Design Sequential Hybrid Lightweight Algorithms For Encryption Data Using RC6 Algorithm

  In this study, a novel hybrid encryption scheme is proposed for secure encryption of various types of data such as images, text, documents, and videos. The scheme employs 6D chaos to generate unpredictable and highly secure keys for the RC6 encryption algorithm. The proposed method also constructs eight new S-boxes and eight new P-layers to enhance the security of the encryption process. The S-boxes and P-layers are generated using chaotic initial state parameters and stored in arrays for use in the encryption process. The encryption process uses the RC6 algorithm, S-boxes, and P-layers, with eight rounds of encryption. The resulting cipher text is highly secure and suitable for protecting sensitive data. The proposed scheme is evaluated for security and efficiency using various metrics, and the results show that the proposed scheme outperforms existing methods in terms of security and efficiency. The proposed scheme is a promising approach for secure encryption of various types of data in real-world applications. The test results indicate to the highest value of peak signal-to-noise ratio (PSNR), unified average changing intensity (UACI), number of pixel change rate (NPCR) are 7.748 dB, 33.4842 and 99.6082, respectively. While the encryption and decryption speed up 0.1735 and 0.1864 second respectively.
