Information hiding based safety energy-saving communication method of wireless image sensor network

Abstract

The invention provides a digital image information hiding based safety energy-saving communication method of a wireless multi-media sensor network aiming at the communication problems in an existing wireless multi-media sensor network. A node is divided into a data acquisition module, a data processing module, a wireless communication module and a power module, the power module is used for supplying power to the whole node and controlling sleep and operation of the node, and a digital image information hiding algorithm which is safe, lightweight, transparent and high in robustness is designed in the data processing module and is used for transparent transmission of information acquired by the data acquisition module. Therefore, the acquired information is transmitted only by sending a carrier embedded with secret information to a receiver, so that data communication energy consumption is reduced. However, the data communication energy consumption in the sensor network is vital to the sensor network life cycle, and the method has the advantages in the aspect of safety energy-saving communication of data in the multi-media sensor network.

Description

technical field [0001] The invention relates to a safe and energy-saving communication method applied to a wireless multimedia sensor network based on digital image information hiding technology, and belongs to the field of wireless multimedia sensor network security and communication. Background technique [0002] As we all know, the Internet of Things is composed of perception layer, network layer and application layer. The first two layers are the foundation, and the third layer is the application. The network layer is supported by mature communication networks such as the Internet, mobile communication network, and satellite communication network. transmitted to the destination. However, the perception layer is an important foundation of the Internet of Things. How to transmit the data collected by the perception layer (such as the data collected by the wireless sensor network) to the base station (sink node) efficiently, reliably, and safely restricts the Internet of T...

Problems solved by technology

Cryptography mainly uses techniques such as replacement and scrambling to scramble the original characteristics of the secret information, thereby hiding the original content of the secret information, but it is precisely because of the disorder of the scrambled content that it is very easy to cause attacks during transmission. Therefore, the security of secret data can only be improved by increasing the length of the key and the complexity of the encryption algorithm.

At the same time, managing the keys also requires a lot of overhead, which can only be widely used on the Internet with high-performance processors and sufficient energy

In wireless multimedia sensor networks, due to the limited computing power, storage capacity, power supply energy and communication capacity of nodes, cryptography technology cannot be widely and fully applied.
