Popis
Shrnutí:In the fifth generation of technology, data security is a critical concern due to the large set of applications which are based on data communication and computing, and hence data encryption plays a pivotal role in the protection of vital information from unauthorized access. For protecting information, various algorithms based on mathematical cryptography, hashing have been proposed along with chaos-based techniques. This paper offers a colour image data encryption technique with double security based on key generation using a Linear Feedback Shift Cipher (LFSR) and a 2-D Henon chaotic dynamical system. The method begins by generating a pair of keys using a chaotic Henon map and LFSR. These keys drive the encryption process for colour images, enhancing confusion, and the diffusion process. The generation of random number sequences derived from a chaotic Henon map which depends on two initial conditions as well as seed value in LFSR. A generated random sequence is then derived to control the encryption process. The proposed method ensures lossless encryption, achieves robustness against various noise inclusion, tampering attacks and cutting plane attacks, and exhibits key randomness as per the NIST statistical randomness testing suite. Along with various statistical tests, dynamical properties of key generation using the Henon map are tested and show relevant results. The strength of the proposed encryption technique is also verified by testing it against differential attacks. A fair comparison of the proposed one with various enduring algorithms in testing the randomness of the generated key using the chaotic Henon map and LFSR proves the applicability of the encryption scheme in real-time data.
