Cloud computing plays a vital task in our daily lives, in which an enormous amount of data is stored daily on cloud storage. The highest priority for cloud data storage is guaranteeing the security of confidential data. The security of confidential data can be realised through utilising one of the cryptographic mechanisms including encryption and data hiding. With the rapid development for the realization of quantum computers, modern cryptosystems may be cracked including cloud systems. Accordingly, it is a crucial task for achieving confidentiality of data stored on cloud storage before the availability of quantum computers. Therefore, this study aims to utilise one of the quantum computational models, as a quantum-inspired system, to layout a new data confidentiality technique that can be applied in digital devices to have the capability for resisting the potential attacks from quantum and digital computers. In this paper, a new image security algorithm for real-time cloud applications using Gray code, quantum walks (QW), and Henon map is proposed. In the proposed image cryptosystem, the generated key streams from QW and Henon map is related to the plain image with high sensitivity of slight bit changes on the plain image. The outcomes based on deep analysis proves that the presented algorithm is efficient with high security for real-time application.

一种使用格雷码、量子游走和 Henon 映射的云应用新型图像密码系统

云计算在我们的日常生活中发挥着至关重要的作用,每天都有大量的数据存储在云存储中。云数据存储的重中之重是保证机密数据的安全。机密数据的安全性可以通过利用包括加密和数据隐藏在内的加密机制之一来实现。随着量子计算机实现的快速发展,现代密码系统可能会被破解,包括云系统。因此,在量子计算机可用之前实现存储在云存储上的数据的机密性是一项至关重要的任务。因此,本研究旨在利用其中一种量子计算模型,作为量子启发系统,设计一种新的数据保密技术,可应用于数字设备,以抵御来自量子和数字计算机的潜在攻击。在本文中,提出了一种使用格雷码、量子游走 (QW) 和 Henon 映射的实时云应用程序的新图像安全算法。在所提出的图像密码系统中,从 QW 和 Henon 映射生成的密钥流与普通图像相关,对普通图像上的微小比特变化具有高灵敏度。基于深度分析的结果证明,所提出的算法是有效的,并且对于实时应用具有高安全性。在所提出的图像密码系统中,从 QW 和 Henon 映射生成的密钥流与普通图像相关,对普通图像上的微小比特变化具有高灵敏度。基于深度分析的结果证明,所提出的算法是有效的,并且对于实时应用具有高安全性。在所提出的图像密码系统中,从 QW 和 Henon 映射生成的密钥流与普通图像相关,对普通图像上的微小比特变化具有高灵敏度。基于深度分析的结果证明,所提出的算法是有效的,并且对于实时应用具有高安全性。
