| Popis: | Actually, images are widely used in various real applications, such as Internet communication, multimedia systems, medical imaging, telemedicine, monitoring, and military communication, so their security is becoming very important. Basically, encryption is one of the best alternative way to ensure information security. In this research work, we propose a hybrid encryption algorithm for the digital grayscale image. The developed approach is based on the combination of Fibonacci sequence with the chaotic logistic map to create the secret key in order to improve encryption quality. Numerical results using a set of image benchmarks have shown the capability of the proposed encryption model to produce a better image security compared to results given by some other recently literature works. |
