Meaningful ciphertext encryption algorithm based on bit scrambling, discrete wavelet transform, and improved chaos
Abstract This paper proposes a meaningful ciphertext encryption algorithm of good practicability and strong robustness. The plaintext undergoes pre‐encryption of bit scrambling and secondary encryption of discrete wavelet transform (DWT) to obtain meaningful ciphertext. In the pre‐encryption stage,...
