A novel encryption scheme for secure communication based on RNA - CSI Transactions on ICT

Design of RNA-based encryption schemes such as speed, security, and scalability utilize RNA molecules to encrypt and decrypt images in recent years. RNA-based encryption schemes have been proposed as a potential solution for secure communication. RNA molecules are used to encrypt messages, and the encrypted message can only be decoded using a complementary RNA sequence. In this paper, we propose a novel RNA-based encryption scheme that uses pixel depth to encode the RNA sequence. Our method employs the property of RNA sequences that their complementary sequences fold into specific shapes and assign each nucleotide in the RNA sequence a pixel value based on its location in the folded structure, and then uses the pixel depth of these values to encode the message. We also demonstrate the effectiveness of the proposed method by encrypting and decrypting messages of varying length and complexity. Our approach is resistant to attacks based on frequency analysis, and it has potential applications in secure communication systems.
