基于Kyber交换加密水印算法设计

Design of Exchange Encryption Watermarking Algorithm Based on Kyber

摘要: 随着量子计算的迅速发展，传统的同态加密水印算法面临着安全威胁。本文提出了一种基于Kyber密文域同态加密水印算法。通过将Kyber加密算法与Patchwork水印算法相结合，确保信息在传输时不被泄露，同时实现加密与水印嵌入运算先后顺序的交换。实验结果表明，该算法确保了水印嵌入与数据加密的顺序不影响密文数据的生成和水印提取，不仅在密文域可以提取水印，解密后也可以提取水印。

Abstract: The rapid development of quantum computing, traditional homomorphic encryption watermark algorithms face security threats. This paper proposes a watermark algorithm based on Kyber ciphertext domain homomorphic exchange encryption. By combining Kyber encryption with Patchwork watermark algorithm, we ensure that information is not leaked during transmission, and at the same time, the order of encryption and watermark embedding operations is exchanged. Experimental results show that the algorithm ensures that the order of watermark embedding and data encryption does not affect the generation and watermark extraction of ciphertext data. Not only can the watermark be extracted in the ciphertext domain, but the watermark can also be extracted after decryption.
