Popis: | An evolutionary asymmetric cryptosystem is proposed using QWT + SPIHT and AES. This system is based on the Quincunx wavelet transform coupled with progressive encoder SPIHT (QWT + SPIHT) and encrypted by the algorithm “Advanced Encryption Standard” (AES). The numerical results demonstrate that the proposed system is feasible and effective for encryption. The characteristics of the proposed transmission system are as follows. First, the progressive SPIHT encoder performs partial encryption on the compressed image and hash of the image to obtain secure deduplication of the image. Second, the use of the AES encryption algorithm can greatly improve security, such as an attack without phase recovery and information disclosure. The proposed method effectively prevents information leakage. However, adopting a Quincunx wavelet transformation reduces the amount of data, which is more conducive to data transmission and increases the practicability of the system. |
