Abstract

A dynamic image encipherment system, along with an authentication and key exchange protocol (AuthKeX), is proposed for securing images communicated between satellites and base stations. The symmetric encipherment system utilizes dynamic substitution boxes (S-box) and permutation boxes (P-box). The dynamic P-boxes are meticulously crafted using the Fisher–Yates shuffling method, strengthened by the JoanS-MuraliP (JSMP) map. The JSMP map, renowned for its one-dimensional discrete nonlinear characteristics and extensive chaotic regime, enhances the cryptographic strength of this approach.

The AuthKeX protocol facilitates the secure distribution of symmetric keys essential for the encipherment system while also providing robust authentication and non-repudiation services. This protocol is grounded in the principles of Elliptic Curve Cryptography, ensuring a high level of security.

Rigorous security testing on the encipherment system has demonstrated its resilience against various statistical and differential attacks. Notably, the system exhibited a flawless 100 % Non-Linear Pixel Change Rate (NPCR), outperforming existing state-of-the-art methods. Additionally, the proposed AuthKeX protocol is impervious to man-in-the-middle attacks, ensuring the integrity of communication channels. This comprehensive approach marks a significant advancement in image confidentiality and trustworthy communication within satellite environments.

采用动态加密和AuthKeX协议的安全卫星图像传输

提出了一种动态图像加密系统，以及认证和密钥交换协议（AuthKeX），用于保护卫星和基站之间通信的图像。对称加密系统采用动态替换盒（S-box）和排列盒（P-box）。动态p -盒是使用Fisher-Yates洗牌法精心制作的，并由JoanS-MuraliP （JSMP）地图加强。JSMP映射以其一维离散非线性特征和广泛的混沌状态而闻名，增强了该方法的加密强度。AuthKeX协议促进了加密系统所必需的对称密钥的安全分发，同时还提供了健壮的身份验证和不可否认服务。该协议基于椭圆曲线密码学原理，确保了高水平的安全性。对加密系统进行了严格的安全测试，证明了其对各种统计和差分攻击的弹性。值得注意的是，该系统显示出完美的100%非线性像素变化率（NPCR），优于现有的最先进的方法。此外，提议的AuthKeX协议不受中间人攻击的影响，确保了通信渠道的完整性。这种综合方法标志着卫星环境中图像保密性和可信通信方面的重大进步。

期刊介绍： The COSPAR publication Advances in Space Research (ASR) is an open journal covering all areas of space research including: space studies of the Earth''s surface, meteorology, climate, the Earth-Moon system, planets and small bodies of the solar system, upper atmospheres, ionospheres and magnetospheres of the Earth and planets including reference atmospheres, space plasmas in the solar system, astrophysics from space, materials sciences in space, fundamental physics in space, space debris, space weather, Earth observations of space phenomena, etc. NB: Please note that manuscripts related to life sciences as related to space are no more accepted for submission to Advances in Space Research. Such manuscripts should now be submitted to the new COSPAR Journal Life Sciences in Space Research (LSSR). All submissions are reviewed by two scientists in the field. COSPAR is an interdisciplinary scientific organization concerned with the progress of space research on an international scale. Operating under the rules of ICSU, COSPAR ignores political considerations and considers all questions solely from the scientific viewpoint.
