Summary: | The invention discloses an image encryption/decryption method based on an LNBT hybrid chaos mechanism. The method comprises the following steps: S1, receiving input information comprising an image to be processed and an encryption/decryption identifier; s2, identifying the encryption/decryption identifier, judging that the image to be processed is a plaintext image and executing step S3 when the encryption/decryption identifier is identified to be encrypted, and judging that the image to be processed is a ciphertext image and executing step S4 when the encryption/decryption identifier is identified to be decrypted; s3, initialization is executed, a key stream is generated, an S-Box and a P-Box are constructed, and then the step S5 is executed; s4, initialization is executed, a key stream is generated, and an inverse S-Box and an inverse P-Box are constructed; s5, executing at least one operation of column scrambling, column replacement, column diffusion, row diffusion, row replacement and row scrambling to pe |
