Image encryption and decryption using 3D-AES block cipher algorithm / Engku Maryam Syahdina Engku Safruddin

Cryptography is the way of storing and transmitting data by convert the information into unreadable cipher for security which only intended sender and receiver only could access. The transformation of original data to cipher data is called encryption, while the reverse is called decryption. The basic advanced encryption standard is still not satisfying to achieve the security goals. Whether the key is not so strong or the time needed for processing is slow. In order to ensure the image data is secure/ protected and encryption time is low, it is very timely to conduct a research on image encryption and decryption using 3D-AES block cipher algorithm. The aim of this study were to conduct a research on how to identify the implementation of security analysis of image using 3D-AES block cipher algorithm. Subsequent to this, this project focus on how to measure the security analysis on randomness test of image. The result of this project is the characteristics of 3D-AES is very high in security and this algorithm is resistance to all identified attacks, the system effectiveness and accuracies of the process. Testing algorithm will compute number of bit errors and bit error rate by comparing encryption and decryption. Total average for bit error rate of 30 images is 0.59233. Average above 0.5 prove that the level of security encryption and decryption is very high and secure.
