Images, as one of the important carriers for information exchange, play an important role in work and daily life.
Image encryption technology has received a lot of attention, and varieties of encryption technologies for images have emerged.
Early image encryption technologies have shortcomings such as simple algorithm structure, small key space, and poor resistance to plaintext attacks.
These algorithms have been unable to meet the needs of information security at this stage.
Based on the wavelet algorithm, chaos algorithm, and cyclic encryption algorithm, combined with frequency domain encryption and spatial domain encryption, a digital image encryption algorithm based on adaptive wavelet is proposed in this paper.
In terms of frequency, this paper enhances the adaptive ability of the wavelet algorithm by convex optimization-particle swarm optimization (PSO).
At the same time, the chaotic algorithm is used to scramble the low-frequency coefficients.
In the aspect of airspace, this paper uses the block-encryption adaptive encryption algorithm to rescramble the wavelet-reconstructed image.
And the SHA-1 algorithm is introduced into the plaintext image generation key sequence as a cyclic index value for cyclic encryption.
The key composition of the encryption algorithm proposed in this paper is complex, and the idea of a one-time pad is used, which makes the improved algorithm increase the key space and improve the ability to resist the choice of plaintext attack.
In each cyclic encryption of the airspace, mutual encryption is performed by image subblocks, and the algorithm adaptability is improved.
Through the experimental test of statistical characteristics, key space, and key sensitivity, the encryption performance of the algorithm is verified, and it has strong antiattack and interference ability.
It is a relatively secure encryption algorithm.
