Device security access system and method for digital home network

Abstract

The invention belongs to the technical field of the Internet of Things, and discloses a device security access system and method for a digital home network, and a device authenticator, which are used for security authentication of all devices. The present invention adds a device authenticator when building a digital home network, and performs security authentication on all devices, including control points and sensor devices, and uses control points as devices for secure access to prevent malicious access of external devices; adopts two-factor Authentication method; the authentication of the control node is changed to the authentication server authentication; the device authentication server is introduced as a new UPnP device, named UPSer. The authentication and registration process for devices has changed.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, and in particular relates to a device security access system and method for a digital home network. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: The rise of the Internet of Things technology has drawn widespread attention to the digital home, and the digital home has become a research hotspot in today's society. With the gradual promotion of intelligent home appliances in the home, people's requirements for building a digital home network continue to increase, so it is of great significance to improve the performance of the digital home; among them, building a digital home network with good performance is one of the key points. The service discovery protocol can effectively solve the problem of how to automatically and effectively manage the networking of devices. UPnP technology is now widely used in digital hom...

Problems solved by technology

[0003] To sum up, the problem existing in the prior art is: although UPnP has defined equipment security service, but this scheme exists On the downside: Devices (including control points) that implement device security services will need to support some basic encryption algorithms and signature algorithms to implement encryption and authentication in the communication process. For devices with low or no computing power, this solution is not suitable. Supported; the control node is a device, which is not certified by the scheme
