Abstract

The invention belongs to the technical field of optical information, and particularly relates to a DNA image encryption system based on optical chaos. The system comprises a first laser device, a second laser device, a third laser device, a fourth laser device, a fifth laser device, a sixth laser device, a seventh laser device, a first secret key generator, a second secret key generator, a third secret key generator, a fourth secret key generator, a fifth secret key generator, a sixth secret key generator, a first reflector and a first beam splitter. According to the invention, the secret keysare generated at the encryption end and the decryption end by using the chaos principle, so that the secret keys of the three components of the color image are respectively generated by the three slave lasers controlled by the same laser, and the secret keys and the three components of the color image are operated through DNA encryption operation, so as to encrypt the color image. The system hasthe characteristics of cost saving, high encryption speed, low power consumption and high confidentiality.

Description

technical field [0001] The invention belongs to the field of optical information technology, in particular to a DNA image encryption system based on optical chaos. Background technique [0002] Chaos is a science developed in recent decades. Since the chaotic system has the characteristics of pseudo-random signals similar to noise and is robust to interference, chaos is widely used in secure communication, image encryption and signal detection. All have broad prospects. The key to realize chaotic image encryption is the generation of chaotic key, the complexity of chaotic key will directly affect the encryption performance of digital image. Using optical devices to realize chaotic image encryption has the characteristics of low cost, large key space, stable performance, and strong confidentiality. [0003] At present, the encryption idea of ​​the traditional encryption algorithm is to regard the plaintext information as a one-dimensional binary stream for encryption operat...
