The evergrowing virtualised information technology infrastructure is powered by cloud-centric technology around the world. Cloud-based multimedia storage has become an essential aspect for users and business behemoths. However, as per a survey of Norton, around 3800 breaches have been publicly disclosed with 4.1 billion numbers of records exposed in 2019, which is a 54% rise when compared to 2018. So the data security is a widely quoted barrier for cloud storage. Ciphering the confidential images before transmission and subsequent storage in cloud database needs critical attention for techno-specific applications. In image encryption, chaos-based keys can do better confusion, but the diffusion process using XOR is vulnerable to chosen plain text attack. The proposed colour image encryption scheme innately uses Deoxyribo Nucleic Acid coding that blends well with chaotic cryptosystem for an efficient statistical shift. The ciphered images are stored in authenticated and authorised cloud storage facilities. The experimentation is carried out with the help of Amazon Web Services storage instances. The proposed image encryption scheme offers a strong resistance towards the brute force, occlusion, statistical and differential attacks and yields near-zero correlation and good entropy.

用于高度安全和基于云的彩色图像存储的高级框架

不断发展的虚拟化信息技术基础架构由全球以云为中心的技术提供支持。基于云的多媒体存储已成为用户和企业巨头的重要方面。但是,根据对Norton的一项调查,2019年公开披露了约3800起违规事件,记录数量达到41亿条,与2018年相比增长了54%。因此,数据安全性被广泛引用为云存储的障碍。对于技术特定的应用程序,在传输和随后存储在云数据库中之前对机密图像进行加密需要特别注意。在图像加密中,基于混沌的密钥可以更好地进行混淆,但是使用XOR的扩散过程很容易受到选定的纯文本攻击。所提出的彩色图像加密方案固有地使用脱氧核糖核酸编码,该编码与混沌密码系统很好地融合在一起,从而实现了有效的统计移位。加密的图像存储在经过身份验证和授权的云存储设施中。该实验是在Amazon Web Services存储实例的帮助下进行的。所提出的图像加密方案对强力,遮挡,统计和差分攻击具有很强的抵抗力,并产生接近零的相关性和良好的熵。
