    Integer wavelet transform‐based secret image sharing using rook polynomial and hamming code with authentication by Sara Charoghchi, Zahra Saeidi, Samaneh Mashhadi

    Published 2024-12-01
    “…In order to make the scheme robust to steganalysis, the shadow image is embedded in coefficients of Integer wavelet transform of the cover image. Using Rook polynomial makes the scheme more secure and moreover makes authentication very easy and with no need to share private key to participants. …”

    Cryptographic hardness assumptions identification based on discrete wavelet transform by Ke Yuan, Yu Du, Yizheng Liu, Rongjin Feng, Bowen Xu, Gaojuan Fan, Chunfu Jia

    Published 2025-06-01
    “…To address this limitation and solve the problem of worse recognition performance of conventional ciphertext analysis methodologies in assumption identification, this paper proposes a cryptographic hardness assumption identification scheme based on the Discrete Wavelet Transform. In this scheme, seven common types of wavelets are considered, including Discrete Meyer, Reverse Biorthogonal, Biorthogonal, Daubechies, Symlets, Coiflets, and Haar. …”
