随着卫星和网络通信技术的大规模发展，人们对卫星图像在互联网和共享网络环境中的安全存储和传输提出了很高的要求。这给保护敏感和关键的卫星图像免受未经授权的访问和非法使用带来了新的挑战。在本文中，我们解决了上述问题，并开发了消除相关问题的技术。为此，我们提出了一种新的基于混沌的卫星图像对称密钥加密技术。该方案利用Logistic、Henon、Tent、Cubic、Sine和Chebyshev等多个混沌映射来增强卫星图像的密钥空间、稳健性和安全性。我们进行关键灵敏度、统计和性能分析实验，以确定我们的卫星图像算法的安全性、可靠性和速度。与AES、3-DES和DES算法相比，该算法具有较高的安全性、足够大的密钥空间、像素分布均匀和可接受的加密速度等特点。(C)2010爱思唯尔有限公司。保留所有权利。
With the large-scale development in satellite and network communication technologies, there is a great demand for preserving the secure storage and transmission of satellite imagery over internet and shared network environment. This brings new challenges to protect sensitive and critical satellite images from unauthorized access and illegal usage. In this paper, we address the aforementioned issues and develop techniques to eliminate the associated problems. To achieve this, we propose a new chaos-based symmetric-key encryption technique for satellite imagery. This scheme utilizes multiple chaotic maps e.g. Logistic, Henon, Tent, Cubic, Sine and Chebyshev for enhancing the key space, robustness and security of satellite imagery. We perform key sensitivity, statistical and performance analysis experiments to determine the security, reliability, and speed of our algorithm for satellite imagery. The proposed algorithm presents several interesting features, such as a high level of security, large enough key space, pixel distributing uniformity and an acceptable encryption speed as compared to AES, 3-DES, and DES.
