DWT-AES BASED INFORMATION SECURITY SYSTEM FOR UNMANNED VEHICLES

摘要

Security of data is crucial in present day telecommunication framework, AES algorithm is one of the prominent methods for information Encipherment. For secure image communication needed for unmanned robotics, Discrete Wavelet Transform (DWT) is embraced for image decomposition, quantization and determination of appropriate sub bands is needed to precede encryption and to decrease execution time. In this paper, a modified algorithm for secure image encoding is proposed, demonstrated and is examined for its execution. Different images are considered as experiments for encoding, with parallel operation of AES algorithm the aggregate time in encoding the image is decreased to 2 seconds (evaluated focused around programming reference model). PSNR for different images acquired exhibit the exhibitions of the proposed model for image encoding. Image size of 1024x1024 is considered for encryption and unscrambling. The results got exhibit the exhibitions of AES algorithm.
