access icon free Image encryption by chaos mixing

The need for image encryption is constantly on the rise and has led to the emergence of many techniques in literature. In recent years, many chaos-based encryption techniques have developed with more or less success. In this study, we suggest one such approach using two oscillators. Mixed chaotic maps from the Colpitts and Duffing oscillators were used to encrypt images, which helped to increase the key space to 2448 ≃ 7.26 × 10134. The authors also succeeded to reduce the encryption time by saving the mixed chaotic maps and reusing them as need arose. The proposed system was tested on well-known images like Lena, NebulaM83, Mandrill and Clown.
