A novel encryption model for text messages using delayed chaotic neural network and DNA cryptography

Increasing Randomization of Ciphertext in DNA Cryptography

“…The algorithm aims to transmit the One-time-pad (OTP) securely, but execution time has been increased as compared to other similar techniques. Interestingly a cryptographic system is designed, where the authors in [8] apply a delayed Hopfield neural network to generate the cryptographic key before DNA encryptiondecryption process. Specifically, the chaotic neural network generates a binary sequence, passed on to the permutation function yielding the first level key for encryption.…”

“…All these research works endorse the fact that DNA encryption using DNA encoding can significantly improve the security of the cryptographic solution. A similar approach in [8] is extended with the existing DNA encoding table at a carefully selected location. The subsequent section explains the encryption process for the base technique followed by the improved technique with an additional layer of the dynamic sequence table.…”

“…This research work focuses on the change in ciphertext from a plaintext perspective. A detailed study of DNA cryptographic encryption algorithm as in [8] indicates that the avalanche effect is considerably less, leading to security vulnerabilities. Specifically, the conversion of the binary data into DNA bases (00 to A, 01 to G, 10 to C, 11 to T) exhibits poor avalanche effect or randomization of the ciphertext.…”

An Information Security Using DNA Cryptography along with AES Algorithm

“…In [3] Author SudiptaSingha Roy and etc had proposed and explained a novel encryption methods. It is proposed using delayed chaotic neural network with a posterior DNA cryptog-raphy.…”

“…The authors suggested that DNA based AES algorithm provide triple layer security. They also discuss about methods and steps involved in the proposed DNA encryption and decryption [2].Authors explain a cryptographic model, which is proposed for text messages by using chaotic neural network along with transmogrify delay for encryption to first step DNA cryptography [3].…”
