OPTIMIZATION ENERGY EFFICIENT OF CRYPTOGRAPHY AS ENCRYPTION AND DECRYPTION IMAGE USING ECC FOR APPLY IN SECURE ONE-WAY COOPERATIVE IMAGE TRANSMISSION
Main Article Content
Abstract
The paper an image compression structure the adaptive JPEG2000 image compression technique using the wavelet image transform is designed. The use of CS for periodic data transmissions is proven as an effective solution for WSNs as observed in CS-based sensor communications reduce data transmissions and improve energy efficiency significantly. But another challenge while using the compression is data loss due to different security threats during the transmission. The image is compressed data is more vulnerable to the different wireless channel threats. This paper addresses the security issues for compressed data by using the modified ECC-based cryptography method. The key problem of the conventional ECC method is the complicated and time-consuming task of scalar multiplication which may consume the extra energy of sensor nodes, so energy consumption is optimized by elaborating the steps of ECC-based encryption and decryption in the proposed ECC-based model. The main aim of improving the image quality with minimum processing time and error rates. However, for WMSNs, force aptitude is also an essential research challenge as the high-dimensional digital images consume more processing capabilities of sensor nodes. In WMSN, the image is transmitted through a large number of relays; thus the larger the transmissions the more the energy consumption. The compressed data at the receiver end is decompressed with poor quality, hence securing the compressed data by using the lightweight security method is important while planning the helpful picture transmission model. In this chapter, we propose our next research contribution to alleviate the challenges of security and energy efficiency for cooperative digital image transmission.
