameter of Internet-of-things data traffic and effectively ensuring network safety of the Internet-of-things system.

Description

technical field [0001] The invention belongs to the technical field of network security protection, and relates to an Internet of Things security cloud platform based on deep traffic perception. Background technique [0002] With the rapid development of the Internet of Things, security issues have become a pain point in industrial development. For example, hackers can launch large-scale denial-of-service attacks by invading and controlling IoT devices with weak security protection, causing varying degrees of impact in multiple countries. The development of the Internet of Things is a national strategy for my country to seize the commanding heights of a new round of economic and technological development. Without security, the development of the Internet of Things industry will be accompanied by huge risks. The Internet of Things is an extension of the Internet, so the security of the Internet of Things is also an extension of Internet security. However, the security of th...
