Implementing a hybrid Compression Encryption Technique for Securing WMSN on FPGA

Abstract

Wireless Multimedia Sensor Network (WMSN) is an environment for transferring images, audios, and videos. However, it has many restrictions and limitations that affect the security level as well as the required power consumption. This project is to implement the protection of sensitive data transmission through wireless networks with high performance and low power consumption. The implementation is based on Field-Programmable Gate Array (FPGA) using the

Verilog HDL hardware language for the hardware programming and C/C++ high- level languages for the software programming of the FPGA. The project

implementation is proposed for the solution that was presented by Hraini.[1] In the hardware implementation, RGB images are included in addition to the grayscale images in the software solution. Images are compressed by Set Partitioning in Hierarchic Tree (SPIHT) algorithm[2] and encrypted selectively during the compression process (i.e. jointly). The importance of this project lies in being useful in making a secure environment for transferring images through the most unsecured networks which are wireless networks such as Bluetooth as was applied in this project. The expected results are a hardware implementation that corresponds to the software solution in Hraini’s thesis. Also, the system is expected to present secure transmission for RGB and grayscale images through wireless networks in addition to perform the proposed security solution in a way that guarantees a minimum use of power consumption and high performance. Also, it is expected to satisfy the data confidentiality and privacy the software solution aimed to apply besides having a very compact output bitstream and a constant bitrate in both parties (i.e., sender party and receiver party) as has been achieved in the software solution.
