Workflow of DNA cryptography (Encryption process: The plaintext was encrypted with the key after the data processing by using the self-assembly structure; then transmits the fluorescence signal in common channel, and the random numbers were encrypted with steganography and transmitted with the secret information.

Abstract

Decryption process: the decipher first decrypts the random numbers to restructure the self-assembly structure; the key is generated according to the key parameters, then the key and ciphertext are decrypted by XOR operation using the self-assembly structure; the plaintext information is restored after data processing).</p
