Open publisher page 0 citations

Abstract

A hybrid encryption algorithm based on wavelet transform is proposed. The wavelet transform and improved Zigzag transform are used for image compression and image scrambling. The chaotic sequence matrix is used for xor encryption scrambling.The experimental results show that the algorithm is simple and quick. The key space is large and the key sensitivity is strong.
