Ensuring the confidentiality of any data exchanged always presents a great concern for all communication instances. Technically, encryption is the ideal solution for this task. However, this process must deal with the progress of the cryptanalysis that aims to disclose the information exchanged. The risk increases due to the need for a dual transmission that includes the encrypted medium and the decryption key. In a context of chaotic encryption of images, we propose to insert the decryption key into the encrypted image using image watermarking. Thus, only the watermarked encrypted image will be transmitted. Upon reception, the recipient extracts the key and decrypts the image. The cryptosystem proposed is based on an encryption using a dynamic Look-Up Table issued from a chaotic generator. The obtained results prove the efficiency of our method to ensure a secure exchange of images and keys.

将密钥安全传输到加密图像中的加水印

确保所有交换数据的机密性总是引起所有通信实例的高度关注。从技术上讲,加密是完成此任务的理想解决方案。但是,此过程必须处理旨在揭示交换的信息的密码分析的进度。由于需要包括加密介质和解密密钥的双重传输,因此风险增加。在对图像进行混沌加密的情况下,我们建议使用图像水印将解密密钥插入加密的图像中。因此,将仅发送带有水印的加密图像。在接收时,接收者提取密钥并解密图像。提出的密码系统基于使用从混沌发生器发出的动态查找表的加密。
